Orun is a “jack of all trades,” capable of learning almost any skill but never truly mastering one. One day, his childhood friend and party leader, Oliver, kicks him out of their S-rank hero party. While Oliver tries to be gentle by explaining that keeping him around would just slow them down, their teammates Aneli and Derrick rudely call Orun dead weight.
Heartbroken, Orun reflects on how he and Oliver founded the party eight years ago and achieved massive success together in the Great Southern Dungeon. Oliver explains that he recently saw another S-rank party’s support mage in action, making him realize how lacking Orun‘s support magic actually is. Orun knows this is true; he originally trained as a swordsman but switched to support magic to balance the team.
However, Derrick cruelly points out that Orun only switched because Oliver is a far superior swordsman. Though Orun can use both magic and a sword, his skills are painfully average compared to the rest of the group. Since Oliver has already found a replacement enchanter and the rest of the team clearly resents him, Orun realizes he has no reason left to stay.
As Orun walks out, Aneli cruelly remarks that she is glad he won’t be bossing them around anymore, claiming his skills are only suited for an A-rank adventurer. Stung by her words, Orun heads to the southern dungeon alone to prove his worth. By combining his sword skills with continuous self-buffing magic, he easily handles groups of goblins. He is determined to perfect his mid-combat spellcasting so he is never called worthless again.
Later, while registering at the seventh-floor teleportation crystal, Orun overhears a panicked party returning. Their leader justifies abandoning a female teammate during an orc ambush to save themselves. Furious at the thought of a party abandoning one of their own, Orun confronts them. When a party member tries to punch him, Orun effortlessly flips him to the ground, demands the girl’s location, and rushes off to help.
Meanwhile, the abandoned girl is trapped, her protective barrier shattering under the orcs’ relentless attacks. Just as the monsters break through and her fate seems sealed, Orun arrives in the nick of time. He casts a powerful wind spell to blast the orcs back, stepping in front of the girl to protect her.
Shocked by her unexpected rescue, the girl watches as Orun charges forward to intercept the attacking orcs. Sophia assumes he is just a swordsman, but is amazed when Orun casts support magic mid-battle. He slices an orc in half and enchants his sword with Sharpness Five to effortlessly handle the rest. Realizing the sheer size of the horde, he briefly understands why the previous party fled, but he easily massacres the monsters to Sophia‘s astonishment.
Afterward, Orun checks on her, but the overwhelmed girl collapses in tears. He comforts her and escorts her safely out of the dungeon. As he tries to leave, she introduces herself as Sophia. Orun recognizes her prestigious family name and the crest on her cloak. After introducing himself, he reluctantly accepts her insistent offer to treat him to dinner as a thank you.
She takes him to a modest but favorite restaurant of hers. Orun notices the building bears the same crest as her cloak, confirming she belongs to the powerful Night Sky Silver Rabbits guild. This makes him worry about getting tangled up in complicated clan matters. Suddenly, Sophia spots her sister, Selma, eating nearby. Selma initially teases Sophia for being on a date with a man, but is shocked when she realizes he is actually Orun. While Sophia is surprised they know each other, Orun knows he could never forget Selma.
Selma is the continent’s most powerful enchanter, whose skills set the standard for support mages—and inadvertently caused Orun to be kicked out of his party. Orun had no idea Sophia was related to her and is confused by Selma‘s intense glare. She aggressively confronts him about dating her 14-year-old sister so late at night. Orun quickly denies any romantic interest, but his blunt phrasing only angers Selma more, as she assumes he finds Sophia unattractive.
Sophia quickly intervenes, revealing that Orun just saved her life. Mortified, Selma apologizes profusely. As they sit down together, they recall working closely as enchanters during a joint raid last month. When Selma praises his skills and assumes he is still in the hero’s party, Orun reveals his recent expulsion. Shocked that anyone would abandon someone so useful, Selma immediately offers him a well-paying, three-day job guiding new recruits on a 50th-floor teaching expedition.
Even though A-rank adventurers will lead the group, Selma insists his proven expertise would make her feel much better. While honored by her respect, Orun still feels inadequate compared to her abilities. Determined not to limit himself to support magic again after just being fired over it, he politely declines, leaving Selma completely surprised by his refusal.
Selma backs off, but Sophia begs Orun to reconsider, admitting she would feel much safer with him on the expedition. Reluctant to be just an enchanter again, Orun is swayed by her pleading and promises to think it over. Selma is pleased, but Orun clarifies he will only join if he is allowed to fight with his sword. Surprised and doubtful of his sword skills, Selma assumes he will simply revert to magic if things get tough. She tells him to meet at the Silver Rabbit HQ the next morning if he accepts, and they part ways for the night.
Before heading home, Orun visits a familiar weapon shop. The owner thanks him over tea for boosting his business through word-of-mouth recommendations. Orun apologizes, explaining that since he was kicked out of the hero’s party, his recommendations will no longer carry any weight. However, the shopkeeper warmly reassures him that he has nothing to apologize for; he is still the same great person. Encouraging him to live for himself, the old man reminds Orun that he is still a true hero at heart.
The next morning, Orun heads to the Silver Rabbit HQ. There, he meets the guild president, Vince, who has already heard great things about him and is thrilled to finally meet him.
Orun asks for more details before committing. Vince has Selma explain the plan: they will guide ten rookie parties down to the 51st floor, reaching the 21st on the first day. The five escorts, including Orun and Selma, will only intervene during emergencies.
Earlier, Selma and Vince had privately discussed how foolish the hero party was to expel Orun. While his spell potency is lower, his casting speed is four times faster than Selma‘s. By simultaneously juggling multiple original spells and constantly analyzing the battlefield, he secretly carried his old team. Selma figures his flawless efficiency made his massive contributions completely invisible to them.
Back in the meeting, Orun questions why there are only five escorts for such a fast-paced, risky schedule. Selma claims it is to challenge the rookies, but Orun instantly suspects a hidden agenda. Realizing they won’t tell an outsider their true objective, he drops the subject. Relieved, Vince offers a massive payout: two gold pieces upfront and ten upon completion. Orun is shocked by the life-changing sum for just a few days of work, but Selma insists he is worth every penny.
The next day, Orun arrives early at the dungeon entrance and watches the new adventurers prepare. Selma and Sophia arrive soon after. Sophia is thrilled to see him, prompting a protective Selma to warn Orun against trying anything with her underage sister.
When asked why he is standing so far away, Orun explains he didn’t want to make the recruits nervous. Agreeing they need to meet him, Sophia introduces him to the other escorts: Anthem, Bernard, and Cathy. Noting that Bernard and Anthem are defenders and Cathy is a healer, Orun realizes the setup is strange. Since Selma originally thought he was only an enchanter, she planned this risky dive without a dedicated frontline attacker out of desperation for the guild to finally make progress.
Dodging his suspicions, Selma introduces Orun to the anxious rookies. She hypes him up as the operation’s cornerstone, revealing he previously reached the 94th floor with the hero party. The recruits are completely awestruck, leaving Orun flustered by the attention.
After a final equipment check, Selma assigns Orun to escort Group 10, the most promising rookies. Orun discovers Sophia is in this group, but wonders why they only have three members instead of four. A confident rookie, Logan, proudly declares it is because no one else could keep up with them.
Logan introduces himself as the team’s enchanter, arrogantly claiming he will one day surpass Selma. Orun appreciates the ambition but finds his attitude problematic. Next, Caroline introduces herself as the defender, confusing Orun since she lacks armor or a shield. She explains she relies entirely on dodging enemy attacks. While dodge-type defenders do exist, Orun warns her that this strategy requires advanced evasion skills and is incredibly difficult for beginners. Logan chimes in that teachers warned her repeatedly, but she ignored them, instantly sparking a bickering match between the two. Orun finally understands why Selma called this group “special,” feeling relieved that Sophia is at least completely normal.
Once inside the dungeon, the group surprisingly drops the ruckus and behaves very well. Caroline soon asks why Orun is helping them, considering his hero party rivals the Silver Rabbit clan. When Orun clarifies he is no longer in the party, she is shocked and presses for details. Too embarrassed to admit he was kicked out, he bluntly tells her to mind her own business. Undeterred, Caroline playfully teases Sophia for constantly bragging about meeting him the other day. Though embarrassed, Sophia happily admits she thinks Orun is amazing and is thrilled he came along.
As they walk through the cave, a wolf pack appears behind them. Normally, they’d stop to fight, but Orun isn’t worried because he secretly laid traps to instantly deal with sneak attacks. However, by silently guarding their rear without telling anyone, it becomes obvious why his previous party constantly underappreciated his unseen contributions.
Observing the rookies fight, Orun is genuinely impressed. Logan proves he has the enchanter skills to back up his massive ego, though he currently struggles to give instructions as a leader. Caroline has the speed to be a dodge-type defender but is dangerously reckless, instantly charging at monsters the second she sees them. While not as flashy, Sophia is a solid caster with no obvious flaws, showing a promising future.
Day one ends smoothly as they reach the 21st floor. Orun reports to Selma that Group 10 has great potential but completely lacks teamwork, which she already knew.
The next morning, Orun wakes up to disastrous news: his former party has publicly announced his expulsion. Knowing the students admired him as a hero, he dreads how this will ruin their opinion of him before the expedition is even finished. As he walks to the dungeon for day two, bracing himself for the fallout, someone named Luna suddenly calls out to him in the street.
Luna, another hero party member who was away during Orun‘s expulsion, intercepts him on the street. She was always kind to him and begs him to return, insisting the team still needs his strength. Though Orun wonders if her presence could have changed his fate, he firmly refuses. The public news makes returning impossible, but more importantly, the painful realization that Oliver broke their childhood promise to conquer the Great Labyrinth together proves that their friendship is permanently shattered.
Arriving at the dungeon, Orun finds the students anxiously whispering about the newspaper article that exposed his banishment for being “too weak.” Selma arrives and quickly apologizes for unknowingly hyping him up as an active hero yesterday. However, Orun calmly reassures everyone that his past record and flawless performance yesterday prove his actual skills, regardless of the article.
While Caroline and Sophia still fully trust his abilities, a skeptical Logan demands to know if the rumors are true. Orun honestly admits he was kicked out for being relatively weak compared to his old team, but promises he is still more than capable of guiding them safely to the 51st floor. Completely unconvinced, Logan firmly decides that Orun must just be a useless bum.
Heading into the dungeon, the group easily clears the lower levels to reach the 31st floor, where Orun officially takes the lead. Sensing monsters ahead, he halts the group and prepares them for battle.
When Caroline recklessly charges the goblins, Logan quickly casts a buff on her, deliberately acting before Orun can give the order because he refuses to take instructions from a disgraced hero. Unbothered by the disrespect, Orun focuses on Sophia, who is frozen in terror while facing an orc due to her recent dungeon trauma. Logan angrily assumes Orun is a terrible teacher for not intervening, but he is shocked to realize Orun secretly cast a stealthy agility debuff on the orc to safely buy her time.
Orun gently reminds Sophia that she is no longer alone and has a team to support her. Empowered by his words, she obliterates the monster with an advanced fire javelin, surprising everyone. While Caroline praises her amazing move, a stunned Logan completely reevaluates his harsh opinion, struggling to understand how the hero party could ever expel someone with Orun‘s exceptional combat and casting skills.
Upon reaching the 35th floor, the group faces a giant tarantula. Panicked, Logan considers retreating, but Orun swiftly orders him to cast defensive and agility boosts. Caroline recklessly charges in, and Orun holds Logan back, reminding him to stay safely out of the vanguard. Taking command, Orun instructs Caroline to vault over the spider to strike its back, drawing its aggro while carefully dodging its venom.
Following Orun‘s flawless coordination, Logan maintains the buffs while Sophia severs four of the spider’s legs with well-timed air slashes. Anticipating the monster’s desperate counterattack, Orun orders Logan to buff Caroline‘s strength just before the spider ensnares her in its web. When her boosted strength still isn’t quite enough, Orun secretly enchants her dagger with sharpness, giving her the cutting power needed to break free. Sophia then finishes the beast off with a rock bullet.
After praising their teamwork, Orun and the group return to the surface. Selma advises everyone to rest up for tomorrow’s final push to the 51st floor. As Orun leaves for the day, two other supervisors warmly invite him to grab dinner with them.
Orun happily agrees to join the two friendly supervisors for dinner at the tavern. Meanwhile, heading home in a carriage, Logan deeply reevaluates his harsh opinion of Orun. He asks Sophia about her rescue, and she recalls Orun using a wind spell and a weapon enchantment before slicing through the orcs. Amazed, Logan recognizes that weapon enchantments are incredibly difficult to pull off. He is baffled as to why someone with such elite magic skills would fight with a sword, though Sophia mentions he recently switched to being an attacker.
Logan admits he was completely wrong to doubt him. Orun proved to be a flawless supporter, perfectly analyzing the battlefield, predicting the tarantula’s attack, and effortlessly casting complex debuffs that even Selma struggles with. He is the greatest enchanter Logan has ever seen. When Caroline asks if Orun is actually a strong swordsman, Sophia confirms he easily defeated the orc horde. Hearing this, Logan concludes that Orun must be an absolute genius to master both magic and swordsmanship.
Realizing he can’t currently outdo him, Logan refuses to give up, vowing to learn everything he can from Orun to eventually match his strength.
Meanwhile, Orun enjoys dinner at the tavern with the other supervisors. When asked what he did for fun in his old guild, he admits he never had free time because he handled all their errands and busywork. Disgusted that the news article called him useless when he was clearly the party’s backbone, his new friends urge him to ignore his ungrateful former teammates. Touched by their genuine support, Orun sincerely thanks them.
They then ask why such a highly praised enchanter would switch to being a frontline attacker. Orun explains that his true dream, inspired by his grandfather, was always to be the world’s best swordsman, which was his original role in the hero party. When asked why he ever switched to magic, he reveals it wasn’t by choice. As his old party faced tougher monsters on lower floors, they desperately needed an enchanter to survive. Because Orun was capable of learning almost any skill, the burden of switching roles fell entirely on him.
His new friends point out that Orun‘s sacrifice at least helped his old team reach the 94th floor. Orun disagrees, explaining that rushing their progress left them dangerously unprepared. He insists it would be incredibly foolish for the hero party to venture any deeper in their current state. Sensing his tension, the others change the subject and ask about his goals. Orun reveals his dream to become a self-sufficient “jack of all trades” swordsman who can solo the deepest dungeon floors, a unique ambition his friends firmly believe he can achieve.
Ironically, the hero party is currently marching into the dungeon to do exactly what Orun warned against.
Meanwhile, Orun arrives at the dungeon entrance for the expedition’s final day. Caroline playfully sets up Sophia so she can finally ask Orun to officially join their guild. However, before Sophia can get the words out, Selma calls Orun away. As he walks over, Orun overhears students gossiping that the hero party is attempting a massive deep dive starting from the 92nd floor. He freezes in absolute disbelief, shocked they would risk such a deadly run with a brand-new replacement member and zero time to practice.
Orun initially stresses about their impending disaster but quickly realizes it is no longer his problem. Meanwhile, the hero party reaches the 92nd floor with their new recruit, Philly. Incredibly, they never tested their teamwork beforehand, relying entirely on her impressive resume. Introduced just two days prior, Philly had previously conquered the 100th floor of the western dungeon, leading the group to blindly assume she could easily do the same for them in the south.
Convinced her spells will surpass Orun‘s, Aneli and Derrick start trash-talking him, particularly complaining that he never let them waste the party’s funds on extravagant celebrations. This instantly raises red flags for Philly, who realizes they would be completely broke without Orun‘s strict financial management. Oliver interrupts, urging them to focus on welcoming Philly.
Just then, Luna barges in. Having just learned about Orun joining the Silver Rabbits’ expedition, she is furious to discover she was never consulted about his replacement. While Derrick and Aneli are shocked Orun joined such a prestigious guild so quickly, they dismiss it since he is out of their group.
Luna initially assumed Orun left because he was tired of carrying them, but Derrick proudly brags that they kicked him out. Speechless at their stupidity, Luna reminds them that Orun was the absolute core of their team and the only reason they got this far to begin with, but the arrogant trio completely refuses to listen.
Derrick insists that despite Luna‘s high opinion of Orun, he will always be a substandard loser. Since he is already gone, Luna reluctantly grits her teeth and accepts that she cannot convince Orun to return.
Misinterpreting her silence as agreement, Oliver makes another foolish decision: testing Philly‘s synergy on the dangerous 92nd floor. If successful, he plans to push to the 94th floor to break their record. Wanting to stay alive, Luna immediately objects. She suggests safely testing Philly on the 30th floor, but the oblivious party looks at her as if she were speaking a foreign language.
They completely fail to grasp the danger of training a new member on a floor they barely survived previously. Derrick and Aneli delusionally blame Orun for their past struggles, arrogant in their belief that Philly will make the dive a thousand times easier. Fearing the black dragon on that floor, Luna continues to protest, but Oliver forces her to participate. Unwilling to abandon the team just yet, she reluctantly joins the expedition.
Things go exactly as poorly as she expected. Facing a giant mammoth they would normally defeat with ease, Oliver strikes the beast, but his sword does absolutely zero damage.
Derrick struggles to block the mammoth, and Aneli‘s fire magic is practically useless. The team is confused as to why their attacks are suddenly weaker. Overwhelmed just trying to maintain her basic buffs, Philly cannot analyze the battlefield or give instructions, leaving the team to make their own terrible decisions. Oliver finally realizes they are much weaker than he thought, but he still doesn’t grasp why.
Before Luna can explain their massive mistake, the dreaded black dragon lands, instantly crushing the mammoth and knocking everyone to the ground. Luna screams for them to flee. However, the dangerously delusional trio of Derrick, Aneli, and Oliver foolishly believe they can still win since they beat it once before—completely failing to realize that Orun was the only reason they survived last time.
Derrick confidently tries to block a fireball but is instantly scorched to a crisp. As Luna rushes to heal him, a terrified Philly deeply regrets joining the party. Meanwhile, Aneli hits the dragon with a fire javelin, only to watch in dumbfounded shock as the monster takes absolutely zero damage.
Provoked by the weak flame attack, the dragon targets Aneli and blasts her away. Watching everything fall apart, Oliver begins to panic until Luna snaps him back to reality. With Derrick and Aneli both unconscious, Luna tells Oliver to buy her enough time to heal them. Oliver orders a terrified Philly to cast every buff she can on him and unleashes his ultimate attack. However, his absolute strongest strike is completely negated by the dragon’s fireball, sending him flying and plunging him into total despair.
Disappointed by her leader’s weak will, Luna declares their only option is to use a “fickle gate”—an emergency magic item that instantly teleports the user to a random floor’s boss room. Though Philly fears the unpredictable danger, staying means certain death. Oliver activates the gate, and they gather their injured teammates to jump. At the very last second, the charging dragon cuts them off with a wall of fire and accidentally plunges through the portal itself. While Derrick breathes a sigh of relief that the monster is gone, a horrified Luna screams that this is the absolute worst-case scenario.
Oliver realizes the dragon was teleported to a random boss room, potentially endangering innocent rookie adventurers. Luna urges them to return to the guild immediately to activate the emergency guild card feature, which will force-teleport everyone safely out of the dungeon. Though worried about severe guild penalties, Oliver prioritizes saving lives. However, Luna makes him wait while she finishes healing the incapacitated Aneli and Derrick.
While healing them, Luna drops a bombshell: after triggering the evacuation, they must fight the dragon themselves, and Oliver must swap Philly for Orun. She hates forcing Orun to clean up their mess, but they have no other choice. She finally explains that their sudden weakness is entirely due to Orun‘s absence. Oliver argues this is impossible since his ultimate attack failed, but Luna bluntly blames his own carelessness. Because Oliver has exceptionally high magic resistance, Philly‘s buffs wear off on him in just one minute.
While Orun flawlessly tracked these precise spell timings mid-battle, Philly simply cannot. When Oliver protests that Philly is naturally more talented, Luna agrees—but points out that Orun‘s lack of innate talent is exactly what drove him to invent brilliant original spells to completely overcome his weaknesses.
The rest of the team is completely shocked, as a mage inventing an original spell is incredibly rare. While Orun‘s base enchantments are weaker, his custom spell boosts their potency by fifty times—a feat that stuns Philly, since even Selma can only achieve a ten-fold boost. Luna explains that Oliver‘s ultimate attack failed because he grew lazy; Orun‘s buffs made the skill so efficient that Oliver stopped gathering the necessary energy. Similarly, Aneli grew accustomed to effortlessly using weaker mid-tier spells because Orun‘s magic made them devastating. Since his spells also enhanced their equipment, the party had unknowingly become entirely reliant on his support. Despite finally realizing Orun‘s vital role, Oliver‘s massive ego takes over, and he delusionally convinces himself he previously defeated the dragon without Orun‘s help.
Meanwhile, Orun and his expedition begin their final day, planning to push from the 36th to the 50th floor before safely teleporting out. Although the supervisors will now actively help fight the tougher monsters, Orun cannot shake a terrible, inexplicable feeling of dread about the dungeon. However, the excited recruits quickly distract him, and he brushes his worries aside against his better judgment. When an eager Caroline asks for combat tips so she can kill more monsters, Orun gently reminds her that she still has limits as a beginner.
Orun reminds Caroline that a defender’s true job is to protect the team, not just blindly charge ahead. She complains that holding back isn’t fun, but Logan urges her to listen, noting that the late Albert used to give the exact same advice. The mention of the Silver Rabbit Guild’s famous ace adventurer catches Orun‘s attention. Albert tragically died last year on the 92nd floor fighting the black dragon to protect a teammate—which should have been the defender’s job. Seeing the deep trauma in Caroline‘s eyes, Orun realizes her reckless rushing is a desperate attempt to prevent a similar tragedy. Not wanting to play therapist, he shifts focus as Sophia and Logan eagerly ask for their own combat tips.
Later, while taking a break deeper inside the dungeon, Selma happily notes how much the recruits respect Orun despite the recent negative news article. The conversation shifts back to Albert‘s devastating death. Having barely defeated that same black dragon with his old party, Orun knows Albert didn’t die from weakness; it was just a tragic situation. Selma uses the emotional moment to try recruiting Orun to fill the massive hole Albert left in their guild. Orun declines, stating that a party doesn’t need two enchanters, but Selma insists his new goal of becoming a swordsman still makes him a perfect fit.
Once the mission resumes, the groups are briefed and sent out. Placed at the very back of the formation in Group 10, Sophia feels nervous about being so isolated from the main force. However, Orun reassures them that navigating alone is a crucial learning experience, preparing them for the reality of getting separated in a dungeon’s complex layout.
Logan agrees, but Caroline dreads the idea of getting lost. Orun explains that studying dungeon maps beforehand is crucial to avoiding deadly surprises. Eager to learn, Caroline asks him about the deepest levels. Orun happily explains that the lower floors, starting at 76, are snow and ice-themed, while the true depths begin at 91. However, the excited recruits constantly interrupt him with questions before he can elaborate.
Meanwhile, Luna rushes into the adventurer’s guild with the rest of the hero party, desperately demanding to see the guild master. When the receptionist, Eleanor, informs her he is busy, a frantic Luna insists there is no time to wait and that they must force-teleport everyone out of the dungeon immediately.
Back inside the dungeon, Orun‘s group senses something is terribly wrong. They haven’t encountered a single monster in the massive rooms. When Logan asks if this is normal, Orun admits he has never seen anything like it; it feels as though the monsters are completely terrified and hiding from something.
Frustrated by the lack of action, Caroline carelessly charges at a lone, extremely powerful goblin. Ignoring Orun‘s desperate warning that the monster could instantly kill her, she forces him to secretly debuff it to save her life. After she cheerfully claims the kill, the team scolds her reckless behavior. They point out that without Orun, her impulsiveness would have endangered Sophia and Logan, putting the entire party at risk. Realizing her grave mistake, Caroline sincerely apologizes. Forgiving her, Orun decides to channel her aggressive combat style by offering to teach her a special technique called “active defense.”
Excited, Caroline asks to learn the active defense technique. Orun explains it involves drawing an enemy’s focus to stall them while the team prepares a counterattack. By interrupting a monster’s physical preparation, she can effectively stun-lock it. He emphasizes that her main goal is to stall, not to defeat the enemy alone, which she finally understands.
Meanwhile, on the surface, the hero party meets with the guild master. Luna desperately demands an immediate force-teleport to evacuate everyone in the dungeon. The guild master hesitates because of the massive mana cost, but Luna reveals that the black dragon escaped through the fickle gate to a random floor. Despite the catastrophic danger, the guild master stubbornly insists on following protocol to hold a discussion first.
Back in the dungeon, Logan asks to learn debuff magic. Orun advises against it, explaining that debuffs require memorizing every individual monster’s magic resistance and become practically useless on deeper floors. Instead, he demonstrates how to use pre-laid traps to stop sneak attacks, effortlessly taking out two charging wolves without lifting a finger. He reminds Logan that an enchanter’s real job is maintaining the party’s battlefield advantage. Finally, Orun advises Sophia to learn parallel casting to speed up her powerful but slow special-grade spells.
Orun explains that Sophia can reduce her downtime by parallel casting—starting a second spell halfway through her first. Though he suggests Selma could teach her later, Sophia pleads for Orun to train her instead. Unable to say no to her, he reluctantly agrees.
Meanwhile, on the surface, the force-teleportation spell is finally charging. The guild master orders the hero party to return to the dungeon to slay the black dragon once the evacuation is complete. Aneli nervously makes excuses to avoid the fight, but Luna quickly interrupts and accepts the mission on one condition. As the hero party heads back, Luna explains why she requested floors 40 through 50 be evacuated first: Orun is currently on one of those floors, and they absolutely need his help to win.
Deep in the dungeon, Orun and the supervisors easily defeat a troll boss, flawlessly coordinating to protect the rookies. They eventually reach the 50th floor and defeat the final crab boss, officially completing their expedition. Just as Orun thinks he can finally relax, the space above them shatters, and the terrifying black dragon suddenly drops into the room. Staring down the monstrous beast, Selma, the supervisors, and even Orun are left completely speechless, knowing their current group stands absolutely no chance of surviving against it.
Their only option is to reach the teleportation crystal, but the terrified group is completely frozen in place. Knowing the monster will target the large crowd first, Orun realizes he could easily escape alone, but he firmly refuses to abandon the kids. Choosing to fight to the death, he orders the other supervisors to protect the recruits. They snap out of their daze and raise a defensive barrier just as the dragon unleashes a massive fireball at them. Knowing their basic shield will fail, Orun casts a split-second buff upon impact, saving everyone so flawlessly that only Selma notices his magic.
Seeking an opening, Orun throws a dagger at the dragon’s eye. Anticipating it would blink to protect itself, he uses that brief blind spot to launch a devastating, explosive strike right at its neck. The group is amazed by his sheer physical power, but they quickly panic when the beast emerges completely unharmed. Undeterred, Orun equips a special necklace and charges again. When the dragon fires another blast, he effortlessly deflects it using a custom reflective wall spell. Logan is absolutely stunned to witness this incredibly rare original magic. Unfortunately, even its own reflected fire fails to damage the dragon, forcing Orun to resort to much more drastic measures.
To turn the tide of this impossible battle, Orun casts a powerful status boost spell on himself, effectively doubling the stats of every single one of his core attributes. Watching from the sidelines, Selma remains deeply concerned. She knows that even with his incredible strength, a mere double boost simply won’t be enough to match the overwhelming, destructive power of the black dragon. However, Orun never planned on stopping at just a simple double boost. To the absolute shock of everyone watching, he continuously casts the exact same status boost on himself four additional times, exponentially skyrocketing his physical capabilities to an unbelievable thirty-two times his original power!
Selma watches in utter disbelief. In the world of magic, attempting to repeatedly cast the same buff usually only resets the spell’s duration rather than stacking its effects. She has absolutely no idea how Orun is successfully pulling off such a logic-defying feat, but her instincts tell her that this brilliant enchanter still has plenty of hidden tricks up his sleeve.
Empowered by his massive thirty-two-times multiplier, Orun now moves with such blinding speed that the other supervisors cannot even track his movements with their eyes. Unfortunately, this god-like power comes with a severe price. Maintaining the equivalent of over thirty simultaneous, high-tier spells places an agonizing toll on his physical body. Knowing he cannot sustain this form for long, Orun desperately tries to end the fight quickly, launching himself directly at the towering dragon.
As he flies through the air, the dragon fiercely whips its massive tail to violently swat him out of the sky. Just when it seems he is about to be crushed, Orun miraculously manifests a solid, floating platform right beneath his feet, allowing him to effortlessly leap out of the tail’s destructive path. Astonishingly, this platform is not a standard spell at all. It is the result of his unique innate ability—a rare, natural power that only a select few humans possess. Orun‘s specific talent is “Magical Convergence,” an incredibly versatile ability that allows him to instantly gather raw magical energy into a single, materialized point. By continuously forming these platforms, he can literally propel himself through the empty air, granting him unmatched aerial mobility during combat. Ironically, his former party leader, Oliver, shares this exact same rare ability, though Oliver selfishly focuses his power entirely on brute-forcing his attack strength rather than creative maneuverability.
Taking full advantage of his aerial dominance, Orun casts a rapid series of potent buffs directly onto his sword and dives in for another devastating strike. This time, his blade successfully pierces the dragon’s scales, dealing a significant amount of actual damage to the seemingly invincible beast! Despite the successful hit, the immense, crushing strain of constantly maintaining dozens of stacked buffs begins to visibly catch up with him. Selma watches helplessly as Orun clearly struggles to keep his body from tearing itself apart under the magical pressure. She desperately wants to intervene, but she knows the other supervisors are far too weak to even survive approaching the dragon. Tragically, she also realizes that even if she rushed into the fray herself, her own magical abilities wouldn’t be enough to provide Orun with the meaningful help he truly needs right now.
Though trembling with unprecedented terror, Selma resolves to protect the students so Orun can focus entirely on the battle. Facing the terrifying monster reignites Orun‘s resolve, reminding him of his tragic past. Years ago, he, Luna, and Oliver lived peacefully until bandits completely destroyed their village while the boys were away training. After burying their slaughtered loved ones, the devastated boys swore to gain enough strength to prevent such a tragedy from ever happening again. Driven by this lifelong promise, Orun refuses to let this dragon harm his new friends.
The dragon suddenly surrounds itself with a purple mist, using Magical Convergence to forge weapons for its ultimate attack. However, Orun notices the beast is generating far fewer weapons than the last black dragon he fought, realizing it is underestimating him. He swiftly dodges the initial barrage and uses a fireball distraction to close the distance, but the dragon’s gathered energy has heavily hardened its scales, making them impossible to cut. Pinned down by relentless mana attacks, Orun summons a rock wall for cover, but the intelligent beast seamlessly banks a magical spear right around his shield, leaving him completely exposed and vulnerable.
Fortunately, a pre-cast reflective wall saves Orun from the deadly strike. Watching anxiously, Selma realizes that despite holding his own, Orun still hasn’t landed a decisive blow. Fighting solo is much harder than he expected. Despite his resentment, he admits his old party was highly effective together, and now he must execute all of their roles simultaneously.
Refusing to fail, Orun employs the active defense technique he taught Caroline to disrupt the dragon’s attack patterns and lure it away from the students. Once safely distanced, he unleashes a massive barrage of fire blasts. Knowing standard attacks wouldn’t be enough, he cleverly modified the spells into traps that continuously absorb ambient mana to repeatedly strike the monster. Though the dragon takes heavy damage before finally destroying the magic circles, Orun is ready with his next trick. Mimicking his former leader, he launches his own version of the Divine Slash. When his attack clashes with the dragon’s fireball, Orun perfectly times an impact buff to overpower the flames, driving his slash directly into the beast and triggering a massive explosion.
A severed piece of the dragon crashes to the floor, initially leading everyone to celebrate what looks like a hard-fought victory. However, the celebration is cut incredibly short. The cunning beast is still very much alive, having purposefully sacrificed its own tail to absorb the devastating impact of Orun‘s slash. Realizing he should have expected such a strategic maneuver from a boss-level monster, Orun is forced back on the defensive as the dragon unleashes an even fiercer barrage of fiery blasts.
He scrambles to evade the relentless onslaught, but disaster strikes midway through the chaos: the timer on his stacked buffs completely runs out, instantly reverting his superhuman strength back to normal. Seeing him lose his immense power, Selma desperately attempts to support him by casting her own status buff. Orun, however, immediately cancels her spell. He firmly orders her to stay out of the crossfire and focus entirely on protecting the students, confidently declaring that her buffs simply aren’t strong enough to tip the scales and that he can handle the monster alone. True to his word, he instantly recasts his mind-bending quintuple status boost before striking the dragon with a fully buffed thunder shock spell, blasting the colossal creature completely out of the sky.
Even after violently crashing into the ground, the incredibly resilient dragon simply refuses to die. Orun is running dangerously low on tricks, and to make matters worse, his heavily overworked sword finally reaches its absolute breaking point, shattering into useless pieces in his hands. Knowing the monster is also on its very last legs, Orun discards his broken weapon and decides it is finally time to unleash his ultimate trump card. Activating his “Destruction” spell, he materializes a massive, pure black greatsword—a weapon forged from highly compressed, amplified magic that rivals a special-rank spell, which absolutely no one in the room has ever seen him use before.
Instead of charging head-on for their final clash, Orun continuously bounces himself off dozens of strategically placed reflective walls scattered across the entire battlefield. Gaining blinding, exponential speed with every single ricochet, he launches himself high into the air and delivers a devastating, downward execution strike, finally finishing the black dragon off once and for all.
Meanwhile, back on the surface, the disgraced hero party is rushing toward the dungeon entrance just as the guild’s force-teleportation spell fully activates, pulling every single adventurer safely back to the surface. To their absolute horror, they suddenly find themselves face-to-face with the monstrous black dragon as they approach the entrance. Panic sets in for a brief moment until Luna realizes the terrifying beast is actually just a lifeless corpse that was teleported along with the surviving adventurers. Looking closely at the aftermath, she spots Orun standing victoriously beside the massive carcass, quietly leaning on his sword with the very last of his exhausted strength.
Luna rushes to heal Orun, but he stops her, asking her to handle the cleanup so he can go home and rest. Realizing Orun is the only one injured, Luna concludes he defeated the dragon alone. While this seems unbelievable, Derrick flat-out refuses to accept the facts. Orun ignores Derrick’s provocations, further enraging him. Luna then berates Derrick, calling him a “bum” who will never improve until he admits he is weaker without Orun.
Driven to a rage, Derrick charges at Luna, but she easily freezes him in place. Oliver intervenes to stop the fight, though he still internally refuses to admit he was wrong about Orun. Later, while the group writes their expedition reports, Sophia is excited to document Orun’s brilliance. When an exhausted Selma returns, Sophia suggests they visit the bathhouse together to relax. While soaking, Selma asks for Sophia’s thoughts on Orun. Sophia explains that while his power was unmatched, he essentially performed high-level basics—like active defense and enchantment—at a level so advanced it was difficult to track. She remains amazed that he executed every role perfectly by himself.
Selma is amazed by Sophia’s insight but feels inferior, knowing she cannot match Orun’s power. Sophia reassures Selma of her unwavering respect and urges her not to overextend. The next morning, Orun suffers from the physical toll of his battle with the dragon, though he feels lucky the magical exhaustion isn’t worse. He notices Selma approaching, and they soon meet at a cafe. Selma apologizes for the intrusion, explaining she wanted to ensure he was recovering. Orun appreciates her concern, and Selma formally thanks him, crediting him as the sole reason the expedition had no casualties.
Selma invites Orun to her clan to meet their leader, and he agrees. Upon arrival, the leader offers Orun a position as a frontline attacker for the elite Unit One, along with an immediate promotion to lieutenant. While shocked by such an unprecedented offer for his age, Orun asks for time to deliberate. The leader agrees, but as Orun leaves, he learns the guild leader also requests an audience. Walking there, Orun weighs the tempting offer from the Silver Rabbit Clan but fears a repeat of the betrayal he faced with his former team.
Orun dreads facing his former teammates, but he finds them present during his meeting with the guild master. When Orun confirms he killed the black dragon, Derrick and Aneli scoff, delusionaly claiming they weakened it first. The guild master silences Derrick with a threat of suspension. Orun then confronts Oliver, questioning his reckless decision to take a new enchanter to the 92nd floor. Oliver admits he thought a “superior” enchanter would make the descent easy, proving he still undervalues Orun‘s contributions.
Orun reprimands Oliver for ignoring his past warnings. He explains the immense complexity of an enchanter’s role—tracking individual magic resistances, buff durations, and enemy movements while directing the team. He challenges whether Oliver could ever handle such a burden. Meanwhile, at the Silver Rabbit Clan, Logan, Sophia, and Caroline discuss Orun’s future. They hope he joins their clan so they can spend more time together.
Logan, Sophia, and Caroline decide to ask Orun to join their clan. Meanwhile, Selma reflects on the power gap between her and Orun, fearing she would only hold him back. When the others approach her for his address, she initially hesitates for the same reason. However, the group acknowledges their selfishness, expressing a deep desire to learn from Orun and eventually stand by him as equals. This inspires Selma to bridge the gap herself. She directs them to the guild instead of sharing his private address.
Orun leaves the guild after his statement ensures his former party faces penalties. Spotting the group approaching, he senses trouble and tries to flee. Despite his injuries, he uses mana platforms to reach the rooftops and evade them. He eventually takes refuge in a store owned by an old man, who is baffled to see him hiding. Orun explains he has already decided to reject the Silver Rabbit Clan’s offer and wants to avoid hurting the others’ feelings by saying no directly.
The old man realizes Orun cares for the group since he wants to spare them disappointment. He advises Orun that one betrayal doesn’t mean he must go through life alone. Later that night, Orun retreats to a hilltop to think, where he encounters Sophia. She thanks him for saving them and asks him to join the Silver Rabbits. When Orun asks her thoughts on the clan, Sophia describes it as the place where she truly belongs.
Her words strike a chord, leading Orun to accept the leader’s offer the next morning. Selma provides his official uniform, and the others give him a warm welcome. A flashback reveals that years ago, Orun and Oliver trained together. Orun intentionally lost a duel to Oliver, leading adults to scout Oliver for their own objectives. Oliver, sensing the deception, grew angry, but Orun maintained he was simply outmatched.
A girl named Sion later confronted Orun, calling his “fake losing” terrible. Orun admitted he hid his strength to avoid the crushing expectations of adults, though he felt guilty for shifting that burden onto Oliver. He resolved to support Oliver with everything he had, but Sion yelled at him, insisting he shouldn’t have to carry such a burden alone.
Sion explains that her power is similar to Orun‘s, promising to stand by him so they can achieve their goal. However, Orun‘s memories of Sion remain fragmented, as if parts are missing. Elsewhere, the Grandmaster receives a visit from the Southern Guild Master regarding the black dragon’s defeat. The Grandmaster is shocked, initially assuming Oliver was responsible. When the Guild Master denies this, the Grandmaster becomes unsettled, suspecting Orun despite it seeming impossible.
The Grandmaster questions if Orun has reverted to his “old self,” but the Guild Master reports no such change. This suggests Orun found a new way to attain power, prompting the Grandmaster to order close surveillance on him. Meanwhile, in the eastern region, a group led by Sion slaughters a party of adventurers. As they prepare to move on, Sion senses a messenger from headquarters. He informs them that a warrior powerful enough to slay a dragon has appeared in the south.
Sion deduces that the mysterious warrior cannot be Oliver and prepares to investigate. Her team’s mission is to recruit this individual or, if he has aligned with the Church, eliminate him. Sion notes that the South is Church territory, requiring a stealthy approach. She feels a personal responsibility to intervene, believing she is the only one who can match such power. Driven by a letter falsely claiming Orun died as a child, she blames the Church for his death and seeks vengeance to carry out his supposed will.
In the South, Orun receives commendations for his performance during the dragon incident. The leader highlights his strength, knowledge, and multitasking skills, formally proposing his promotion to lieutenant. This requires a two-thirds majority vote from the current lieutenants. One lieutenant questions Orun, asking if he is willing to sacrifice his life for the clan.
Orun refuses, stating he made a promise long ago that he must live to keep. While the other lieutenants are shocked and question his worthiness, Orun remains firm. He clarifies that his primary motivation is not the clan itself, but protecting the people he cares about.
Orun explains that while he won’t throw his life away for the clan as an entity, he will do everything in his power to keep its people safe. This distinction satisfies the other lieutenants, who approve his promotion. Later, Selma expresses her relief as she escorts him through the halls. Their conversation is interrupted by Estella, the head of personnel management, who requests Orun’s help training new recruits.
Orun expresses concern about balancing teaching with leading Unit One, but Selma reassures him. She notes that unlike the Hero’s party, this clan handles its own administrative work and strictly limits dungeon dives to three days to prevent burnout. Surprised by the healthy work-life balance, Orun agrees to Estella’s request. He then enters the Unit One ready room to meet his new team. The members are eager to work with the famous dragon slayer, and the introductions begin with a woman named Rain.
Despite her appearance, Rain is 24 and insists Orun view her as a big sister, though she remains self-conscious about her stature. Next is 18-year-old Lucrezia, followed by Wilk, the 20-year-old defender. Since Selma is already part of the team, the group moves straight to discussing Orun’s combat abilities. Orun decides to be transparent, explaining his victory over the dragon was due to two original spells: “Impact,” which multiplies weapon effectiveness by 100, and a second spell that boosts his own buffs by 32 times.
The team is stunned by these multipliers, though Orun notes the latter puts extreme stress on his body. When they ask why he doesn’t simply fill every role himself, Orun reveals his primary flaw: he is capped at mid-level magic and cannot cast high-level spells. Fearing they might find him useless, he defends his utility, but the team is unbothered. They reveal that with Orun, the team now has three members with special abilities.
Selma suggests a dungeon dive the following day to demonstrate these powers in action. Orun agrees but mentions his sword was destroyed during the dragon fight. While the others worry about the time needed to forge a replacement, Orun casually explains he simply buys his weapons off the shelf at a local shop.
The group is speechless to learn the dragon slayer uses basic store-bought swords. Refusing to let this continue, they drag Orun to the clan’s dedicated blacksmith, Aaron. While Aaron is willing to forge a custom blade, he lacks the rare materials required for someone of Orun’s caliber. Fortunately, Orun reveals a stash of high-grade materials stored in his magical bracelet from his time with the Hero’s party, which he offers for the task.
Meanwhile, Selma organizes a mission to floor 86 to gather noxious sheep pelts, viewing it as the perfect chance to practice their teamwork. Orun is determined to help this group eventually surpass the Hero’s party record of floor 94. Upon arriving, Selma warns them to stay alert; despite the beautiful scenery, the floor is infested with dangerous earth dragons.
The strategy is set: Wilk and Orun will hold the frontline, Rain will provide offensive magic, and Lucrezia will focus on healing. As the supporter, Selma will manage buffs and commands. Though the team believes Orun could handle the floor alone, he insists on following the formation to build true synergy. Suddenly, a fireball streaks toward them. Orun leaps forward to intercept it with a barrier, realizing an earth dragon is nearby but hidden from view.
Lucrezia’s special ability, magic tracking, allows her to follow residual mana to locate hidden enemies. Within minutes, she finds an earth dragon in the brush and marks it with a flare spell. Wilk rushes in to draw the dragon’s attention, eager to show Orun his skills. While Wilk tanks the beast, Rain prepares a high-speed spell and blows the dragon to smithereens. Orun is impressed by their efficiency; Wilk is a master at canceling attacks, Rain casts at double the normal speed, and Lucrezia’s tracking prevents any surprises.
Under Selma’s leadership, the team functions perfectly. When two more earth dragons appear, Orun and Wilk move to engage, but Orun senses something off. He fires a stone bullet into a patch of grass, revealing a camouflaged turtle trying to sneak up on them. Now surrounded, Selma orders Rain and Lucrezia to handle the turtle while the men focus on the dragons. Orun begins to feel a deep sense of trust in Selma’s tactical judgment.
Suddenly, Orun hears Selma’s voice directly in his mind. She explains this is her special ability, telepathy, which allows for seamless coordination over long distances. Orun is amazed, as he has never encountered such a skill. Flattered by his praise, Selma quickly regains her focus and commands Orun to strike the dragon’s weak spot while Wilk keeps it distracted.
Orun follows Selma’s lead, buffing himself before unleashing an “Impact Slash” that cleaves the dragons’ heads clean off. Simultaneously, Rain and Lucrezia finish off the turtle, allowing the team to advance. Selma asks Orun about his first experience with them, and he admits it was wonderful; after struggling for so long with the Hero’s party, he had forgotten what it felt like to have reliable teammates.
When Selma asks if they are ready for the 92nd floor, Orun confidently confirms they are capable—even without his help. While his praise heartens the group, Selma remains cautious, remembering the dragon’s lethality and refusing to let overconfidence risk their lives. Orun reassures her, promising to support Unit One with everything he has to ensure they reach their goal.
After quickly gathering the noxious sheep pelts—a task made easier by Orun’s expert skinning skills—the group heads back for a welcome party. They thank Orun for choosing them over more prestigious offers, promising he won’t regret it. Orun sincerely replies that he could never regret joining such a team. This moves Lucrezia to tears; she, Wilk, and Rain all admit they feared Orun might look down on them for being weaker. They tease Selma, noting she likely worried the most given her early interest in him.
The others suspect Selma has a crush on Orun due to her fixation on him. Though she embarrassedly denies it, claiming she only wanted him to feel comfortable, she drinks heavily to hide her nerves. A few minutes later, a completely drunk Selma begins making suggestive comments about Orun‘s looks and getting uncomfortably close. Orun turns to Rain for help, but she is equally intoxicated and offers to join in. Wilk and Lucrezia find the situation hilarious, leaving Orun flustered and on the verge of folding. To end the crisis, he casts a sleep spell on both women, feeling relieved yet happy to have had such a fun night.
Later, Sophia worries at home since Selma hasn’t returned from the dungeon. When she hears a knock and recognizes Orun’s voice, she panics, wondering if he came to see her alone. Her disappointment grows when she opens the door to find Orun carrying a sleeping Selma on his back. Orun quickly realizes what Sophia is thinking and assures her nothing happened; Selma simply overdrank at dinner. While relieved that Selma hasn’t “stolen” him, Sophia remains annoyed by how touchy her sister is being with him.
Sophia wakes Selma and sternly orders her off Orun’s back. The sight of Sophia’s anger instantly snaps Selma out of her drunken stupor. Once Orun leaves, Sophia drags her sister onto the bed, demanding an excruciatingly detailed explanation. She is relieved to confirm nothing happened beyond Orun helping her home after the party, but she still warns Selma not to be a burden. Selma apologizes, though Sophia admits it was just a misunderstanding.
While bathing later, Selma reflects on how much more relaxed she has felt since Orun joined. She realizes she must stay composed to avoid getting in the way of Sophia’s clear infatuation with him. However, her very worry about “stealing” Orun suggests she is struggling to accept her own romantic feelings for him. That night, Orun reviews the students’ files, moved by the tragic backstories of Caroline and the others.
The next day, Selma escorts Orun to the management division to begin his training duties. He meets Estella and Carla, the caretaker for new members. Carla is pleased Orun has already studied their files and is willing to train them despite their pasts. Estella informs him there are no rigid training policies; Orun has full creative freedom to teach them based on his own vast experience as an adventurer.
Selma notices Orun is unsure where to begin, so Estella sets a goal: train the recruits to handle the middle floors independently. Though a steep request, Orun believes in their potential and agrees. On their way out, Selma confirms Orun has read the files regarding her complicated history with Sophia. Born to a maid and later adopted into the family, Sophia was treated poorly as an illegitimate child. Selma tried to protect her, but the situation worsened once Selma left to become an adventurer. Eventually, Selma returned to rescue Sophia, and she now asks Orun to help her sister become a truly great adventurer.
Later, the recruits eagerly greet Orun as their new instructor, praising his ability to defeat a dragon with ease. Orun humbly corrects them, noting the battle was a close call. He reminds them that they, too, must one day face such threats if they intend to clear the dungeon. He establishes two ground rules for their training: first, they must think critically at all times rather than blindly following routine; second, they must never assume he is always right. He emphasizes that despite his experience, he is human and prone to mistakes just like them.
Orun encourages them to speak up if they disagree with his instructions. He then asks each recruit their motivation for becoming an adventurer. Sophia goes first, explaining she wants to be like Selma and gain the freedom to live on her own terms, though she is still discovering her specific path.
Logan admits his goal is wealth, but clarifies that he grew up in a village so poor the land was infertile. The villagers pooled their meager resources to send him to the city to pursue his talent, and he now strives to earn enough to repay their kindness. Finally, Caroline claims she has no specific reason other than to “protect people’s smiles,” adding that happy people won’t hit her. Her deadpan delivery hints at deep trauma, which Orun decides not to press for now, simply accepting her answer.
When Sophia asks Orun for his own motivation, he explains his goal is to become strong enough to never lose anyone or anything close to him again. He realized long ago that weakness makes it impossible to protect what matters.
Orun plans to grow so strong that he will never be defeated again. He tells the recruits he won’t coddle them and expects their absolute best during training. Orun then asks Caroline if he can use a nickname to save time during emergencies; she agrees, and he settles on Carol. Logan and Sophia become jealous, leading Orun to dub them Log and Sophie as well.
With introductions and nicknames settled, they head to the dungeon for their first practical session. Carol is tasked with facing a pack of wolves, but Orun grows concerned as she attacks with reckless ferocity. Instead of distracting the monsters like a typical defender, she dives in with dangerous intent. When a second wolf tries to ambush her from behind, Orun intercedes and kills it, warning her to stay aware of her surroundings.
Carol calmly explains she was fully aware of the wolf and had intentionally lured it in. When Orun argues that she could have been seriously hurt, Carol smiles and slashes her own wrist to demonstrate her point. As Orun panics and tries to stop the bleeding, the wound heals instantly. Carol reveals this is her special ability, making her nearly impossible to kill. She admits that while she still feels the pain, she has long since grown used to it.
Carol’s past is harrowing; she was held for years by the Cycloman Church, who exploited her regeneration to resurrect an evil god through gruesome experiments. Though her body remained intact, the ordeal left her mind fractured. Despite rehabilitation, Carol suppresses deep trauma. While Orun initially considers letting her maintain her delusions to spare her pain, he honors his promise to treat the recruits as adults. He directs Carol to look at Logan and Sophia, whose faces are filled with worry.
Carol panics, as her obsession with protecting their smiles is her only way of feeling safe. Orun explains that seeing her intentionally get hurt causes them pain, regardless of how fast she heals. While Carol is indifferent to her own suffering, the realization that she is hurting her friends devastates her. She begs Orun for guidance, and he tells her she must stop self-harming.
Overwhelmed, Carol drops her daggers and apologizes repeatedly, flinching and begging Orun not to hit her—a reflex from the years of abuse she suffered for every mistake. Orun hugs Carol, assuring her she is safe now. Realizing she never actually learned to dodge because she relied solely on her healing, Carol begins a rigorous training simulation designed by Orun to master basic defense.
While Carol focuses on defense, Orun has Log train with a spear to diversify his utility as an enchanter. Meanwhile, Sophie practices parallel processing by counting backward from 1,000 in intervals of seven while maintaining two magic circles. Though overwhelmed, Orun pushes her to stay calm, as her team relies on her focus. In a moment of panic, Sophie releases a wave of raw power that topples a target without a formal spell. Orun suspects this is the manifestation of a special ability, noting her familial connection to Selma.
After several days, Carol can easily dodge multi-directional attacks, Log is proficient with the spear, and Sophie has mastered her mental exercises. They successfully clear the 20th floor alone, though they acknowledge the long road ahead. Orun is then called away to receive his custom sword from Aaron. With a single swing, he knows it is perfect and vows to use it to protect those he cares about.
Testing the blade in live combat, Orun marvels at its handling. Rain points out that its power comes from the dragon scales, but she questions why Aaron added turtle blood, which typically reduces purity. Orun explains it was his idea; while it slightly lowers durability, he can easily compensate by buffing the sword with his magic. The team then asks if he has chosen a name for his new weapon.
Orun reveals he will name his sword Kurofuji, which translates to “Black Rabbit.” He explains the name honors both the blade’s dark color and his new home in the Silver Rabbit clan. With his weapon ready, the team prepares to resume their dungeon conquest. Selma asks if he is available the following day to tackle floor 92, but Orun declines, having already promised to supervise Log, Sophie, and Carol on their own dive. He believes they are ready for the 29th floor, a feat Selma finds impressive for such new recruits, as clearing floor 30 marks the transition to professional status.
Later, Orun visits the old man, who warns him of a dangerous rumor regarding Amon. Orun is visibly shaken; Amon is a notorious organization of adventurer-killers and a major criminal power alongside the Cycloman Church. The old man notes that several high-ranking adventurers have already been killed, suggesting the Guild is suppressing the news to prevent a panic. Though disturbed by the senseless violence, Orun tries to shift his focus to a new project.
Meanwhile, Rain visits a memorial she created for Albert using his bloodstained clothes. She tells his spirit that in three days, they will face the black dragon again, asking for his blessing from heaven. At the same time, Wilk finishes tuning his equipment, determined to ensure nothing holds him back during the upcoming battle.
Aaron looks at Wilk with approval, noting how much stronger he has grown since the days he would have fled from a challenge. Wilk remains haunted by the memory of his own cowardice, which he believes cost Albert his life during their last encounter with the black dragon. He vows never to let that happen again. Meanwhile, Sophie notices Selma staring into the night sky with a worried expression and goes to comfort her. Sophie admits her own nervousness about the upcoming 92nd-floor mission, remembering that the last attempt resulted in a teammate’s death and left Orun in terrible condition. Despite her fear, she offers Selma heartfelt encouragement.
The next day, Orun takes the group into the dungeon, and they easily clear the floor without his assistance. While Orun congratulates them, they credit his guidance for their rapid growth. However, Sophie suddenly realizes that reaching professional status means Orun will no longer be their teacher, and she fears losing her connection to him. She keeps these selfish thoughts to herself as they visit Estella to apply for the floor 30 exam.
Estella informs them that an observer—an independent adventurer tasked with verifying their success—can join them in two days. The kids are confused as to why an observer is needed when they have Orun, but their main concern is the timing: the exam falls on the exact day Orun and Unit One are scheduled for their 92nd-floor mission. Estella explains that due to the observer’s busy schedule, the date cannot be changed.
If the kids don’t take the exam in two days, it will be a long wait for the next opening. Orun offers to ask Selma to delay the floor 92 mission so he can be there, but the trio immediately rejects the idea. Log insists they are capable of handling the 30th floor alone, noting that real adventurers can’t always rely on Orun as a safety net. Realizing they have a point, Orun agrees, provided they submit a detailed tactical plan for his approval.
After reviewing and approving their strategy, Orun surprises them with gifts: three custom necklaces to serve as good luck charms for their safe return. On the day of the mission, Unit One gathers at the dungeon entrance. The kids are also there with their observer; they wave to Orun before both groups head toward their respective goals.
Upon reaching the 30th floor, Log detects approaching footsteps. Sophie suggests a formation where Carol acts as the distraction while she and Log provide magical artillery. As a pack of goblins appears, they execute the plan perfectly. Carol draws their focus with high-speed maneuvers, allowing Log to impale three of them with a “Rock Needle” spell. Sophie finishes the final monster with “Wind Cutter.” The observer is left speechless, having never seen such high-level coordination from a group of rookies.
The kids smile, crediting their growth to their teacher, who has just arrived at the 92nd-floor boss room with Unit One. As they enter, the dragon charges. Selma buffs Wilk, while Orun quadruples his own stats in preparation. Both Orun and Wilk rush the beast to begin the assault.
Meanwhile, the kids reach the 30th-floor boss room, only to find another party waiting. Due to dungeon etiquette, Log politely asks if they can take the boss today. However, upon introducing himself as a Silver Rabbit, he realizes these men are dangerous. The group, members of Amon, is hunting the dragon slayer. When Log refuses to talk, a man named Zuriel uses a special ability to extract the information directly from his mind, discovering that Orun is their instructor. They decide to use the kids as bait.
The observer steps in to protect them but is decapitated before he can react. Terrified, the kids attempt to flee, but the assassins seal the exits with earth magic. Carol tells the others to break through the barrier while she distracts the leader, but she is slammed into a wall with cratering force. The Amon members tell them resistance is futile and promise not to hurt them further if they surrender. With their observer dead and no escape in sight, hopelessness sets in. The kids can only cling to the necklaces Orun gave them and pray for a miracle.
Orun and his team are making progress until his necklace glows, signaling the kids are in mortal danger. This warning device confirms his fears, but he is trapped in a boss fight against a dragon that has suddenly begun regenerating, undoing all their hard work. Time is running out as the kids face their killers.
On the 30th floor, Sophie worries for Carol, but Log reminds her of Carol‘s regeneration. They focus on survival, with Log casting buffs and Sophie firing a “Thunder Arrow” at Geba. Though Geba blocks it, he falls into a rock trap Log set using Orun’s techniques. Enraged, Geba breaks free, pins Log, and prepares a killing blow. In that moment of crisis, Sophie unlocks her special ability: Telekinesis. She flings Geba into a wall, buying time to heal Log.
Geba’s teammates grow impatient, prompting him to vow an immediate end to the fight. Sophie and Log prepare a combined magical defense. Meanwhile, Orun faces a nightmare; the dragon’s new attack patterns are deadlier, and its indefinite regeneration makes a standard victory impossible. Forced to act, Orun unleashes his unfinished secret weapon—Alteration. He shears off the dragon’s leg in one strike, but it heals instantly. Orun realizes the only way to save the kids is to destroy the dragon with a single, absolute blow.
The dragon swings its tail, shattering Selma’s barrier and leaving the group vulnerable to a lethal fire breath attack. With Selma incapacitated, Orun seizes the moment, scaling a nearby cliff to strike from above. He uses Alteration to transform his sword into a spear and delivers a final, crushing blow to the dragon’s head, killing it instantly. Selma is relieved but loses consciousness from her injuries.
On the 30th floor, Sophie and Log are completely overwhelmed. Geba defeats Log and turns his sights on Sophie, intent on eliminating her now that her special ability has manifested. As Geba prepares the killing blow, a sudden sword slash hurls him across the room. Orun emerges from the shadows, apologizing for his delay. He quickly teleports Log and Carol to safety, encasing them in a barrier.
Though the Amon members remain smug—believing their status as human-slaying specialists gives them the advantage in a 3v1—Orun is unfazed by their confidence. He immediately retaliates by casting gravity spells, trapping most of the assassins. Only Sion manages to evade the magical pressure in time, leaving her teammates pinned and vulnerable.
The intense gravity brings the assassins to their knees, and a second later, Orun eliminates them with a lethal lightning strike. Sion is surprised by his speed but remains unfazed. When Orun rushes her, he is shocked to find that despite her small frame, she blocks his full-force strike easily. Even more baffling, she counters with a high-level blizzard spell with zero casting delay.
As Orun leaps back, Sion waves her hand, manifesting another high-rank lightning spell above him without a single chant. Orun barely blocks it with his shield, stunned by her ability to bypass magical incantations entirely. Sion admits she is impressed by his reflexes and invites him to join Amon, but Orun flatly refuses to associate with murderers.
Sion laughs, noting that Orun reminds her of a childhood friend who died years ago. When Orun demands to know her motive for killing adventurers, she cryptically explains that the “original” was defeated and the “replica” has fallen into enemy hands, leaving her no choice. Orun dismisses her vague reasoning, telling her she should simply give up if the situation is truly that dire.
This suggestion sends Sion into a rage. She screams that “overzealous adventurers” like him are bringing the world to destruction by clearing the dungeon. Tired of talk, she ends the conversation by manifesting dozens of explosion spells simultaneously, surrounding Orun with a level of magical firepower he has never faced before.
Orun is quickly overwhelmed, and Sion is confident the explosions finished him. However, as the dust settles, it is revealed that Orun used Alteration to transform his sword into a shield. While Sion stares in shock, he shifts his weapon into a whip to restrain her. Sion is deeply impressed, noting that only her childhood friend could use magic this way. In that moment, she connects the dots and realizes Orun is the friend she thought she had lost.
Orun begins to have flashbacks upon seeing Sion‘s face, feeling he should know her, yet he draws a complete blank. Sion realizes she was tricked into believing Orun was dead by an “old man and woman,” but seeing that Orun has no memory of her, she doesn’t offer an explanation. No longer wishing to fight, she asks for his release. Orun, running low on mana, is forced to retract his whip.
Sion tells him he will understand everything someday. As the other Amon members regain consciousness and Selma’s group arrives, Orun fears more bloodshed. However, Sion decides to withdraw, citing a promise she once made to him. She expresses hope that they won’t be enemies the next time they meet before teleporting herself and her team away. Orun is left confused but relieved his friends are safe—though the observer remains dead. Meanwhile, in the snowy mountains, Sion vents her excitement that Orun is alive, yet she is frustrated that his life as an adventurer may keep them on opposing sides.
Sion is deeply hurt that Orun has no memory of her, but she blames the person who destroyed her home and stole their time together. She vows to make them pay, regardless of the cost. Meanwhile, Oliver works tirelessly to improve his skills, driven by a desperate need to match Orun’s strength. Philly fuels his jealousy by reporting that the public now hails Orun as a hero for defeating the black dragon yet again. To his credit, Oliver refuses to use underhanded tactics, remaining dedicated to surpassing Orun through sheer effort to prove his own worth.
In the guild office, the master is annoyed by Orun’s growing power, especially since the dragon had leveled up. He finds it ironic that Orun now works for him, given their history, and decides to let Orun continue clearing the dungeon while remaining oblivious to the truth. The next day, Orun meets with the kids to discuss the previous day’s trauma. He hopes they realized their own weakness, just as he has.
The kids protest, arguing that Orun cannot be weak since he saved them. However, Orun insists it wasn’t a true victory; if Sion hadn’t chosen to withdraw, everyone—including Selma and Unit One—would have died. He acknowledges that while he surprised the Amon members, he couldn’t have won a sustained fight against their combined strength. For this reason, Orun vows to continue his training, determined to grow strong enough to ensure such a helpless situation never happens again.
