The cement space creaks like wood, a gale of wind amplified by an electrical current creating a column of air that does the opposite of supporting the underground infrastructure. Sweeping through the tunnel is pure power channeled through a One For All generated blow. All Might's successor stands with his fist raised, a spitting image of the hero, albeit the cape added to his costume billowing an extra personal touch. He just blasted away another member of Chisaki's Eight Bullets, this one a criminal capable of covering his body in crystal. The diamond armor wasn't enough to withstand the sheer strength of Mirio's punch though. The hard layer shattered on impact, and the ensuing wind gust carried the Yakuza's unconscious body down the hall.

When Mirio lowers his arm to see past his own fist, his yellow visor allows him to see a second enemy coming through the smoke clearing his attack created. This one also wears a plague mask, though the small beak doesn't quite match the man's behemoth body. A hulking figure of solid muscle that could rival All Might and Endeavor combined in a bodybuilding competition stomps forward. Thew as thick as the Yakuza's skin stretches the material of his tank top. Mirio raises a single brow; this guy looks like he can take a hit better than the last few villains. The bulkish brute brings his fists together, metal gauntlets igniting sparks when the knuckledusters collide with eachother.

Mirio moves first, channeling another kinetic charge of One For All throughout his body. When he invades the villain's space, he brings his fist up into the goliath's stomach. He can tell by the way that the Yakuza hunches over, his hit knocks the man's wind out of him. But the criminal is quick to recover, retaliating by wrapping his colossal arms around Mirio while they're still close together. He squeezes, constricting his bulky biceps so that they crush the young hero. If Mirio weren't countering with his own strength, he'd surely have gotten a few bones broken to say the least. The two struggle in a brief grapple against their shows of force. While wrestling though, the performance between each opponent soon becomes a little more challenging for All Might's successor.

Mirio feels his energy dwindling, and not just because of how much of it he's exerting to challenge the Yakuza. The young hero recalls his mentor's reports; this is another member of Chisaki's Eight Bullets, Rikiya Katsukame, and he has a quirk that helps him siphon stamina from anyone that he touches. So long as he stays locked in this stalemate of strength, he's going to have all of his power drained from him. Mirio calls upon his original quirk, before receiving One For All, and phases free from Katsukame's vice grip. The goliath is left hugging himself when the blonde backs away to catch his breath. They pause, but then … Mirio gasps when he realizes that the energy he had sapped from him was added to his enemy's supply; Katsukame has somehow gotten bigger.

The Yakuza heaves a hefty left at Mirio, forcing the young hero to duck down and dodge. Mirio darts between the hulk's legs, using the space between them to regain some leverage in their fight. "You're a big guy but I'll bet you still skip leg day like the rest of us!", he knows Nighteye would have appreciated that quip as he brings an elbow down on Katsukame's calf. The villain grunts, bristling against the blow, but his knees don't buckle. "Okay … Maybe you don't skip–", Mirio has to reconsider his evaluation of the brute when he's nearly backhanded by a meaty arm. All Might's successor slides back, somewhat startled by his enemy's display of power.

Katsukame swings two giant fists at Mirio, making the young hero swerve to avoid being struck by them. The blonde counters with a strike to the Yakuza's side, eliciting another groan from the villain. But Mirio doesn't stop there. He pushes to slam into the behemoth again and again. Blow after blow, Katsukame starts shifting slowly to a kneeling position. Mirio breathes a sigh of relief, seeing that he's making some headway. That is, until the Yakuza makes a wild grab for the young hero and gets his grubby mitts on him. Mirio fights the hold his enemy has on him before using permeation to slip through the villain's fingers. Except, by then, Mirio is much too late. Katsukame has already siphoned off another bout of energy.

Mirio steps back in, delivering a strike to the brute's solar plexus. While Katsukame does budge, he's still able to retaliate with his own punch. "Ha!", the behemoth boasts when he sends the young hero flying through the air. Mirio tumbles across the tunnel a bit before stopping his roll by planting his hands into the ground. He shakes his head, trying to shake off the hit. At least, with a gap between them now, the blonde sees he has a runway for a supercharged attack. One For All courses through his system, just a little more than he typically uses. His legs prime themselves before he pushes off. Mirio's cape flaps behind him as he flies forwards. Katsukame barely braces for impact when they collide with one another.

A rush of airforce plows down the hall, pressure accumulating into their tackle until they're rocketing like a bullet. Smashing through a couple layers of cement walls with unprecedented speed is jarring to say the least. The two dispel from eachother as they continue their destructive journey within the Yakuza's maze. What brings the crashing mess of fumbling fighting to a stop is Katsukame slamming into a sprawled starfish shape. Mirio lands on top of the behemoth's belly, also winded from the battle. Rubble rushes down around them, a trail of debris and dust still settling. The young hero's coughs indicate he's still conscious while the villain's silent sleeping indicates unconsciousness; the victor has been decided.

Except, when Mirio pushes himself over the Yakuza's body to land on the ground, he doesn't feel very victorious. The room where he winded up isn't an empty one. Kai Chisaki himself is seated across the way, looking none too pleased. And right across from the young head of the Yakuza is who Mirio can only presume must be the leader of the League Of Villains. All Might's successor stands on his feet, brushing himself off from the grime of his entrance. It looks like things are only getting started here. Mirio cracks his neck side to side, preparing for another bout of battling a tough enemy or two. There's still some One For All left in him to go around, pure power crackling as it starts to regenerate itself.

Chisaki pushes himself up from his seat to challenge Mirio's stance with his own. "You've really made a mess of things…", he grumbles behind his beak shaped mask but it's difficult to tell who he's referring to when his gaze is cast down instead of at either Mirio or his fellow villain. He picks at the edges of his wrists, a gesture Mirio can only interpret as meaning trouble will occur when the man's gloves come off.

The blue haired villain beside him begins backing away, seemingly sensing some of that same danger. Mirio tenses when purple fog surrounds the League Leader. "Maybe … but nobody likes a neat freak", it's not until it's too late that Mirio realizes that dark smoke is a warpgate to help the man escape. All Might's Successor returns his focus to Chisaki, not willing to let another bad guy go if he can help it.

Chisaki sighs, sliding one of his gloves off. "Like I said … Such a mess", and much to Mirio's credit – nothing can prepare him for what happens after that.


The trio of Nighteye, Centipeder, and Bubble Girl come to an abrupt halt. Their trip through the Yakuza's underground tunnels has led them to what one might consider a dead end. An open space lit with a chandelier is occupied by villains playing poker around a wood table. Most of the men are wearing masks befitting of plague doctors but there are others who break that mold like one with a burlap sack over their head. One with a bowler hat stands up to greet the heroes, "Well … What do we have here? Some uninvited guests?"

"I wasn't aware there were invites", Bubble Girl swallows a lump in her throat while trying to ease the tension of the situation with a joke. She anxiously glances between her boss and her fellow sidekick, sweat dripping down her forehead.

Centipeder plays along, "I suppose that makes us party crashers then", hoping to quell some of the girl's nerves while simultaneously hiding his own. He finds himself gazing at his boss too, seeking instruction from the hero.

"In that case…", Nighteye carefully gauges the Yakuza that outnumber him and his sidekicks with a calculative stare. It's not like retreat is much of an option. He pulls his tie loose to let his neck breathe a bit. And then cracks his knuckles. "Let's crash us a party."

The room may as well becomes a disorienting dance floor. Suddenly dizzy, the three heroes stumble with misplaced footing. A man in a mask fitted with drains leaks alcohol from its eyeholes as he jumps into action, "Sure! Come join us! There's plenty of booze to go around!", he carries with him a bottle that sloshes just as much beer.

A round of miniature projectiles plow into the drunken Yakuza. They're hyper density metallic seals, practically shurikens, and they shatter the villain's mask along with his bones. Even with his accuracy somewhat off kilter, Nighteye still managed to get his aim right. The Yakuza's quirk had been what was dizzying the heroes, its effects wearing off now that the man is down. "Get them", Nighteye stops the funny business and gets to work.

"I've got the little one!", Bubble Girl leaps for a shorter Yakuza in a black jumpsuit. She wraps the villain in a hug, clinging to him so that he doesn't wriggle free. But it turns out that the small stature was merely a disguise to fool her. A muscular arm bigger than both of her own put together bursts loose from the Yakuza's leather onesie to grab the girl's throat. She's hoisted into the air as she's choked, "Okay – Maybe I don't!"

"Bubble Girl!", Centipeder shifts his focus to his colleague when he sees her in trouble. But he currently has problems of his own, too busy to rescue her. A blonde Yakuza hacks at the sidekick with a katana, forcing Centipeder to dodge and swerve in the direction opposite to his ally. "Hang on!", Centipeder cries out in desperation as he tries to push past his opponent.

But Nighteye is already coming to Bubble Girl's aid, driving a foot into her assailant's beaked face. "Don't be distracted from your own fights!", he warns his sidekicks to stay on their guard before dodging an attack from the burlap baddie. The scarecrow villain snaps at Nighteye, nearly biting the hero's head off.

"R- Right!", Bubble Girl rubs the sore spot around her neck as she tries to recover and return to the battle. No doubt, regardless of her already blue pigmented skin, that's gonna leave a bruise. She returns the favor by punching the jerk that gave her that mark. His neck twists with the blow despite his now revealed muscular form.

Centipeder dodges another swing from his enemy's sword. The sidekick's insectoid arms elongate, winding to wrap the villain up. But the Yakuza foresees his capture, retaliating with a swift strike of his blade. Centipeder cries out as his arms are chopped off. Bubble Girl pauses to check on him, screaming with horror of her own when she sees his dismemberment. Nighteye spares a glance but doesn't waver when he's rushed by the scarecrow villain again; the hero instead demonstrates his grief with an angry blow to the burlap baddie's face.

"Enough of this!", the bowler hat Yakuza draws a handgun. A deafening crack of a bullet leaving its barrel echoes throughout the underground hall. Bubble Girl's brains blow out the back of her head as she's shot down. Her body hits the floor the way a paint bucket would clatter and spill. Nighteye utters a noise of distress but is forced to push his feelings aside when the Yakuza redirects their pistol on him.

Nighteye grabs for the blonde villain with the katana, using the Yakuza as a human shield as gunfire rains down on him. Their bodies topple over from the recoil of the shots. Which leaves the armless Centipeder to charge the bowler hat villain in a last ditch effort to shift the tides back in the hero's favor. Unfortunately, there's just enough bullets left in the Yakuza's pistol to gun down Centipeder too.

"What a mess they made…", the Yakuza grumbles as he lowers the smoking pistol. He's just about to turn and head out for reinforcements when he sees the corpse of his fallen ally wobbling. Nighteye tosses the body he used as a shield off of himself, covered in blood from the gunshots but none of which is his own. "Ah, damn…" The remaining Yakuza faces the remaining hero.

It's a race between who can reload their gun before the other stands up. Then it's a race between who can reach the other first, bullet or fist. Nighteye's knuckles scrape the villain's masked face as he's shot through the shoulder. They both take a spill, falling to the floor. The Yakuza's weapon clatters as it carries itself away from the two fighters. Nighteye throws another punch that shatters a lens on the villain's plague doctor mask. They roll over, landing on top of eachother.

Nighteye screams as the villain digs a thumb into his bullet wound. The hero grabs at the Yakuza's face, gripping it firmly as he drives his own thumb through the eyehole he broke and into the man's socket. Blood curdling shouts reverberate throughout the chamber as they both wrestle against one another. Nighteye drives a fist into the Yakuza's stomach. The Yakuza throws a punch into the hero's mouth.

Nighteye tumbles when he's thrown from the villain. The Yakuza got the best of him. He chokes on his own blood, but levels his blurry gaze on the villain ever still. When the hero's vision focuses on the gun that he landed next to instead, he swallows some of the copper taste in his mouth. Nighteye grabs the pistol and raises it up. It may be a second of hesitation or a second of setting the gun straight for accuracy, but it's after that second that Nighteye pulls the trigger and kills the Yakuza.

Nighteye's hand trembles, but his grip on the gun remains firm. He's surrounded by bodies and blood. Two of which are his sidekicks. Unsure of how he can call himself a hero with that being the case, he releases a roar of anguish. This whole operation was his idea and he knows that if he hadn't rushed it, if he had waited for the proper reinforcements, that maybe things would have gone differently. Overcome with guilt, the man folds over and breaks down in despair.


A whirlwind of blades clashing shatters a wall of cement, Chainsaw Man and Katana Man flying from tunnel to tunnel. The flow from which they move carries a continuous momentum, one that keeps them airborne so long as they propel from hallway to hallway. Corridor after corridor combusts when they collide with each wall. Pebbles pelt Izuku when he braces against a katana with an arm bar. The boy flings his other chainsaw limb upwards to scrape against his opponent's headmounted sword. They twist with cutting motions before breaking apart.

"What's the matter? I thought you were gonna cut me down!", Izuku goads his enemy as he prepares a trap. A trick he's been honing that proved easier to pull off when in enclosed spaces like alleys or hallways comes in clutch. He unlatches the chains from his arm bars so that they spiral out and ensnare his doppleganger.

A wave of nausea hits Izuku, right before the katana creature cuts itself free with a flex of its bladed arms. That rush of an unease, though weaker, felt familiar. When Katana Man crouches to take a form that also seems similar to another swordsman he fought, it clicks. That was bloodlust. This is a Nomu version of, "Stain?!", Izuku chokes on his own gasp of shock when the modified hero killer slashes through his stomach.

Innards spill out of Izuku's gut, his torso nearly torn in two. He staggers while maintaining the fading feeling of his consciousness. His fingers fidget as they twitch towards his ignition cord. Stain turns back towards the boy, reassuming his same posture that comes before a deadly dash. "C- Come on.. Let's ban that move", Izuku can't pull his starter string without a set of digits. His hand flies off with the rest of his arm, severed from his body.

Izuku drops to his knees, vision blurring as he begins to blink out the hall's dim light. He's running out of time to reach for his ripcord. He still has his other hand. Except, he doesn't. When he tries grabbing at his sternum, he can't feel either arm anymore. Katana Man must have come back and cut off the other limb while he was falling down. There's not much hope left for him when Stain crosses his blades to make a scissor formation at the boy's throat.

Izuku kicks out, sweeping his leg as a Hail Mary, a chainsaw bursting forth to slice at Stain's knees. Katana Man trips thanks to the sneak attack, letting Izuku keep his head a while longer. Long enough to reach for his starter string with his tongue. A blade swoops up and detaches the boy's elongated tongue before it can make contact. Izuku spits out saliva coupled with blood, surprised that what had quickly been becoming a signature move was disrupted.

Katana Man sits across from Chainsaw Man, both of them staring as they seep blood into a collective puddle. The brief break is over. Stain swings a bladed arm at Izuku, forcing the boy to roll out of the way. A clammer of steel against stone echoes when the sword misses. Izuku lays on his back, breathing becoming ragged; the floor isn't so hard, it's quite comfortable enough to fall asleep on actually. He shakes his head, waking himself up. He can't lose consciousness. Not yet. He tries using his chin to snag the handle of his starter string, hoping the metal point will be enough to catch it.

A katana slides straight through Izuku's chest. Followed by another. The boy yells to express his pain when the blades hoist his skewered body up. It's clear to him now that Stain had been holding back when they had their first fight, when the hero killer was in his right mind. Now that Stain has been genetically modified into a monster though, as a Nomu, those self imposed limits have been removed. Katana Man is the real deal and Chainsaw Man hadn't been prepared for it. He's about to die.

Katana Man slides a katana out from Izuku's chest, eliciting more than just an agonized grunt. The blade draws back, readying to spear the boy through his skull next. But just as he prepares to deliver the finishing blow, Stain gets disrupted. A pebble pelts the back of the Nomu's head. Katana Man stops short. Briefly, Izuku hopes the rock is somehow enough to defeat the villain the same way that brick during their first fight had. But he knows that's more than wishful thinking. The pebble serves simply as a distraction. Katana Man releases Izuku, the boy's body sliding off his bladed arm and hitting the floor. Before turning to face who dare cast stones at him.

The little girl that the Yakuza has been holding captive trembles under the monster's looming form. Izuku opens his mouth but barely an exhale escapes as he struggles to simply breathe. He can't warn her. He can't yell at her to run. His dismembered body refuses to move, a state of paralysis overcoming him as fatigue sets in. He's forced to lay there on the filthy floor and watch as a monster of his own design steps towards the girl to slay her. Or maybe he spoke too soon. His vision is getting darker. Too dark to see. Maybe he'll die first.

The Yakuza's prisoner backpedals, preparing to flee when she sees nobody will be coming to her rescue. Except, her bare feet aren't bandaged like the rest of her body, and those exposed soles step on sharp shards of stone. She falls, shouting. Katana Man towers over the child, blades shimmering under the dark tunnel's dim lighting. The girl squeezes her eyes shut, bracing for the familiar sensation of pain she's experienced too many times before. When death doesn't come, she slowly reopens them. A wisp of purple smoke billows between her and the bladed beast.

Out from the plume of purple pigmentation, emerges the League Of Villains leader. Shigaraki surveys the scene, disregarding the child with a scoff but then spotting Izuku Midoriya's corpse. The blue haired fiend steps a little closer to the young hero's body, red eyes marveling at what his creation managed to do. "Well done", his scarred lips curve into a smirk, "Very well done" He nudges Izuku's limp form with his foot, checking to see if the boy is truly dead. When he confirms that the kid is a goner, he gestures for what's proven to be a superior pet to follow him back through Kurogiri's warpgate. "Now that we're finished here, let's go home."

Katana Man obediently walks with his creator through the portal. Then, as quickly as the villains had arrived before the little girl's eyes, they vanish without a trace. She's left alone with the boy who had been sliced and diced to little less than pieces. The girl gradually crawls towards the body, sniffling as she fights back tears. He had looked scary but she saw how he stopped the beaked man who always hurt her. She thinks maybe this boy isn't as bad as the bladed monster or any of those other guys.

Her hands hover above him, wavering as she tries to discern what to do. Her quirk, even though the doctors tell her it's a disease, has helped heal and revive like Chisaki's. He told her to stop or else she'd be hurt as punishment but she remembers she was able to do it. Maybe there's a way to reverse the damage to the boy. Her eyes widen, noticing something interesting. She sees a string swaying from his chest. He's turned over, the wire dangling. She doesn't have anything like that on her. Maybe… She taps the top of her head, where a small horn is. Maybe that string is like her horn.

She grabs the tiny handle with her equally small sized hands and pulls.
