Battles & Events

Iwao Oguro vs. Kuin Hachisuka is a fight between the Vigilante Knuckleduster and the Villain Factory member Kuin Hachisuka.

Prologue

After having news about the Naruhata Festival, a performance at the roof of Marukane Department Store with local artist and some guest heroes, Kuin Hachisuka thinks that she should unleash a surprise villain on the show. To do this, she decides to use Teruo Unagisawa, now transformed into a Next-Level Villain.

Kuin intends to inject Trigger into the confused attendees.

The night of the show, Kuin starts her plan and releases Teruo in the streets, causing panic among the passers-by. Attracted by the screams, Eraser Head appears and tries to stop Teruo. During the battle, Teruo unleash a large blast of electricity with his Quirk. The surge of electricity causes a blackout in the surrounding area, including the show on top of the department store.

Kuin sits atop a nearby roof, watching the events. She thinks about pumping Trigger into the panicking audience at the show. However, a mysterious voice in her earpiece advises against it, because that kind of actions doesn't square with their cost and they can not risk losing their test subject, but Kuin plays down.

Knuckleduster faces Kuin.

Suddenly, Kuin hears a voice behind her. It's Knuckleduster, who had been on her trail the last few days. The Vigilante approaches her as he puts on his Taser Knuckle. He then calls her Tamao, and tells her to come home to her mother.

Confused by Knuckleduster's words, Kuin tells him that he has the wrong girl, but Knuckleduster clarifies that he doesn't want to talk to the "bee user", but rather his daughter, Tamao. Kuin only laughs hysterically as Knuckleduster rushes towards her with his Taser Knuckles.

Battle

Kuin dodges Knuckleduster's punches.

At first, Kuin thinks that Knuckleduster will not dare to attack her with his characteristic brass knuckles, since she occupies the body of his daughter, and that is why he has the Taser Knuckle, to defeat her without damaging Tamao's body too much. However, this turns out to be wrong.

Knuckleduster swings and Kuin dodges by moving to the side at the last moment. However, she barely dodged a second swing from Knuckleduster's second bare fist. Knuckleduster reveals that actually he hopes not to strike her with the Taser Knuckle, because it would kill her.

Kuin tries to blast Knuckleduster with her Bomb Bees.

Kuin sends out a cloud of worker bees to Knuckleduster, and one of them explodes besides him. Kuin laugh, explaining how these bees are special Bomb Bees. The cloud of Bomb Bees fly towards Knuckleduster and explode. However, deduces that only the first Bomb Bee was the only real one, while the rest were only bluffs, so he continues to attack Kuin.

Kuin is backed into a corner, and she jumps off the roof and escapes into the streets. Knuckleduster uses his grappling hook to pursue her. During the pursuit, he receives a call from the hospital informing him of the worsening health condition of his wife. He responds that soon the whole family will be there soon. as he runs towards Kuin.

Knuckleduster chases after the bee user.

In the street below, Eraser Head sits down next to a defeated Teruo Unagisawa. Shota notices a bee with a syringe plunged into Teruo. He notices how it was sucking something from Teruo's body and tries to smack it with his bonds, but the bee flies away.

Back to Knuckleduster, he corners Kuin into an alleyway. Multiple bees inject Trigger in her, making Kuin's mission no longer the priority, and prioritizing the feelings of the host: Tamao Oguro. Her nails become sharper, almost like claws. Tamao thinks back to her past, and how she had frequent issues with her father. She yells at Knuckleduster to stop pissing her off. He pulls out his taser knuckle.

Kuin stops Knuckleduster's heart.

The bee that Eraser Head tried to smack appears and pumps Teruo's sample into Kuin's body as she dashes towards the masked vigilante, giving her an electric power. She plunges the claws of her right hand into the old man's heart, and gives him a strong electric shock to his heart.

Thinking that she finally killed Knuckleduster, Kuin continues with her plan to crash the Narufest party. At the Marukane store's roof, the power is restored, and the show will begin. Kuin sees this and decides that she's going to go and crash the event.

Knuckleduster defeats Kuin.

Out of the darkness, to Kuin's surprise, Knuckleduster emerges. After getting shocked, he used his Taser Knuckle to defibrillate himself. Losing patience for the situation, Kuin says that she will sacrifice the body she is currently using to kill him, then move on to the next one. She then rushes towards her opponent with a swarm of genuine Bomb Bees, and enough voltage to fry her own body.

Knuckleduster notices that she is not bluffing this time, and the blowback of her assault will kill the host body: his daughter Tamao. Knuckleduster jumps up and swings at Kuin with his Taser Knuckle, but misses. Kuin tries to impale him with her electric claws, but Knuckleduster manages to dodge her attack and punches her. Then, Knuckleduster ends the fight by hitting her in the chest with his Taser Knuckle, defeating her.

Aftermath

Knuckleduster extracts the bee parasite from his daughter's body.

Kuin falls to the floor, cursing Knucklesduster. He tells her that by stopping his daughter's heart, the blood flow to her brain would stop, and that her body is already dead, and the only way she could survive would be to shock her heart with her claws, but he doesn't let her.

With the death of Tamao's body, a massive swarm of bees evacuate her body through her left eye. Using a small device, Knuckleduster extracts the bloody pulp of the queen bee, the real Kuin, from the hollow hole of her eye, and calls back the swarm with a pheromone cocktail attached to a bomb device. The device explodes, killing the Queen Bee and the swarm.

Knuckleduster performing CPR on his daughter Tamao.

With the death of the bees, Knuckleduster then proceeds to perform CPR on his daughter. He manages to resuscitate Tamao and save her, taking her to the hospital where his wife is hospitalized.

On the street below the department store, the police handcuff Teruo. Naomasa Tsukauchi approaches Eraser Head to interrogate him about the situation. Eraser Head tells Naomasa that he doesn't think Teruo is an Instant Villain, and while he didn't see any injector on him, he did spot a bee on the villain. Naomasa mentions that many civilians mentioned getting stung by a bee during the mass outbreak of Instant Villains.

"The many, reduced to one."

Near them, what appears to be a policeman walks down the street, playing with a small plastic capsule in the air, and singing to himself. He notices the last of Kuin's bees shakily flying through the air past him. In a flash, he jumps up and catches the bee in his capsule. Then, the mysterious man leaves the place.
