Koichi Haimawari vs. Number 6 & Enji Todoroki is a fight between the Vigilante The Crawler and the Villain disguised as the Hero O'Clock II. Shortly after, the Pro Hero Endeavor stop The Crawler, unaware of O'Clock II's presence.

Prologue
In the previous battle, just when Koichi was about to save Kazuho, ​​Number 6 shoots her in the chest with a special bullet containing a drug that makes that makes the Queen Bee and the hive eager to self-destruct. Since the drug takes time to kick in, Number 6 decides to buy time. He meets Koichi in an alley after he rescued Kazuho after being shot. Number 6 intoduce himself to the distrustful vigilante as a hero, and the one who shot Kazuho but assures Koichi that she is fine, calmly stating that he shot her a syringe containing a special drug that controls the bees.

Relieved, Koichi prepares to contact his allies, the "hero" declares that Kazuho had been being manipulated by a villain from the shadows. Number 6 ends his monologue by declaring that Koichi is the villain and he, as the hero O'Clock II, will beat him with his fist of justice. The increasingly suspicious Koichi aks him what's his deal. O'Clock II replies that his speech has two purposes: to clarify to him that every hero needs an arch nemesis is essential, and more importantly, to give the drug time to work and make Pop's bees eager to self-destruct, destroying themselves as well the host.

Koichi watches with unpleasant surprise as the entire swarm of bees leave Kazuho's body. He quickly grabs Kazuho's unconscious body and runs out of the alley.

Battle
Koichi manages to escape the alley with Kazuho in his arms before the first Bomb Bees explode. Using his Slide and Glide, Koichi runs away at full speed through the streets of Naruhata. When he looks back, he sees that the swarm is relentlessly pursuing them, exploding around them in their attempt to blow up Kazuho. To his dismay, Koichi cannot defend himself as his arms are busy holding Kazuho, so his only option is to keep skedaddling and be lucky enough to meet Soga and the others to help them.

Number 6 observes from the top of a building, thinking to himself how Koichi's flashy escape will benefit his debut as the hero O'Clock II. His plan is that when the time comes, he will take down Koichi but he will "tragically fail" to stop Bee☆Pop from blowing herself up. After this "tragedy" he will swear on her wretched soul to never let such a thing happen again. In this way, he will create the “heartbreaking” debut of O’Clock II that will make people instant fans of him.

Number 6 puts aside his fantasies when he sees that Koichi is actually managing to escape, and for his plan to work, he cannot allow that to happen. Using Overclock, Number 6 approaches Koichi and intends to attack him with an explosive punch. Koichi notices Number 6, who compliments him for his fast reflexes, but says that it won't matter since one punch is all it takes to end him. But the villain suddenly realizes he can't catch up with Koichi, and notices that the force fields of Koichi's Slide and Glide Quirk under his feet are changing. Koichi uses his super move Extra Oomph to evade the explosive punch.

Number 6 dust himself off, regenerates his destroyed arm and continues chasing Koichi from behind, displeased that the vigilante is giving him a run from his money in his well devised plan. As Number 6 prepares to strike the Vigilante again, he notices Endeavor up ahead, walking towards them. He had recovered from his cooldown from several minutes prior, and is ready to defeat The Crawler an Bee Pop with his Hellflame.

For Koichi the situation could not be worse: in front of him is Endeavor willing to stop them and the heat he is emitting increases as he approaches; But he can't do anything but move on, since behind him he has a whole swarm of explosive bees and a supposed hero who wants to kill him and Kazuho. Additionally, carrying the unconscious Kazuho limits his maniobrabilidad.

For Number 6 the situation is not yet completely lost. Though he was unable to finish Koichi off before, Endeavor's timely presence gives him another chance to do it. The Number 2 Hero still hasn't noticed his presence, and with him heading off Koichi, the young vigilante would be forced to leave the main street into some alley in order to avoid the flaming hero, decision that he would take advantage of to make his move.

To Number 6's surprise, Koichi neither stops nor swerves, instead, he darts straight towards Endeavor. Seeing that The Crawler has no intention of stopping, Endeavor shoots fireballs at him, which the vigilante dodges as best he can.
