Prologue
During the Naruhata Bombing, Koichi managed to rescue Kazuho, ​​preventing her from being killed by Number 6 and neutralized by Endeavor. With the help of Midnight, Soga and her friends, they manage to convince Endeavor to take the unconscious Kazuho to a hospital. However, the villain Number 6 swears to Koichi that as soon as she recovers from her injuries, he will kill her first and then him.

In the hospital they manage to extract the queen bee that she controlled from Kazuho's head, although she remains unconscious for days. Due to the threat from Number 6, Soga and his friends Moyuru and Rapt decide to stand guard at the entrance of the hospital inspecting any suspect who wants to enter, while Koichi is camped on a nearby roof, also vigilante in case Number 6 decides Appear.

Because of her connection to Kazuho, ​​and because he had to face heroes for rescuing her from her. Koichi is also wanted by the police. The situation gets complicated when Number 6 attacks the police station destroying all documents and evidence about his past, leaving Detective Eizo Tanuma in very bad condition. Now in charge of the operation, Detective Naomasa knows that the attack on the station was a plot to hinder the Naruhata Investigation. He later receives an arrest warrant against Koichi and plans to use this opportunity to shut down the Naruhata Vigilantes for good.

Naomasa and the police show up at the hospital, demanding Soga and his budies to cooperate and let the policemen take charge of Kazuho's protection. Soga’s willing to hand over watching the hospital, but he does not hesitate to tell him that he doubts that they are capable to handle the situation. Midnight tries to mediate but Naomasa interferes and talked about the arrest warrant for Koichi, a.k.a. The Crawler, and commands Soga to call him.

Soga does so, telling Moyuru to give Koichi a “wake-up call”, that is a coded message to tell Koichi that there's an emergency and he should run and hide, which he does. Then Soga suddenly bolt from the area and Naomasa and several police officers immediately pursue him, reducing the number of members in charge of guarding the hospital. Midnight criticizes Naomasa for his hasty decision, while he calls the Team Idaten to take charge of capturing Koichi.

Battle
Koichi passed the city at full speed, sliding and glinding between buildings, reaching the highway where he is almost run over by a car. He manages to shake off the police’s pursuits, but to do so he strays too far from the hospital, so he decided to sneak back without being caught.

However, the Turbo Hero: Ingenium managed to catch up with Koichi, ordering him to slow down. Shocked, Koichi accelerates to get away, but Ingenium catches up with him again, telling him that he knows what's going on and he just wants to talk with him, but for this he has to halt. Koichi unleashes his Quirk and stops himself by sticking to a moving truck to listen what he has to say to him. Ingenium tells him he knows that he’s in danger, but he and his crew can protect him and Pop.

Having been informed by Soga that Number 6 could be infiltrated, Koichi knows he cannot agree to Ingenium request, so he decides to assure him that he will hand himself to the police after Kazuho has recovered, but for now he can’t as he blasts away apologizing to him, sneaking through Naruhata alleys to evade Ingenium. Nevertheless, the Turbo Hero had foreseen this, so he deployed all of his sidekicks through the alleys, and prepared a trap for Koichi. Enigma, Onemu Shinya, Bigshot and almost the entire Team Idaten crew corner Koichi, ready to capture him. But Koichi keeps on escaping using his Quirk to blasts up into the sky.

The team members apologize to Ingenium for failing, as he orders them to expand the perimeter and focus on pursuit. Upon seeing Koichi gliding smoothly and at high speed along the walls of the buildings, Ingenium notes that thanks to Koichi's new found versatility, he may be too much for Team Idaten to handle, so he decides to leave the job to other heroes.

While he is in mid-air, Koichi is attacked from behind by a Spiral Spear Hand, forcing him to land on the rooftops. Koichi is surprised to known that the one who had attacked him was Edgeshot, and next to him is Best Jeanist, and they are ready to capture him. Best Jeanist reveals to Kocihi that they know that a villain is after the life of Pop and that he tries to protect her by himself. However, with his actions he is indicating that he doesn’t trust the efficacy of the heroes. So they want to win back the trust in the Pros that he supposedly doubts.

Koichi realizes Best Jeanist's intentions and tries to retreat but the hero is faster and unleashes his Fiber Master Quirk to bind the jacket Koichi was wearing over him to become a straitjacket. Desperate, despite being bound Koichi uses his Quirk to slide away and jump off the rooftop. Best Jeanist and Edgeshot quickly use their Quirks and stop Koichi from falling. Best Jeanist unleashes his Super Move Catching Cradle and creates a web of threads to prevent Koichi from falling to the ground. At the same time, Edgeshot releases Fishhook Snag and catches Koichi. But that made the garments that restrain Koichi loosened up for few seconds. Koichi took those seconds to his advantage and free himself from the bind and slink away.

Both Best Jeanist and Edgeshot are amazed that Koichi managed to escape from their hands. The Fiber Hero confesses that they have misjudged Koichi's sheer resolve, to which the Ninja Hero addsthat capturing without injuries a desperate opponent that doesn't prioritize his own wellbeingis a challenge. Best Jeanist accepted that they have failed to prove their worth and to capture The Crawler. But as Pro-Heroes, there is no room for excuses in the work, and they both head to pursuit him.

The hours go by and it starts to get dark, and during that time Koichi had managed to evade his pursuers as he rushes towards to the hospital through the Naruhata alleyways. But then he is confronted by a mysterious person, who says the surface dwellers are not equipped for people like him, but Naruhata alleyways are his hunting grounds. Koichi asks who he is, and the mysterious man turns out to be Eraser Head.
