Koichi Haimawari, Shota Aizawa, the Hotta Brothers & Kirihito Kamachi vs. Octoid

Prologue
After discovering a new skill with his Quirk, Koichi goes out to patrol, as he usually does. On this occasion, Kazuho can not help her because she is busy with school matters. For his part, Aizawa investigates the traffic of Trigger, going to the store of the Hotta brothers to see if he can obtain information from the black market.

Battle
During his patrol, Koichi is directly with Octoid, a Next-Level villain with a Cephalopod-like Quirk. At first, Koichi tries to stop him, but because he did not have any support and Octoid’s enormous strength, he decides to warn people to run away while he tries to distract him as he can, while waiting for the authorities to arrive. Koichi tries to stay at a safe distance from the Villain, but soon he is forced to escape when Octoid begins to throw rocks at him with enormous force.

In his escape, he arrives near the Recycle Shop Hoppers, where Aizawa and Jiro and Ichiro Hotta are. One of the stones thrown by octoid breaks the window and causes damage inside the store, which puts the three on guard. When Koichi goes to warn them to take cover, is face to face with Aizawa, and both recognize each other from the struggle that Aizawa had with Knuckleduster several months ago.

Before Shota can ask him anything, they hear a scream. Octoid had decided to attack a couple of girls, but is stopped by Aizawa. The hero uses his Erase Quirk in him but checks that it does not work, so he deduces that Octoid is another of the subjects modified by the Villain Factory. Aizawa uses his capturing weapon to hold him, and when he thinks that he has already subdued him,, at that moment Octoid pulls two tentacles from his torso and attacks Aizawa with them, leaving him severely wounded.

When the villain was about to finish him, Koichi comes up to him and shoots him a repulsion beam, saving Aziawa. Then, the Hotta brothers transform themselves by injecting a legal version of Trigger and decide to help him too. Their attacks do not seem to have much effect on Octoid, so Aizawa advises to take him to an area where there are no civilians. One of Hotta Brother suggests taking him to their warehouse, where only Kirihito is. Everyone goes to the place while Koichi keeps shooting Octoid to attract his attention and make him chase them.

Kirihito is peaceful in the warehouse, enjoying a cup of tea and listening music. Jiro Hotta suddenly arrives and suggests him to leave, but Kirihito admonishes him for invading his privacy without being announced. Then the other three arrive, and with them Octoid, which causes great destruction in the place. This makes Kirihito mad and attacks the villain. However, Octoid is too strong for him.

Aizawa and the Hottas intervene to distract him, while Koichi throws a Crawler's SGB to him that does nothing but piss off Octoid even more. But while he is chasing Koichi, Aizawa uses his capturing weapon as a net and captures Octoid. Thinking that they already had him captured, Kirihito has a new fight with Octoid, releasing him by accident and collapsing the warehouse. Octoid decides to take advantage of the confusion to run away. The others go after him.

Aftermath
In his escape, Octoid meets O'Clock's pupil in an alley, who defeats him easily using his Quirk, and extracts a blood sample from his body. When he was about to leave, Octoid throws him a stone that causes a slight scratch on his face, but that greatly angers O'Clock's pupil, who gives him a brutal beating.

When O'Clock's pupil was ready to finish him, Koichi arrives at the place, which forces him to leave Octoid very badly wounded, who is then locked up by the police. The next morning, Tsunaguchi interrogates Aziawa questions about the villain, while wondering who has been responsible for leaving Octoid in such bad shape.
