Toman Arc
One of Pah-chin bud's got beaten badly and his girlfriend raped by Moebius leader, Nobutaka Osanai, which caused a conflict with Tokyo Manji Gang.

Pah-chin and Peh-yan are at the Musashi Shrine for Toman's meeting. As they see Takemichi Hanagaki, they get angry at him for what happened with Masataka Kiyomizu. Takashi Mitsuya tells them they were told to drop it, but Pah-chin explains he is stupid and doesn't understand it. Ken Ryuguji then yells then to shut up and they leave Takemichi. Manjiro Sano asks Pah-chin what he wants to do. Pah-chin is aware that if they fight, Toman won't go unscathed, but he is really pissed and wish to fight and kill them. Mikey knew he would say that. He asks everyone if they are scared or think its too much trouble to fight for his bud, but everyone just grins. Mikey then yells they are gonna crush Moebius on August 3rd, the Musashi Festival.

Moebius Arc
During a meeting between Mikey, Ken, Pah-chin and Peh-yan, Takemichi comes and asks Mikey to call off the fight with Moebius, stating that someone is plotting the fight, but he can't tell him how he knows. Pah-chin then pushes Takemichi aside warning him that he will kill him if he says anything else. Takemichi keeps insisting its a trap, which annoys Pah-chin and he starts hitting him. Mikey states that they are going to fight Moebius as he made up his mind already. As Takemichi states he won't back down, Ken stops Pah-chin, stating that maybe they need to look more into Moebius. Mikey then wonders if Ken is against Toman. Osanai then shows up and states they should respect as he is two years older, which makes Pah-chin angry and he rushes at him, but Osanai knocks him with a punch and jokes that they need to rename to Middle School Baby Alliance. Osanai comments that he heard they are picking a fight with them and that he decided to bring the fight to them and calls the rest of the Moebius, who surround the Toman members.

Osanai starts hitting Takemichi as he felt he was looking down on him. Pah-chin stops him and decides to take him on, but ends up with a broken nose and is easily defeated. He apologizes to Mikey for being worthless, but Mikey states he didn't lose. Mikey then goes to Osanai and knocks him out with a single kick. A moment later Osanai got up and attacked Mikey, but Draken neutralizes him. While holding him, police sirens wail and everyone decide to run, however in that moment Pah-chin stabs Osanai in the back as he didn't want him to get off that easily. Pah-chin tells them to leave as he intends to turns himself in. Osanai survives and Pah-chin is sentenced for a year.
