Toman arc
Mikey along with Draken visited the fights organized by Masataka Miyomizu. Upon seeing them, everyone bowed and greeted Mikey. One of Masataka's men, Akaishi, tried talking to Mikey, but he was ignored and Draken explained that Mikey don't talk to people that doesn't interest him. Mikey passed by Masataka, while Draken kicked him, telling him he needs to bow more. Mikey then faced Takemichi Hanagaki and asked for his name, but started calling mi Takemitchy. Mikey wondered if he was really a middle schooler and then said that from now on, he was his pal. He then beat Masataka and stopped the fights he was organizing.

On the next day, Mikey with Draken came to Takemichi's classroom and took him with them, while beating some guys in the corridors. Overhearing that Takemichi was being kidnapped, Hinata Tachibana faced Mikey and slapped him and then grabbed Takemichi's hand and tried to leave, but Draken stopped them. Seeing the situation Takemichi stopped Draken and told him to release Hinata. Mikey then told Takemichi to prepare himself to die, as it was a shame as they couldn't have been friends and Takemichi accepted, but wanted Mikey to not lay a finger on Hinata. As Mikey was about to punch Takemichi, he stopped and told him, he was just joking and he won't hit a girl. Then they left peacefully with Takemichi, but outside Hinata came and apologized to Mikey, who told her that it was nice to stood up for her boyfriend, but needs to not overdo it, as it would have been bad if he was dangerous person. Mikey and the rest then went near the river, where Mikey told Takemichi he reminds him of his brother, and wanted to make a new age of delinquents and wanted Takemichi to join him.
