Toman arc
Mikey and Draken visit the fights organized by Masataka Kiyomizu. Mikey is initially shown to be quite carefree and informal, but upon his reception by the audience becomes more aloof. Despite reactions from the crowd, Mikey does not acknowledge any of them, instead approaching Takemichi Hanagaki. After being introduced, Mikey gives him the nickname of Takemitchy, and decides that from that point onward the two will be friends. Draken and Mikey then break up the ring, declaring that underground fights are not permitted in Touman.

The following day, Mikey and Draken come to Takemichi's classroom. Hearing that Takemichi was being kidnapped, Hinata Tachibana runs after them. Upon meeting Mikey, she slaps him in the face and attempts to leave with Takemichi but is stopped by Draken. Mikey says he is going to kill the two, but Takemichi protests, and asks him to forgive Hinata. Mikey prepares a punch, but then says that he was only joking, and that he would never hurt a girl. Takemichi, Mikey and Draken then leave peacefully, and Hinata apologizes, saying she misunderstood the situation. Mikey accepts, but reprimands her, saying that her actions could've been bad if he was a dangerous person and calls her a nice girl, telling Takemichi to take care of her. The group bikes to a river and Mikey mentions that he likes Takemichi because he reminds him of his older brother of 10 years, who had died. He states that he wishes to create an era of delinquents like the one his brother was a part of, and asks Takemichi to assist him.

Abilities
Mikey is regarded as the strongest member in Toman. His epithet (Invincible Mikey) is indicative of his strength and how he is revered among other delinquent groups. He is strong enough to incapacitate other elite gang members with a single kick and his enemies often comment on how they cannot believe that he is a mere teenager.
