Toman arc
Takemichi Hanagaki and his group went to Shibuya Third Mid, looking for a fight with their second years, but encountered Masataka and other third years. They were easily beaten by Masataka and his men and forced to become soldiers for Tokyo Manji Gang. As part of the fights Masataka was organizing, he made Takemichi fight, but he got knocked out in a single punch, for which Masataka later beat him. Takemichi then said he wanted to meet Manjiro Sano and Tetta Kisaki, hearing Sano's name, Masataka took his bat and beat even more Takemichi, warning him to never mention that name again or he will kill him.

While another member of Takemichi's group had to fight, Takemichi proposed he fight against Masataka, slave vs king. Masataka accepted and started beating Takemichi, but Takemichi kept standing up, saying he can't lose and won't run. In the end, Masataka asked for his bat, but the crowd looked disappointed. At that moment, Ken Ryuuguji "Draken" came telling him he was losing the audience. Behind him was Mikey and as he approached Masataka, he bowed to him, but then got kicked by Draken, telling him he needs to bow more when he greets Mikey. After Mikey spoke with Takemichi, he went to Masataka and asked him if he was the one organizing the matches and Masataka confirmed. Mikey then kicked Masataka in the face, breaking his nose and asking him who he was. As he knocked Masataka, Mikey stopped the matches as they were giving Toman a bad name and dispersed the crowd.
