Masataka Kiyomizu/Synopsis

Toman Arc
Takemichi Hanagaki and his group went to Shibuya Third Mid, looking for a fight with their second years, but encountered Kiyomasa and other third years. They were easily beaten by Kiyomasa and his men and forced to become soldiers for Tokyo Manji Gang. As part of the fights Kiyomasa was organizing, he made Takemichi fight, but he got knocked out in a single punch, for which Kiyomasa later beat him. Takemichi then said he wanted to meet Manjiro Sano and Tetta Kisaki, hearing Sano's name, Kiyomasa 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 Kiyomasa, slave vs king. Kiyomasa accepted and started beating Takemichi, but Takemichi kept standing up, saying he can't lose and won't run. In the end, Kiyomasa asked for his bat, but the crowd looked disappointed. At that moment, Ken Ryuguji "Draken" came telling him he was losing the audience. Behind him was Mikey and as he approached Kiyomasa, 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 Kiyomasa and asked him if he was the one organizing the matches and Kiyomasa confirmed. Mikey then kicked Kiyomasa in the face, breaking his nose and asking him who he was. As he knocked Kiyomasa, Mikey stopped the matches as they were giving Toman a bad name and dispersed the crowd.

Moebius Arc
On August 3rd, during the Musashi festival, Masataka and his gang plan on taking Ken Ryuguji and someone from Moebius hands him a blade. One of Masataka's guys sees Takemichi and drags him to Masataka, who orders Takemichi to buy them drinks and then starts beating him. After they finish beating him up, Masataka uses duck tape and ties up Takemichi and leaves to look for Ken.

A fight between Moebius and Toman starts. In the brawl, Masataka sneaks on Ken and manages to stab him. As he leaves he mumbles that he did it and Takemichi sees him and rushes to Ken. Takemichi carries Ken elsewhere, where Hinata and Emma tell him they called an ambulance. While waiting for it, Takemichi sees Masataka and his gang approaching. He goes to Masataka and states that he isn't running away and is getting his revenge. Takemichi comments that they haven't finished their one-on-one as he didn't lose. Masataka thinks Takemichi is going crazy, but gets annoyed when Ken, Hinata and Emma bet that Takemichi would win.

Takemichi attempts to punch Masataka, however, he stabs him in the arm, stating that this isn't a one-on-one, but an execution. Takemichi attempts to hit Masataka, but he knocks him back. Takemichi then tackles Masataka and bites him. As Masataka hits him trying to make him let go, Takemichi manage to get on his back and starts chocking him, stating that he may not be like Manjiro, but is Takemichi Hanagaki. As he doesn't let go, Masataka eventually loses consciousness and Takemichi wins. It’s unknown what happened to him afterward, but it’s assumed Masataka lost all respect he had for losing to Takemichi and likely became a outcast.
