Masataka Kiyomizu

Masataka Kiyomizu or Kiyomasa (キヨマサ, Kiyomasa) was the boss of the Shibuya Third Mid school and member of Touman. He was organizing fights but was shut down by Mikey.

Appearance
Kiyomasa is a relatively muscular teenager whose prominent feature is a scar upon his left eyebrow. He has black hair that is stylized in a small pompadour. He wears Shibuya's uniform, which is a dress shirt, black slacks, and loafers. He is also shown to smoke.

Personality
Kiyomasa is a merciless and cruel individual, who brutalizes those he considers below him. He is not hesitant at all to assert his dominance upon the weak and use them to fulfill his pleasure and means.

He is also shown with a vengeful streak, as seen when he gets manipulated into attempting to stab Draken to death out of spite for humiliating him earlier.

Touman 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 Touman a bad name and dispersed the crowd.
