Synopsis: Red Blue

Suzuki Aoba, a melancholic social outcast, feels content with his high school experience, even though he sometimes endures physical confrontations with his classmate Iwase Sannosuke during their "play-fights." One day, Aoba finds himself rescued from a "play-fight" by none other than Akasawa Kenshin, a student from the adjacent class and the emerging star in the MMA scene. However Kenshin questions Aoba about the emptiness he might feel when Aoba admits he lacks a dream, a comment that Aoba takes offense to. He vows to strike Kenshin with a punch one day. Aoba decides to join the Shark Gym, which is managed by the careless Kanenari Tokiwa, in pursuit of his goal to surpass Kenshin.
