Keita Wakui
Keita is a student in Osaka High and is a member of his school’s boxing club. Keita is unfriendly and doesn’t like to get close with others, being a lone wolf by choice. Even though he typically ignores cries for help, he usually assists others anyway using his amazing strength to accomplish tasks by his lonesome. He is obsessed with getting stronger, noted by how he is constantly training on his punching bag or how he has a thick rivalry with strong opponents.
In the third episode, he saves both Hibiki and Io in exchange of his own life.
