</PRE></noinclude>Kōichi Kameda is a very talented baseball player who was first mentioned in Onikakushi-hen, and appears for the first time in Tatarigoroshi-hen. Keiichi who uncovered his perverted side (comparing girls with cute desserts) advised him to confront it. After this, Keiichi becomes his idol and friend.

He used to be a player of the Okinomiya Titans baseball team, but later he became a Koshien player for Ōshima High School. In Minagoroshi-hen, he helped to save Satoko from her uncle with all of his comrades from Angel Mort.

Kameda has shaved black hair, dark eyes, and freckles on his face. When he plays baseball, he wears a white shirt, as usual, and sometimes a white cap. A green collar, short T-shirt, blue pants, and black shoes are his usual attire.
