亀田 幸一

Kameda Yukikazu 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.
