Mizuno Chihiro Born on January 23, and have a "O" blood type. Is a first year at Kouryo High School. Is unable to control his urges and got erect very easily.
Because of his constant tardiness, he was sent to participate in the re-development system together with two other problematic senpai, Takatou Shinobu and Kandori Akira. Sharing a room with Takatou, Mizuno got erected when he helped Takatou (a mangaka) on his smutty works. Takatou tried his best to help Mizuno, but fell in love with Mizuno along the way.
