Хідака Субару

A second-year student in the same school as Kaito and Akiho. He won the Robo-One championship several years ago and as a result Akiho tries to get him to joint the robotics club, but he refuses because his father got him to promise he'd stop playing with robots in high school and become a fisherman after graduating. Kaito blackmails him into joining the club with Mr. Pleiades' identity.
