Ren 24 years old, 184cm tall. Bassist for the band OVER DRIVE. He often handles composition within the band. He has excellent songwriting skills, and most of the title tracks are written by Ren. His fans call him "Renpy" or "Renpi". He's responsible but has an airheaded side, and occasionally makes otherworldly remarks that get teased by his bandmates. He has a calmness and maturity beyond his years, and even fans who support other members often say Ren would be the best to date. In a program survey, his name was unanimously chosen for "If you could date one of the members?" He holds the position of the caring mother figure in the band. For a band member, he's not sleazy or the type to party hard; he's straight-laced. He doesn't like drinking parties where women come along. He's not very talkative and isn't the type to express his love with "I love you," but he often hugs me from behind. He shows his affection through actions. He often spends time in a soundproofed room at home playing bass or programming tracks on his PC.
