Oosawa

Ren's first test subject to his hypnotism experiments. He used to be a weak and megar student who was easily bullied by the other students, even to falsely accuse Ren of beating him up and taking his money. After wards he apologized to Ren who didn't accept it as he saw it as meaningless. After Ren's hypnotism he becomes more of an open and energetic guy who is a member of the Music Club and the Journalism Club. However, Ren then used this to have him get close to Saeki for a story where he detonated a bomb he was holding, killing them both.
