Tatsuhiko Mimura

Mimura went to the same high school as Taichi and used to bully him. In the present day, he is still rich and engaged to Megumi, the most popular girl at their high school. [Spoiler] After Megumi is murdered, Mimura says he doesn't plan on supporting her mother as he "has no such obligations". He is also relieved to hear that Megumi hadn't been sexually assaulted and had died a virgin, specifically because it meant she "had had no other guys before [him]". [/Spoiler]
