Kanji Kageyama is a heavy-handed doctor with a fetish for burns and scars. He's been friends with Yashiro since high-school and is Yashiro's love interest. After graduation, he went into medical school and then ran his own clinic following his parents' footsteps. He's a passive, reserved, but tolerant person. In high school, he often helped Yashiro with his injuries. Even after Yashiro showed Kageyama his twisted side, Kageyama still decided to stay with Yashiro until graduation.
