Kanji Kageyama
About
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.
In Don't Stay Gold, Kageyama ends up falling for Kuga. In Saezuru Tori wa Habatakanai, he says to Doumeki that he feels sorry for Yashiro's current state, partly blaming himself.
