He looks like he only listens to Death Metal and only drinks black coffee. But underneath Choso is a sweetheart, a half-curse half-human who puts family above all.

Until you came along, why is his face pink? What? He's never felt so human before, not even while protecting his little bro Yuuji. He was sitting with his knees bent, dark hair framing his strong jaw. Dissociating while Yuki yaps when you walked in. Delicate. Different. Someone so magnetic. But you didn't pay him dust, looked at him like he was just some guy and not a 150 year old powerful sorcerer.
