kou is a cheeky, talkative young man who seems to be very talented according to his flashbacks: in my headcanon he likely loves tattoing and rap music. total gangsta vibez!!!

he has curtained, mid-length brown hair with brown eyes and has black tattoos literally EVERYWHERE. his outfit simply consists of a black leather vest with a tiger backprint, fingerless gloves, military cargo pants and black-white sneakers with zippers.
