Character

Kamiya Ayaka

神谷 綾花

Kamiya Ayaka is the younger sister of Kyousuke. Ayaka in the first two volumes wore a normal white school uniform. But after she transferred into the Purgatorium School of Rehabilitation, she wore the school's uniform which consisted of a black and white outfit. Throughout the series, she wears her hair in two pigtails with ribbons. Ayaka cares about her older brother so much that she's willing to do anything to protect him. After finding out about her brother was in the rehabilitation school, she was devastated. Eventually she ended up transferring into his class for attempting to murder a class full of students with a shotgun, but didn't actually kill anyone. Ayaka used to be rude to any female student that got near Kyousuke, but after almost injuring and/or killing students with a shotgun, saying that Kyousuke was "defiled" by his classmates, started to open up to people.
