But after she transferred into the Purgatorium School of Rehabilitation, she wore the school's uniform which consisted of a black and white outfit.

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.
