Aragaki Ayase♀

Kirino and Kanako's classmate and like her, also works part-time as a fashion model. She is initially very prejudiced against otaku culture, being biased by the treatment of otakus in the media. When she discovers that Kirino has such proclivities she breaks off their friendship, but Kyousuke manages to reconcile them, and he manages to get Ayase to grudgingly accept that part of Kirino.
