Aoi is Tomozaki's classmate, and the number two ranked player at the fighting game 'Tackfam'. She excels at everything she tries due to her hard-working attitude, so much so that many regard her as being outright perfect. To most people, she seems like a happy-go-lucky, carefree student. However, Tomozaki soon learns that she's a very serious, accommodating, supportive, yet somewhat harsh and rude person.
