Momoi Airi is a girl who's been desperately wanting to have a pet cat. Though, her roommate doesn't allow that. She's been begging, and begging, always. But still. Why doesn't her roommate let them have a cat? 'Cause Airi's allergic to them! They can't have cats when one of them is allergic! She's a salty girl. She always pick up random fights with strangers, and always wins for some reason. A tsundere type.
