Description

Oldest sister and the present landlady of the mansion.
She is near-sighted and needs glasses to see clearly; in addition, she has no sense of direction. Ai is a motherly figure who constantly tries to help people. Her easygoing, caring nature often leads her to fail at things because she cannot muster the resolve to criticize others. This is why she allows Chris to stay with them when she finds out he has nowhere else to go.
Believing she is ugly and fat, Ai hides herself behind her glasses and by wearing large, loose-fitting clothes. She also seems to be the de facto caretaker of her sisters' pet ferret, Unagi, which often hides under her hat. Ai also loves to take baths, more than once a day if possible. Ai has the ability to speak to plants.
