Asu Yamada

Asu is the younger sister. She does the shopping for the family and also takes care of the cooking and cleaning. Asu is extremely fond of her big sister and tries to do everything she can to make life easier for her, since she is as yet too young to work for money herself. Asu is quite skilled; she has been chosen as class representative and is frequently consulted by her classmates when they have trouble with their homework. She claims to be tone-deaf, but manages to sing after some tutoring from neighbour Masao.
