High school girl Inazuma. A gentle girl and the kindest among the sisters. The milk she drank to grow taller didn't really give any visible result. But in exchange for not growing taller, she has the curviest body among the sisters. This fact made Akatsuki, who also didn't grow taller, look at her with jealousy.

She has a serious personality, but because of her low capacity, her results are not that good.

Because she can't refuse the requests of others, she is part of various committees and club activities despite not having anything she's especially good at.
