Higuchi Mana

"Is it ok if i call you Onii-chan?"

The younger sister of Hayato's badly-mannered friend.

When their father transferred and their mother followed him, the siblings live alone in the same housing complex as Hayato.

Perhaps because of her silly older brother, she grew up to be a reliable person, so she takes care of not only her brother but also Hayato, who is without parents.

The more she sees her sloppy older brother, the more she admires Hayato, who is independent, and she has a slight crush on him.

However, while she is keeping a close eye on the current housing complex wife commotion, she has decided to act as an oasis for him when he gets tired of their aggressive advances.

She likes baths and takes them often, so she always smells of shampoo.

Although she is annoyed with her brother, she does not abandon him, and she knows her place as a younger sister, so she is a kind girl who never uses violence or nasty remarks.
