The eighth sister.

She is a very childish older sister who's more like a younger sister. She is concerned about it and tries to act like an adult and fails. She may look harmless, but can be very moody.

When she is in a good mood, she'll spoil her brother, even going so far as seducing him. When she's in a bad mood she takes it out on him. She's recently learned how to mimic a heart-wrenching cry to garner sympathy.

She has a habit of always wearing pajamas at home
