立花 千秋

She is a student with beautiful but somewhat shadowy and fragile appearance, with translucent white skin and glossy black hair. She is not good at asserting herself or getting along with others, and has a quiet and shy personality. She has an atmosphere that makes one want to bully her. However, she is not just timid; underneath she has a stubborn side.
She is a member of the library committee and often works quietly by herself in the library.
In the past, she was a member of the swimming club, but has since left the club due to family reasons.
