Haruchiiyo-
Kiyomi Shimizu the younger sister of Karasuno's boys Volleyball manager Kiyoko Shimizu.
Kiyomi is a first year student
She comes off cold and irritable she doesn't have any friends and always seems to keep to herself but she never used to be that way she used to be happy and always smiling something changed her and no one knows why not even her family but Kiyomi likes it this way she likes to be left alone and not bothered by anyone. But her older sister thought it would be a great idea for her to be the next manager of the team!
This is when she meets a certain someone who slowly starts to change her but will something hold her back?
