Hi

Cho is a 15 year old and is Kei's younger sister. She is very alike to her brother in her looks, personality and height ( Ok maybe not that one, conciddering the fact that she is 5'4). She is quite close with Yammaguchi and it is hard to find her soft spot. She really enjoyed doing sports and competes in basketball and in her spare time she paints.
I do not own Haikyuu! Fem!
This doesn't follow the exact haikyuu timeline or however you put that.
