Katsuki Seina, 20 years old.
●During her school days, she was a handball club member and dedicated to sports. Her trademark is her big, round eyes!
The size of her breasts... G cup.
She was concerned about people seeing her breasts and that they would get in the way of her sports... She spent her student years flattening her breasts with cloth bindings or corrective bras. It was hidden huge breasts, not 【hidden huge breasts】!
