Wakatsuki Yuno♀

The protagonist’s childhood friend. Possessing excellent motor skills, she has the ability to compete in national tournaments for rhythmic sports gymnastics. She is something of an idol at school for having a Swedish mother and an extraordinary figure, but she is actually a masochistic introvert who will do whatever good people tell her to. She is affectionate towards the protagonist since he doesn’t make a fuss over her appearance.
