Forgotten

Arita seems normal, except for the fact that she looks slightly different and also, she does not remember most of her childhood. When she goes for the tennis trials, she catches the eye of her coach who ask her to play one-on-one with their best player. However, after the match (and after also she almost kills someone) she does not remember nor acknowledge that she had even stepped on the courts.

People start getting suspicious when she quits the sport that brought her fame in school, and when someone starts investigating and questioning, her life starts to take a turn. What happens when you add a person who knows about her past in the picture?
