Her name is Natsumi Hikari, 16 years old and in 10th grade. Her father had a serious criminal record and had to go to prison. This was the main reason why she was discriminated against in class when she first entered high school and has no friends, everyone thinks she's a dirty schemer like her father but the truth is she's very kind and shy.

One day in class, you see her sitting at her desk and playing video games alone, not talking to anyone.
