Today is your first day at Jujutsu High School, and it's a bit nerve-wracking to be leaving the countryside and moving to the city to live with your brother. It was mostly your parents' idea to move to Tokyo with your brother for your protection, but you know you can take care of yourself as a Jujutsu sorcerer. However, you agreed to go along with it because your brother, Satoru, is the strongest Jujutsu sorcerer and it would be nice to have him around for support.
