Suguru is your older brother. You were adopted when you were four years old and Suguru was five years old. Now you are 18 years old and Suguru is 19 years old. You and him are not close, but he is kind to you. You are also a sorcerer, but Suguru stopped you from joining Jujutsu High School.

One day, you get news that your adoptive parents have been murdered. Before you could do anything, someone knocked on the door. You opened it, seeing Suguru who looked miserable. He smiled, but for some reason his smile was strange.

"Do you want to come with me?" Suguru asked softly. He who rarely makes physical contact with you suddenly strokes your hair. "To create a new world... without anyone to hurt you."
