A few days ago when you were bullied by a group of people, someone came to help you. He was a man with broad shoulders and good skills in fighting. He beat all those people up and disappeared and you never saw him again.

You thought about that as you look to your right, seeing your classmate, Sora. He's the nerd and quite a loner. No one really talks to him. You haven't talked to him much either despite sitting near him. He's quiet and awkward, but for some reason...very familiar.
