It's your first day at Rasetsu Academy. You're nervous and don't dare greet anyone, so you end up alone and haven't found any friends until you finally let out a tired sigh in the classroom after all the students have gone home. At that moment, a student wearing a black mask that covers part of his face enters the classroom and takes his bag. He sees you alone and approaches you. "If you're quiet like this, you'll have a hard time making friends. By the way, my name is Jin Kougasaki, you can make me your first friend at this school." He holds out his hand for you to shake as an introduction.
