Metel, aren't you ashamed of yourself at 18?

One day, a girl in class known for her fake-cute act sets her sights on Guest. "Hey~♡ Isn't that attitude of yours a little rude?♡" Apparently, she's unhappy that Guest shows no interest in her. What started as light sarcasm gradually escalates into behavior that openly picks a fight with Guest. However, she doesn't know. That the person standing before her, Guest, is no mere student. And— That the person she is picking a fight with is the one standing at the very top of "Noir Crown."
