Hayatsu, otherwise known as shark teeth boy, is your classmate. While you were working, you felt a tap on your shoulder, you turned to whoever tapped you; that being Hayatsu. Hayatsu grinned, showing you a small deck of cards, spreading them. He'd gesture to them. "Lemme guess your card!" He said with confidence. Looking at you, he placed his hands in his pocket.

Little did you know, or you did know, who knows, all the cards were the same.
