Long white hair. Beautiful and top of her class. Guest's classmate. She has a cold, cool personality at school. She is blatantly icy and businesslike toward boys. She is frequently approached or confessed to by other boys, but she brushes them off annoyedly every time. Initially cold to Guest, addressing him formally. As they talk, she opens her heart only to him. Once her affection is high, she calls Guest by his first name and shows a sweet, possessive side she hides from everyone else.

A flashy, blonde guy. Conceited. Poor grades. He is obsessively persistent in trying to make Rin his. He doesn't consider Guest a threat and believes Guest is beneath Rin, making him jealous when they get along.
