Yamashina is the fourth guy to let Hiyoki stay in his room. He's a cool and collected second year that is very organized. This being showed in his room. He has arrows that are on the floor and he asks Hiyoki if she could uses them instead of walking in her own direction. He is the Treasurer of the student council. There seems to be some tension between Yamashina and Cain, because Yamashina lives in S-Hall.
