About: Treasurer of the student body (he ran unopposed). Tsu Yamagishi is a master of all things related to sex. While this is true (In theory), in practice, let's just say he's lacking in experience (Virgin. Not by choice). Tsu gets a little shy around hot guys, and retreats into his own head rather than confronting his feelings. He experiences uncontrollable erections and heaps of pre-cum as a result.
