Tsukirou: The Vampire of Karasuno High

This little vampire boy had just enrolled in Karasuno High School as a transfer student and recently joined the Boys' Volleyball Club along with Shoyo Hinata and Tobio Kageyama, but they didn't know about his vampire heritage until much later. Also, the boys of the club thought he was a girl because of his facial features and his long white hair, but only when he speaks is when they've realized their mistake. He tried his best to keep his vampire identity secret, but his abilities during practice, including his bloodthirst, would sometimes get in the way and everyone in the club, including Kensei Ukai and Ittetsu Takeda, the coaches, knows about it. Everyone thought vampires were myths, but this boy is just "living" proof they they're not and are roaming among them to this day. But he doesn't drink blood from the team, not unless they really want to. This boy dreams of becoming one of the first vampires to ever play volleyball in the human public, just like his uncle.
