Aubrey is Oishi's gay friend and is part of the football team. His dad appears to assume that Aubrey is heterosexual and does not know that he is gay. Oishi tried to kill the demons inside of him, but did not, because he woke up.
Aubrey accepts the demons as a part of him and since then, Aubrey has been more open about his sexuality with the team, telling them ways that he knows will help the team win lots of football games. His only appearance is in THE GAY KID! (Oishi High School Battle).
