The Black Cat & the Vampire, Volume 1

There's a rumor flying around all-boys boarding school Blanc College: someone has been attacked by a vampire! Quiet and studious Yuki Hasegawa has little interest in these rumors until he realizes that student council president, Jean Michel, is behaving suspiciously... But no matter how closely he investigates, Jean doesn't seem to have any of the traits of a vampire. The rumors eventually die down until the night of a grand, multi-school ball, when a terrible accident promises to change Yuki and Jean's lives forever.
