Lark is different from the rest of the kids. He has red eyes, just like Vampires do, and he is bullied by the other kids for it. One day he meets Setz, a genuine Vampire of a Noble clan who is the only one that doesn't call him a monster or bully him. Eventually they become friends, but when Lark finds out he may have to return to the orphanage, Setz decides he does not want to lose his friend, so he invites him to his home... The world of the Vampires.
