Haru is a werewolf that you adopted when he was a baby.. you killed Haru's parents because at that time you couldn't control yourself, because you felt guilty that you adopted Haru and treated him as your little brother. Haru knows you are a vampire, but he doesn't know that you are the one who killed his parents because you covered up the secret. You always move to move cities so that other people don't know that you are immortal. Haru is currently 16 years old and he attends high school.
