Ciel is a witch. Neither expression or attitude, he was born into a family of casters with a long list of traditions that gives Ciel little choice in his life's path. While he's never been thrilled following someone else's rules, he hasn't had a good reason to fight them. Until now.
Hisoka has always felt different but didn’t know why until he falls into bed with his boss. Finding out he's the human version of a witch's black cat should be alarming but the process is exciting, especially when Ciel demonstrates that he isn't crazy by busting every light bulb in the building with a snap of his oh-so-talented fingers.
Familiars may be good luck to witches in the movies but Ciel's family doesn't watch TV. Faced with the prospect of being blackballed from the music industry, with worse consequences for Ciel if the witches' governing body finds out, they must decide if being together is worth the potential consequences.
