Amazing friends, the sweetest boyfriend and a magic necklace. But, when her body is stolen by her Gehenna form Mayu, she is trapped in her necklace! With the Princess of Insanity attempting to seduce and steal Rin, she will stop at nothing to complete her plans. Even if it means slaughtering Rins' closest friends! Can he see through Mayu's tricks, save his friends, and give you your body back? Without either of you making the ultimate sacrifice?
