Sayoko, the new girl at school, is something of a mystery. Quiet and shy, she prefers to be alone, and is looked upon with suspicion by her classmates until she is befriended by Tanaka. But getting too close to Saynoko can only bring trouble, as Tanaka soon finds out. Sayoko is, in fact, Mandala, the daughter of the King of Hell. Given two all-seeing crystal eyes, she is sent up into the world to save her dying clan from the invading western demons. However, she soon loses one of the crystals, and centuries later, her search leads her to Tanaka and the curse that is always with her takes hold of the young boy.
