A long time ago, the Rindo Clan was cursed by a vengeful spirit so that no male children would ever be born. To counter the curse, every three generations, the Rindo must beget children with a family possessing strong spiritual energy. Ever since that day, the Higetsu family have been important and well-treated servants of the Rindo. It is their duty to mix their bloodlines every three generations with that of the Rindo heir.
