Kuroshi Megumi is cursed! Long ago, Megumi's ancestor, the notorious thief called "Kuronekomaru" or the Black Cat, broke into the house of the Kougami family and stole a family scroll. When he opened up the scroll, the family's protector god rose out of it and cursed Kuronekomaru and all his descendents! Though why should it matter when all of the Kougami family is dead? Or so he thought until one day the Kuroshi's receive a letter informing them of the survival of the heir to the Kougami fortune.
