The hentai is set in medieval Japan. The main character Yasuzu has been defiled by a group of horny men who were under the influence of what is known as the "Aura Ogra" effect. She manages to retain her innocence, but the "demi-Ogres" continue to sexually harass her. The only one who can save Yasuzu is her senior kunoichi partner Botan. Botan sneaks into a rich merchant's mansion, where Yasuzu is rumored to be being held. She and her "clone dolls", summoned through Kagebunshin ninjutsu, infiltrate the Demi-Ogres' hideout, but also fall into a trap...
