In ancient times, against the Demon Lord Big Marler, who sought to conquer the world, chosen girls became magical warriors and confronted him. Amidst the fierce battle, magical warriors fell one after another. However, "Magical Warrior Sakura," the last one remaining, mustered her strength and annihilated the Demon Lord.

Now that peace has returned, Sakura was living a happy life as an ordinary married woman, "Sakura Uzaki." But the Demon Lord was not destroyed. He had regenerated his weakened body, patiently waiting for the time of his revenge. To protect her happy family with her husband, Sakura fights while enduring the regenerated Demon Lord's obscene ploys. However, her comrades are no more. She no longer possesses the power of her prime. The magical warrior costume, meant for a young girl, now only obscenely emphasizes the ripe body of a married woman. In the living room, in the kitchen, in the bedroom—the married woman magical warrior has no choice but to succumb to the hell of pleasure from tentacles that suddenly attack her.
