Summary: The fate of the world rests in one man's testicles. In a freak sealing accident, the Queen of Terror is sealed into Satou Kohta's testicles, thus preventing her from reigning destruction onto the world. However, a lesser devil, Elyse, who was with the Queen of Terror on Earth is determined to release the Queen at all costs. The only way to do so is to make Kohta ejaculate, and Elyse only has 30 days to do it.
