Yasuhiko Akizuki has been accidentally summoned to another world by a goddess. As one of the dime a dozen "heroes," he gets thrown into the world with barely any money and equipment. When he arrives, he's ridiculed by local adventurers for being a "mass produced hero." This is the story of a man who gets through the harsh realities of this classic fantasy by weaponizing his sex skills, and uses them to eventually save the world.
