The hero, having defeated the Demon Lord and brought peace to the world, was riding high! She dealt with the remaining remnants of the demon army with ease. "My level might not go up anymore, but I'll keep working for the world!" Lately, however, the hero has been having strange dreams. They are nightmares where the invincible hero is defeated by demons and subjected to their whims. Even knowing it's a dream, the pleasure she feels—in her chest, her private parts, all over her body—is so realistic that it wears down the hero's spirit. Then, the source of the nightmare appears. By the time she realizes the truth, it's too late. Her body, imprinted with pleasure, has no way to resist. A hero whose level is maxed out, experiencing these nightmares every night. The pleasure she feels—in her chest, her private parts, all over her body— Is it a dream or reality? With each awakening, the hero's spirit is worn down.
