Nakamoto Keisuke, once the most powerful Hero, was summoned to another world at fifteen and spent seventeen years there before returning to Japan at thirty-two. Upon his return, he found himself labeled as a middle school graduate with a blank period in his life, making it difficult to find stable work. He begins working part-time until a girl named Angelica appears, claiming to be a reward for his past heroics and insisting he marry her. She is joined by a high school girl resembling the woman he lost in the other world. Nakamoto, possessing powerful skills from his previous life, becomes entangled in a harem situation with these two women.
