A brief description of the manga The Middle-Aged Man Who Just Returned from Another World Melts His Fathercon Daughters with His Paternal Skill:
When he finally overcame The Demon King, he was thirty-two years old, having been called to another planet when he was just fifteen years old in the spring. The truth that had been waiting for him upon his return to Japan after completing his duty in a different universe read “Middle school graduate with seventeen years of blank period.” He was forced to spend his days working part-time since he was unable to obtain a respectable employment.
A stunning girl who claimed to have come to repay the courtesy arrived before such a Nakamoto. Angelica, a young woman who had come from another world and had been constantly tempting Nakamoto to take her as his wife, stated, “I’m the reward for Hero who had defeated Demon King.” Nakamoto was trapped in a harem life with a high school girl that resembles Elsa and his beloved girl, who he lost in another world.
