Isekai Kaeri no Ossan wa, Fusei Sukiru de Fathercon Musume-tachi o Tororori ni vol. 1

The Middle-aged Man Who Just Returned From Another World Melts His Fathercon Daughters With His Paternal Skill
After being summoned to a different world in his youth and returning
victorious in battle against The Demon King at age thirty-two, he faced a
harsh truth upon coming back to Japan. Despite graduating middle
school, he had an unaccounted for period of seventeen years. Job
opportunities proved futile, and so he took up part-time work. Enter
Angelica, who claimed to be his "completion bonus" and relentlessly
pursued becoming his wife as compensation for his heroic deeds.
Combining his cheat skills with his situation, he found himself in a
harem-like situation with Angelica and a high school girl who resembled
Elsa, his lost love from the other world.
