This manga takes place in a fantasy world and is about a Demon Lord who marries the hero’s mother and tries to live happily together.
One day, the hero in a fantasy world attacks the evil Demon Lord, only to be crushingly defeated. Bored with the battle, The Demon Lord decides to spare the hero’s life and return her back to her home village. When the Demon Lord gets there, he falls in love at first sight with the hero’s mother (whose husband is deceased) and the two immediately get married. Now, the Demon Lord, the hero’s mom and the hero must find a way to live together and to live happily.
This is mostly a slice of life and a comedy. There are some sort of serious plot beats and a little bit that deals with the politics in a medieval fantasy world, but it’s mostly just an overprotective step dad trying to get along with his new step daughter.
Overall, it’s a nice little story that was boring in a few places. I still enjoyed it as I can’t recall reading another story similar to the premise in this one.
