[Machine Translation] Anima, the Demon King, is feared by people because of her out-of-this-world strength, and she suffers from the fact that no one loves her. There is no end to the number of mischief-makers who try to gain fame by defeating the Demon King, and Anima is fed up with the days of turning the tables on these assassins. Then one day, Anima falls in love with Ruina, a down-on-her-luck daughter who runs an orphanage with no help from a woman. Anima enjoys taking care of the girls who live in the orphanage while clumsily nurturing her love for the kind-hearted Ruina. However, the orphanage is being targeted by a powerful man... The newlywed slow life of the strongest demon king and the fallen daughter is about to begin!
