About Maou (demon lord); his daughter, Hana; and the heroes. They and others demons transferred to human world after their own world destroyed. It is the story 10 years since they came to demon world. The maou now is just a doting father, Hana become a lone high school girl, and the heroes, they are still wanting to beat the demons
