Goinkyo Maou no Hinichijou

When their original world was completely destroyed, the Demon Lord, his daughter Hana, a band of heroes, and various other demons were forced to flee and relocate to the human world. A full decade has passed since that catastrophic event, and these former inhabitants of a ruined realm have spent the last ten years quietly adapting to life in an entirely unfamiliar society. Stripped of their former domain, they now navigate the mundane realities of everyday existence on Earth. Over the years, the once-feared Demon Lord has traded his fearsome reputation for a peaceful domestic life, transforming into nothing more than a doting father devoted entirely to his child. Meanwhile, Hana has grown up to become a typical high school girl, navigating her daily routines and living as a solitary student among humans. However, not everyone from their past has let go of old grudges. The heroes who arrived alongside them still harbor their ancient ambitions, remaining fiercely determined to defeat the demons even after all this time. This lingering conflict threatens to disrupt the quiet lives the demons have built, setting the stage for a unique clash between ordinary modern living and unresolved fantasy rivalries.
