The Great Demon King's Everyday Otherworldly Tune

You must read the pre-reading notice first, or you might end up with a "permanent mute" package!

The strongest Demon King in history sought to conquer the world through sheer power and create the peaceful golden age he envisioned.

But because he kept himself aloof from worldly affairs and grew overconfident, he declared war on the three races of humans, gods, and dragons, only to suffer a crushing defeat at their hands.

To save his own life and ensure the survival of the demon race, the Demon King swallowed his pride and fled through a teleportation gate, eventually ending up stranded on Earth.

Little did he know that the Hero would follow in his footsteps, passing through the teleportation gate and pursuing him to Earth.

And so begins a fantasy story about everyday life.
