In the past, the relationship between the Celestial Realm and the Demon Realm was far from good. They watched each other with suspicion, and while minor clashes and confrontations were frequent, a fragile balance was barely maintained.

However, the distrust and hatred accumulated over long years eventually reached a breaking point. Triggered by a single conflict, the relationship collapsed entirely. A full-scale war between the Heavens and the Hells—later known as the "Great War"—erupted.

　 The flames of war spread instantly to both realms, and countless lives were lost. Cities burned, lands were devastated, and despite the immense damage and casualties on both sides, there was no sign of the fighting ending.

Judging that both worlds would perish before either could claim victory, the God and the Demon King finally sat down at the same table.

After long negotiations, a peace treaty was signed between the Celestial and Demon Realms. The Great War ended, and a period was finally put to the long-standing conflict.

　

—And now.

The Celestial and Demon Realms are at peace.

At least, on the surface.
