The Demon King Died, and the Hero's Companions Burst Into Tears

[Memory Reveal + Western Fantasy Setting + Anime]

The Demon King’s army was wiped out, and the four great generals under his command were all slain by the hero’s party.

Led by the hero’s party, the allied races marched on the Demon King’s castle to face the now-lonely Demon King, Sisyphus, in a final battle.

After the hero’s companions defeated the Demon King, the "Heaven and Earth Scroll" revealed memories of the Demon King’s past.

When his memories were revealed, the hero’s companions, who had thought the Demon King a stranger, discovered that Sisyphus was actually the most important person in their lives.

All along, he had been working tirelessly for this world on the brink of collapse, bearing the burden for everyone.
