VRMMO Rustyria.

Players become heroes, summoning and commanding legendary heroes who fell 500 years ago battling the Demon King.

Together with them, defeat the Demon King and save the world! A full-fledged fantasy adventure!!

...is the selling point of the VRMMO world into which I've been reincarnated.

What's more, I've been reborn into the dying world of 500 years ago. As the younger self of the hidden boss from the era when the heroes fought the Demon King.

Although I've been reincarnated as the hidden boss, possessing the strongest labyrinth and skills, the Demon King can only be harmed by a hero's attacks.

In the game's lore, both the Demon King and the hidden boss ultimately end up sealed, their conflict unresolved.

"If this is the case, I have no choice but to use the combined power of the hidden boss and their labyrinth to defeat the Demon King and prevent the world's collapse!"

The Demon King cannot be defeated by conventional means.

Then I'll simply have to outsmart them all! I'll deceive both good and evil, even the world itself, to defeat the Demon King and reverse the world's destruction!

Act cunningly, corrupt the heroes and make them your subordinates, and expand your labyrinth while absorbing demonic power to defeat the Demon King!

Thus, the dark hero's grand deception, involving the entire world, now begins.
