The six attempted to clear the final level of the labyrinth but ultimately failed, and the world came to an end.

However – when Desir thought he would meet his demise, what is revealed before him is the world… thirteen years ago?!

Desir is returned to the past, back to the time when he enrolled at the nation’s finest magic academy – Havrion. He is reunited with his precious friends, and is prepared to change the past to save the world and his loved ones…!

Three years remaining before the emergence of the Shadow World!

In the world of Kyushu, players full of resentment gathered together, dripped blood as an alliance, and vowed to make the big devil go away.

Except for Lubei.

He is the so-called devil.

“Say I’m the devil, blame me for pitting you, I’m an NPC, how could I pit you, that’s how immortals are!”

Vainqueur Knightsbane is your average dragon: a giant, fire-breathing lizard who loves to take naps on his golden hoard, kidnap princesses for fun, and make the life of adventurers miserable. Vainqueur's only pleasure in life is to watch his treasure get bigger, one coin at a time.

So when a would-be thief turned unwilling minion tells him about "classes," "levels," and "quests," Vainqueur wonders if maybe, just maybe, he should consider a career change.

After all, why bother hunting monsters for free when you can get paid for it?

“When everyone worked hard just to obtain pills, artifacts, wealth, or power. Well, hehe. All I need to do is buy them through the Invincible Exchange System!” Our protagonist said with a smirk on his face.
