- Description from Novelupdates

After announcing it will be discontinuing all service, the internet game ‘Yggdrasil’ shut down… That was the plan, but for some reason, the player character did not log out some time after the server was closed. NPCs start to become sentient. A normal youth who loves gaming in the real world seemed to have been transported into an alternate world along with his guild, becoming the strongest mage with the appearance of a skeleton, Momonga. He leads his guild ‘Ainz Ooal Gown’ towards an unprecedented legendary fantasy adventure!

Life, at times, can be quite unpredictable. But who could have thought it would be to this extent? It's unlikely that any sane person would imagine that in a single day, fate would grant them the chance to witness the end of one world and the opportunity to save another. But is that what our main character truly wants? That is an entirely different question...___________Gain early access to new chapters and support my work on Patreon:patreon.com/nitwishIt's a tale of my attempts to go off the rails of canon and write something distinctly different from it, though I only managed to diverge more or less by the 21st chapter. Some arcs will be reworked, some will remain unchanged, and some will be completely rewritten or cut out. However, the overall plot is unlikely to change. In places, I will alter things for my own convenience. Also, the world's “system” will be severely trimmed down, as I'm not a fan of systems and all those numbers. Something like that.

“I got transmigrated into a novel because of a bad review?”

Eren found his life turned upside down when he woke up as the character that he had just finished cursing in a negative review!

Not only had he been reborn as an antagonist that he hated, but he was an Elder at a Devilish Sect?

It would've been fine if that was the only problem, but that was just the beginning as he remembered that the Character was a spy sent into the Devil Sect by the Mythical Hero Academy... A character that died within the first fifty chapters?!
