Overlord

As the popular virtual reality game Yggdrasil approaches its final moments, Momonga, a formidable wizard and leader of the dark guild Ainz Ooal Gown, opts to remain logged in during the server shutdown. Surprisingly, even after the game was supposed to end, Momonga finds himself fully alert in the avatar of his character. More astonishingly, the non-player characters have begun exhibiting their own personalities.

Faced with this unexpected reality, Momonga orders his faithful followers to assist him in dominating and exploring this new world. His goal is to uncover the reasons behind these mysterious changes and determine whether anyone else shares his situation.
