YGGDRASIL, a popular DMMO-RPG that was released in 2126, has unfortunately announced its servers will be closing down after over a decade of service. Ainz Ooal Gown, a guild once feared throughout the game, containing a membership of forty-one players, was now reduced to two members active. In the final hours of the official cancellation of YGGDRASIL, the players Momonga and Herohero are left in their guild base, the Great Tomb of Nazarick.

Though Momonga wishes for his fellow comrade to stay with him until the game shut down, Herohero decides to call it a night. Now alone, Momonga is furious that his friends casually abandoned him. However, he calms down as they had a reason for quitting the game as his guild members had real life issues to deal with.

Not willing to let the last moments of YGGDRASIL go to waste, Momonga takes the Staff of Ainz Ooal Gown with him and retires to the Throne Room. As he waits for the countdown, Momonga falls asleep. Upon awakening, he finds that the shutdown has already passed and he is unable to log out. More strangely, the NPCs have gained minds and wills of their own. Understanding something is wrong, Momonga uses the loyalty of the NPCs to his advantage, and acting in a charismatic and domineering tone, as how the leader of Ainz Ooal Gown should act in regal form. Once Momonga concluded that he was no longer in the game, he wondered if he was the only player that was transported and if his friends are also on this strange new world.

Meanwhile, a unknown village is attacked by knights. The massacre is taken noticed by Momonga who initially wished to ignore it, but later decides to intervene.

Demiurge one of the Floor Guardians has misinterpreted a previous conversation with Ainz and believes he wishes for world conquest and makes it the goal of the NPCs to achieve their master’s wish.

Using his knowledge gained from Carne Village, Ainz and his battle maid Narberal Gamma register in E-Rantel to become adventurers to explore the human world. Now known as Momon and Nabe respectively, They gain the attention of a famed pharmacist named Nfirea Bareare, after he learns about a strange potion that Momon possesses.
