The final hour of the popular virtual reality game Yggdrasil has arrived. Yet, Momonga, a formidable sorcerer and leader of the shadow guild Ainz Ooal Gown, chooses to linger in the game as its servers start shutting down. To his astonishment, even though midnight has fallen, Momonga remains fully aware in the body of his avatar, and furthermore, the non-player characters seem to have gained distinct personalities! Facing this strange circumstance, Momonga orders his devoted followers to aid him in probing and mastering this new realm within the fractured digital landscape, hoping to uncover the cause of this anomaly and whether others share his plight in the echoing void of virtual existence, seeking for resolution.
