## Plot

In 2126, a Full-Dive massively multiplayer online role-playing game or DMMORPG called YGGDRASIL was released, standing out among all other DMMORPGs due to its unusually high ability for the player to interact with the game. After an intense twelve-year run, the game servers are about to be shut down. Within the game exists a guild, Ainz Ooal Gown, once consisting of 41 members and credited as one of the strongest guilds in the game. Now only four of the members remain, the other 37 having quit the game, and only one, a skeletal Lich "Overlord" character named Momonga, continues to play as the guild leader, maintaining their headquarters in The Great Tomb of Nazarick. In the minutes before the shutdown he invites the remaining guild members, but of those only one appears and only for a short while before leaving. While saddened by this, he accepts the reality that his friends have their other lives to take care of and decides to stay logged in until the servers shut down.
When the shut-down time arrives, Momonga discovers that the game hasn't vanished; instead, it appears as if Nazarick has been transported to another world altogether and its various NPCs becoming actual living beings. Momonga has been trapped in the form of his game avatar, leaving him unable to use the normal player functions such as General Message, or even log out. With no other option, Momonga sets out to learn if any players like himself are in this new world. Taking on the name of the guild, Ainz Ooal Gown, as a message to any other remaining players, Momonga begins exploring the world in an attempt to figure out what has happened while searching for anyone or anything that could help him solve this mystery, while ensuring the safety of Nazarick. Ainz Ooal Gown seems to have modifications made to his behavior by in-game mechanics, because he demonstrates no moral qualms with killing and other actions that are taboo in the real world.

### Games

A mobile game Mass for the Dead was launched in late 2019 in Japan, with a global (English) version launched in early 2020. It received poor reviews, with reviewers noting it was rather simple and did not offer anything new compared to many other similar gacha games. The global version has been shut down as of March 31, 2021.
A Metroidvania game titled Overlord: Escape from Nazarick was announced on December 17, 2021, for Nintendo Switch and PC via Steam and was released on June 16, 2022.

By August 20, 2015, the nine-volume Overlord light novel series and two-volume manga series have, together, more than 1.5 million copies in circulation in Japan. By September 18, 2015, Overlord light novel and manga has over 2 million copies in circulation. By May 2016, the Overlord light novel series had 2.5 million copies in print.

In reviewing the anime adaptation, Kotaku called the Overlord anime a "magnificent power fantasy" which "brings up a very relatable theme for anyone who has played an MMORPG before."

### Overlord: The Sacred Kingdom

In November 2024, Overlord: The Sacred Kingdom earned $1.16 million in its U.S. opening weekend, ranking at #12 in the box office.
Phil Hoad of The Guardian gave the film 3/5 stars, writing, "At least in this instalment, we never see the real-world frame story outside the game, but there’s a fatalistic sense that all this is being decided elsewhere. Coupled with expansive, heroic visual character-work, the film has a classiness that, with a bit more focus, could in future put it in Princess Mononoke territory." Randy Myers of The Mercury News gave it 3/4 stars, writing, "Director Naoyuki Itô obviously relishes classic world-building elements and oversees some rather astonishing visual set pieces. All the staples are there, too: bloody battles, surprising revelations and dormant powers within unlikely sources." IGN's Mike Mamon was more critical, calling the film "more of a footnote to a long-running anime series than it is an entertaining movie experience" and adding, "The arc that inspired the movie receives only a passing mention on the TV show; The Sacred Kingdom's lackluster execution makes that short shrift feel justified." He gave the film a score of 4/10.
