Before long, the Non-Player Characters begin coming to life and exhibiting personalities of their own as well, and Momonga's entire guild is seemingly transported to a new world. However, instead of being logged out at the scheduled time, Momonga finds himself stuck in the body of his in-game avatar, a skeletal lich who serves as the Evil Overlord of a tomb of monsters. One of the game's dedicated guildmasters, a salaryman known as 'Momonga', decides to remain logged in until the servers are shut down. Its story begins on the last day of a once popular virtual reality Massively Multiplayer Online Role-Playing Game called YGGDRASIL.

It has been adapted into a light novel published by Enterbrain and illustrated by So-bin, a monthly manga by Miyama Fugin, and a Summer 2015 anime series produced by Madhouse.
