Overlord (2015)

In 2126, the game YGGDRASIL was released, a full-body virtual MMO with insane levels of customization for the players and their guilds. One player, Momonga, was the leader of the guild Ainz Ooal Gown, which consisted of 51 members (all playing non-humanoid races) and was one of the top guilds in its heyday. However, YGGDRASIL's servers are being shut down, and Momonga is the only one left as the clock counts down to midnight... except when it hits 12:00, Momonga doesn't leave the game -- instead he and his guild's base have been transported to a mysterious fantasy world, and all of the NPCs painstakingly crafted by his friends are now fully sentient. Momonga, trapped in the body of his Elder Lich avatar, is now the revered leader of hundreds of other non-human entities, among whom the general view of humans is as bugs to be squashed underfoot. So what else is Momonga to do but to change his name to Ainz Ooal Gown and set out to take over this new world, all in the name of finding other members of his guild who might've been transported as well... and destroy any puny humans that get in his way.
