With season 2 just releasing its 13th episode, the official website of the Overlord anime series has announced season 3, titled Overlord III, will happen and will air a lot sooner than expected! You can expect to see Momonga and the crew back again this July.
Here is the synopsis of the series from MyAnimeList:
The final hour of the popular virtual reality game Yggdrasil has come. However, Momonga, a powerful wizard and master of the dark guild Ainz Ooal Gown, decides to spend his last few moments in the game as the servers begin to shut down. To his surprise, despite the clock having struck midnight, Momonga is still fully conscious as his character and, moreover, the non-player characters appear to have developed personalities of their own!
Confronted with this abnormal situation, Momonga commands his loyal servants to help him investigate and take control of this new world, with the hopes of figuring out what has caused this development and if there may be others in the same predicament.
Overlord‘s first season premiered in Japan in 2015 and eventually dubbed by Funimation on November 2016. With season 2 begun airing early January of 2018, season 3 is quite a fast release. Fans of the series should be eager to not have to wait too long.
