On the night his favorite MMORPG is scheduled to be shut down, veteran player Momonga stays logged in until the clock hits zero. The screen goes dark for only a few moments before he finds himself completely immersed in the world of Yggdrasil. Left with all of his character’s devastating powers, total dominion over his NPCs, and nothing better to do…Momonga decides to take over the world.

Continuing his quest to rule this new world, Ains begins to put the pieces in place for his conquest. But between a Lizard Man tribe uprising, and performing missions as adamantite adventurer Momonga, Ains has his work cut out for him!

This land will fall to his command—the overlord is back! While Ains Ooal Gown’s conquest over Yggdrasil is bearing fruit, a deadly power struggle between empires could lead to Ains’ downfall. But that’s the least of his worries. Despite praise from his subjects, Momonga is finding it harder and harder to keep up the act as the terrifying Ains. On top of it all, Nazarick is being invaded. Can the mighty overlord maintain his reign, or will this be his final stand?

Newly crowned Ains plans his utopia, but before he can reform the rival kingdoms, he’ll have to rule them. Histerrifying nature makes allies hard to come by, but when the Dwarven Kingdom is threatened, Ains finally has achance to prove his good intentions.
