The story begins with the last day of Yggdrasil, a popular online game which is being quietly shut down. Our protagonist Momonga decides to stay in his beloved game until the last moment, so waits for the forced logout. Unexpectedly, the server does not shut down and Momonga is stuck in a skeleton avatar in another world. “The powerful Overlord” needs now to discover the new world and face the continuous challenges that arise.

The novel Chronicles of the Hero of Frosimar is a story about the failures of the protagonist not the successes.“It’s not good.”The First Emperor, who conquered the whole world, closed his eyes with a brief appreciation (after reading the novel).But the moment he opened his eyes again, there were only a few lines about him in the Chronicles of the Hero of Frosimar.This was because he became an imprisoned prince who met death with his first appearance (in the novel).
