Momonga has a son named (Y/N) IRL. He took care of him ever since his GF died while in child birth. When his son was 10 Momonga showed him a DMMO-RPG game called Yggdrasil and let him into his and his friends clan of Ainz Ooal Gown. (Y/N) made his character using a feature called gene combiner so his ingame character is the son of Momonga and Albedo. 8 years later and thousands of in-game hours and thousands of dungeon raids later the servers of Yggdrasil are closing. Momonga and his son have decided to spend the last hours of the game online and wait for the servers to shut down. After all both the father and son have fond memories of their time in Yggdrasil. I do not own the anime series or the manga. All of those rights go to their owners.

In this version, There was no Momonga, in this world, Susuki Satoru, was born a "SHE", making the history of Ainz Ooal Gown, more different and more impactful in the world of YGGDRASIL. Follow the demon Empress, in a new world, where she would have to act the way a supreme being has to, even thought she had not idea of what the hell is going on and make things as she goes along.

I traveled to the world of Overlord, only to discover that the game Yggdrasil was on the brink of shutdown. What was I supposed to do if my application to join Ainz Ooal Gown failed? Kael didn't panic. Instead, he spent three years within Yggdrasil, repeatedly synthesizing several World Items-specifically, Thermal Stones-and petitioned the game operators to create a unique plugin item. This item allowed Kael to form contracts with selected players, granting them rare professions or even changing their race once certain conditions were met. And then, Kael successfully descended into the New World. Now, how much of an impact will his arrival have on the destiny of this world? Will the nations of humanity continue down the path of their doomed fate? How will the True Dragon King, the strongest warrior in the world, respond? And most importantly... Can the Great Tomb of Nazarick still be defeated?
