This is the original version of the Overlord series written by Maruyama Kugane (丸山くがね) under the same name. It is divided into two parts and is still being updated periodically.
The story begins with YGGDRASIL, a popular online game which is quietly shutting down on its last day. Our protagonist Momonga decided to stay until the last moment in his beloved game and wait for the force log out. Unexpectedly, the server did not shut down and Momonga is stuck in his skeleton body and transferred to an unknown world. "The Powerful Overlord" now needs to face the New World and continuous challenges.

Web Novel and Light Novel Differences: Plot
Overlord Volume 1
- Attack on Carne Village is not related with the Sunlight Scripture.
- Gazef spars with a Death Knight by Ainz's request. As Death Knights are specialized in defense and not good at attack, the fight ends in a draw. (Ainz withdraws the Death Knight and tells Gazef that he's the winner)
- As a result, Ainz does not have a chance to confirm the world's power balance, and the Slane Theocracy does not notice the existence of Nazarick for now.
Overlord Volume 2
- Instead of Ainz, Narberal Gamma becomes the Adventurer "Momon" alone, using illusion magic.
- Brita, whose name is Baniara in the Web Novel, uses the same room with Momon. Since she does not like the smell from the herbs used to cure wounds, she gives a Minor Healing Potion to her.
- While the Swords of Darkness did not exist in the Web Novel, Momon confronts the Axe of Cyclone instead.
- "Momon" first works as a porter of the Axe of Cyclone. So they didn't die and go their separate ways without an incident.
- Lizzie Bareare tries to learn how to make red potion from Momon directly, but is refused.
- Momon defeats Khajiit Dale Badantel by chance during his promotion test.
- Momon introduces himself as an apprentice of Ainz Ooal Gown.
Overlord Volume 3
- Shalltear succeeds in catching Brain Unglaus, making him one of her servant vampires.
- Thus, Shalltear does not encounter the Black Scripture and become mind-controlled.
- This makes the whole story in Volume 3 quite short. The chapter "True Vampire", which is the base story of volume 3, is contained between Momon's first request with the Axe of Cyclone and defeating Khajiit Dale Badantel.
- Momon introduces Shalltear as 'Camila', one of the three apprentice of Evileye.
- Treasury was described in a side story.
Overlord Volume 4
- Main story remains quite the same. Just some 'daily life' parts of Nazarick are added in the Light Novel version.
Overlord Volume 5
- Main story remains quite the same. Blue Roses is described with more details in the Light Novel version, related with Momon.
- Sebas Tian and Climb part ways after training. Climb returns earlier, he tells Renner and Lakyus about Sebas and the brothel. He was sent to rescue slaves.
Overlord Volume 6
- Only Demiurge comes to the capital, having a short battle with Blue Roses before returning.
- Demon invasion does not occur. Sebas Tian destroys the Eight Fingers on his own.
- Sebas saves not only Tuare, but also other women captured by the Eight Fingers.
- Renner assumes Sebas and Demiurge are connected with someone, possibly their master.
