Detailed Summary (Spoilers)

Momonga having found himself transported into another world in the form of his in game persona. With all the NPC's having turned into a real entities. He quickly decides to confirm if his power's and item's from game works in this new reality. After finding out that his power's are still like thiswere in game he also want's to affirm that the NPC's like in the game are still loyal to him. We are now then introduced to some of the highest ranking NPC's in Nazarick. These are the vampire Shalltear, the worm lord Cocytus, the dark elf twins Aura and Mare, the shapeshifting demon Demiurge, the dragonian butler Sebastian and the succubus Albedo. At this point he also deeply regret's one of his earlier actions which was to change the setting's of the NPC's Albedo to be in love with Momonga, thinking that he has tarnished his guild mate Tabula most precious NPC. Establishing that they are indeed still loyal, he decides that to keep their loyalty he must act as the Overlord that they see him as. To this end he set's Nazarick into motion to survive in this new and unknown world. At this time as a joke he tells Demiurge that maybe they should conquer the world.

While trying to figure out how one of his magical item's that allows him to see other place's works by accident he find's a village close by under attack by a group of knight's. Deciding to save the village to gain information on this world and at the same time test how powerful this world combatants are, he charge's forth saving a pair of sister. While using some of his magic and one of his weak summons's he find's out that the knight's are extremely weak. The village is saved and as payment he asks for information on this world which allows him to understand it much better. At this time the Knight-Captain Gazef Stronoff come's and after a brief meeting between him and Momonga it is made apparent that the attack on the village was a trap to drag Gazef out when the Sunlight Scripture surrounds the village. Gazef in a valiant attempt to exempt the villager's from the fighting is eventually overwhelmed but before he is slain Momonga uses a teleport magic to switch place with Gazef and his men. He then easily defeats and capture's the Sunlight Scripture after this he decides that with the village saved he will return to Nazarick.

Having returned to Nazarick he gather's all the high ranking NPC's to make an announcement. He then make's it clear to everyone that from this day forth his name will no longer be Momonga but will now be known as Ainz Ooal Gown. He then leave's the throne room to let Albedo tell the NPC's what else needs to be done. At this time Albedo gives the word to Demiurge who state's to all the other NPC's what Ainz had previously told him as a joke, world conquest, Demiurge wanting to fulfill any and every wish that their Overlord might hold takes this very seriously and all the NPC's in unison proclaim's that the world will be given to Ainz.

Trivia
Web Novel
 * 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.
