Detailed Summary (Spoilers)

Ainz together with Narberal Gamma heads to E-Rantel changing their names to Momon and Nabel while they take on their adventurer identities. Having to start out as the lowest ranking adventurer's they head to an inn in order to rest up, while there they get into a small fight and Ainz gives away one of his Yggdrasil potions as a compensation to a female adventurer. The next day they team up with the adventurer group called the Swords of Darkness to go on a monster hunt. Before leaving they are interrupted by Nfirea Bareare who want's to hire Momon as an escort to Carne Village. His reason for doing this being the fact that the potion Ainz previously handed out has made Nfirea very interested in him. Ainz accepts his request if the Swords of Darkness group can come along which Nfirea accepts.

While traveling to Carne Village a sinister group named Zuranon lead by Khajiit Dale Badantel and assisted by Clementine is working to raise an undead army in the hopes of turning E-Rantel into the second undead city. To realize their scheme they need to get a hold of Nfirea so that he can use a very powerful magic item, because of his innate talent that allows him to use any magic items. With him having left the city no other choice but to wait for his return.

On their way to Carne Village they get into a fight of goblins and ogres which Ainz uses as a way to show off his powers and raise his fame. Eventually making their way to Carne Village they all discover and surprise that the village has gone through quite the overhaul. They have started to make defensive barricades to better defend themselves. Also using the magic item that Ainz previously gave to the sisters while saving them they have summoned a large group of veteran goblins that have been helping them with guarding the village and teaching the villagers how to defend themselves. It also turns out that one of the sisters, Enri Emmot, is a close friend of Nfirea. The next day they head into the forest to gather medicine herb for potion making. Ainz wanting to increase his fame provokes the Virtuous King of the Forest into attacking them with the help of Aura. To Ainz disappointment the Virtuous King turns out to be a giant hamster, still he decides that it might still has some use and makes it submit to him and makes it his pet. Everyone is impressed by the majestic form of the Virtuous King while Ainz can only see a cute hamster it is also given a new name, Hamsuke.

Upon their return to E-Rantel the group splits up with Momon and Nabel heading to the adventurer guild to register Hamsuke as their beast. While doing this Zuranon attacks, killing the Sword of Darkness group and kidnapping Nfirea. On his way to Nfirea's house he meet's up with Lizzie Bareare, Nfirea's grandmother, upon discovering that Nfirea has been kidnapped he is hired by Lizzie to rescue him. They then set out to the cemetery where Zuranon has released their undead army to attack the city. Fighting their way through a hoard of undead they eventually reach Zuranon's hiding place. Upon defeating Zuranon and rescuing Nfirea, Ainz and Narbarel is given a huge boost in fame and rapidly advance to a Mythril rank adventurer.
