Overlord

Momonga is a regular salaryman who leads a guild in an DMMO-RPG known as Yggdrasil. After twelve years of playing the game, the servers are finally shutting down. Momonga logs in for the last time, seeing the game to its end. However, after the clock strikes midnight, nothing changes.

Momonga continues his efforts to protect Nazarick from the unknown forces he may be up against in this world. As he manipulates the Mirror of Remote Viewing, he notices a village being attacked and decides to test his strength against humans.

Momonga sets out with Narberal disguised as humans under the names of Momon and Nabe for the city of E-Rantel. There they register to become adventurers in order to gain more information about this unknown world. As they do, evil gathers around them.

Momonga and his group continue to Carne Village. There they see that the villagers are working toward fortifying their defenses against possible future enemies. Nphirea meets up with Enri and asks her about this man named Ains Ooal Gown.

Momonga and Narberal begin their respective battles against Clementine and Khajit. Momonga takes this chance to learn about the mechanics of fighting in this world, but in the end, he must show Clementine the consequences of offending him.

Momonga does damage control at the guild while he assesses the reason for Shalltear’s revolt. Coming to the conclusion that she is under an incurable status effect, Momonga goes to the treasury to retrieve some of the powerful weapons of Nazarick.

Momonga reminds Shalltear that he is the master of Nazarick and that his name carries the weight of all the supreme beings of Ains Ooal Gown. After the battle comes to a close, Momonga quickly takes action to strengthen the defenses of Nazarick.

Cocytus gives a declaration of war to all the tribes of the Lizardmen, expecting an easy takeover. However, the Lizardmen decide to try to unite their tribes against their common foe.

The alliance of the Lizard men win the battle and defeat the army of undead. The defeat guardian Cocytus and the new ability to learn from their mistakes, prove that the guardians can adapt to new situations. Ainz Ooal Gown therefore changes his tactics, ordering Cocytus to bring the Lizard men to their knees and under the rule of the Great Tomb of Nazarick.

With the events of Re-Estize Kingdom and the Lizard Men behind them, the loyal servants of Nazarick return to their daily routines. Ains, however, is worried about the work/life balance of his NPCs. They work day in and day out without rest…

Enri meets Agu, who tells everyone that the Giant of the East and Demon Snake of the West are gathering forces to fight the master of the Monument of Ruin. Enri and the others take action, but little does she know how crazy the day will become…

The "Giant of the East" has come to attack Carne Village, but the villagers are willing to put their lives on the line to protect their home and families. While the goblin troop defends the front gates, Enri and Nphirea defends the village from behind.

The foolish workers that have entered the Tomb of Nazarick greatly anger Ains Ooal Gown. Albedo and the others have already finished preparations for their welcome and Lord Ains watches on, determined that not a single one leaves his tomb alive.

Ainz sends Aura and Mare to the Empire with a message. Come and apologize or watch as your country burn to the ground. With no other option, Emperor Jircniv heads toward Nazarick with the head of a noble in tow. Though, things are not as they seem.

Carne Village is in a pinch once again. An army led by the first prince of Re-Estize has appeared, demanding to be let in so the villagers can be questioned about Ains Ooal Gown. Enri must make a decision for the village and its people.

Gazef challenges Ains to a duel that is impossible to win and Ains decides to accept. The battle will soon come to an end and the fate of E-Rantel will be decided. Even amongst the bloodshed, Gazef and Ains both hold the other in deep respect.

Albedo personally makes her way to Re-Estize Kingdom as an envoy of the Sorcerer Kingdom. Meanwhile, the people of Re-Estize continue to do what they can to recover from the recent war and prepare for the future. Though not everyone has peace in mind.

While Albedo and the others make their moves toward world domination, Ains has his own little plan. He wants to cultivate true adventurers to explore the unknown, like the players in Yggdrasil. His recruitment efforts bring him to the Baharuth Empire...

Ains decides to lend a hand to the dwarves fighting against the Quagoa, but not for free. He wants to gather Gondo and the other runesmiths for the Sorcerer Kingdom. At the same time, Ains happens to find the perfect chance to teach Shalltear a thing or two.
