Nfirea’s had breakthroughs in both potion-making and his method for wooing Enri, but sudden changes to the behavior of dangerous monsters in the region threaten to upend his happy life in this peaceful town. And when Ainz learns of these disturbances, he decides on a whim to personally investigate the source of the problem...

What do you do when your favorite game shuts down? Momonga decided to stay logged in right up until the very end. But when the servers go dark, he finds himself transported into the game world--and he's been transformed into his skeletal avatar from the game, awesome magical powers included! But what if he's the villain of his own story?

The Sacred Kingdom has enjoyed a great many years without war thanks to a colossal wall constructed after a historic tragedy. They understand best how fragile peace can be. When the terrible demon Jaldabaoth takes to the field at the head of a united army of monstrous tribes, the Sacred Kingdom's leaders know their defenses are not enough. With the very existence of the country at stake, the pious have no choice but to seek help wherever they can get it, even if it means breaking taboo and parlaying with the undead king of the Nation of Darkness!

Ainz has personally stepped in to deal with the remaining two of the Three Big Ones not yet under his control, but that doesn’t mean the danger for Carne Village has passed—on the contrary, Nazarick’s plans for Nfirea call for an all-out assault on its walls! Meanwhile, the Baharuth Empire prepares to send a covert team of workers to investigate a certain mysterious tomb that seems to have popped up out of nowhere...

The lizardman conflict comes to a decisive and bloody end as Ainz turns his attention north towards the humans once more. The Re-Estize Kingdom's princess has beauty, intelligence, and kindness in spades. She's guarded by a fiercely loyal young man-who also carries a secret torch for her. His vow to protect her will take him from courtly intrigue deep down into the underbelly of the country. Will the steadfast youth be able to protect his golden princess...?

The world is all yours. In search of lost rune technology, Ainz heads for the dwarf country with Aura and Shalltear in tow. On his arrival, instead of a welcoming party, he's greeted by an army of creatures known as the kuagoa, poised to lay waste to a dwarven city. In his quest to obtain the secrets of the runes and even the rune crafters themselves, Ainz may find himself facing not only these strange subterranean creatures, but also the most powerful race that calls the Azerlisia Mountains home-frost dragons!

Lord Ainz has made great progress moonlighting as the indomitable hero Momon, but what should be a moment of triumph is shattered--by news of rebellion. He vows to find out what has happened and to defend the honor of his guild and home--Ainz Ooal Gown.
