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?

Three paths converge when the warrior Unglaus and the rookie fighter Climb witness a scuffle involving an old gentleman who turns out to be none other than Sebas himself. While the first of the group searches for his reason to fight, the second aims to become stronger for the sake of his life savior, and the third resolves to carve a safe path for the girl he has chosen to protect. What will become of this unlikely trio?

Ainz, the undead overlord, is in dire need of better information about the world he's found himself in, and to get it, he travels to the city of E-Rantel. Disguised as a mere adventurer, he accepts a mission to venture deep into an eerie forest, but the swirling shadow of intrigue hides the road ahead...

The day of the battle with the Great One fast approaches. Can Zaryusu unite the lizardmen tribes before they're all wiped from this earth? The Red Eyes have agreed to an alliance, but the Dragon Tusks will be trickier. They prize strength above all else-meaning Zaryusu will need to defeat their chief in combat before they'll even think of hearing him out!

With Momon spearheading the charge, the Royal Army finally enters into a pitched battle with Jaldabaoth and his horde of demons-who will come out on top? And, more importantly, what is the true objective of Demiurge’s “Gehenna” plan...?!

It's come down to this--a fight to the death, mano a mano, Ainz versus Shalltear! With the odds stacked against him, Ainz faces off against the deadly vampire lord. But Shalltear is not the only threat facing our hero--ahem, our overlord! In a far-distant reptilian kingdom, nefarious forces are on the move. Will Ainz need to meddle in the affairs of mortals yet again...?

Bloodlust is in the air--and plenty of real blood too! Shalltear is on the hunt, but she may not like what she finds. Ainz sent her out for information, but when Blood Frenzy activates, the time for talk is over. Can anyone, undead or alive, put an end to her reign of terror...?

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...?

Posing as an adventurer in order to gather information about the world he's found himself in, Ainz ventures forth into the city, posing as an adventurer in order to gather information about the world he's found himself in. Finding work was easy enough, but when it leads to a plot that will devastate the city, he''s forced to take action--and will his powers be enough against the terrifying warrior Clementine?

After undergoing an intense interrogation, Sebas is faced with a difficult decision—maintain his loyalty to his master or stay by Tsuare’s side. Thankfully, a rare glimmer of Ainz’s benevolence grants Sebas the privilege of doing both! But with this boon comes even greater hardship. Sebas may have been allowed to keep Tsuare, but can he keep her safe…?

The dust has settled after the final battle with the Elder Lich, but it's only the calm before the storm. When the overlord returns bearing the full weight of his army, the Lizardmen know this is truly the end. For the denizens of Nazarick, though, the outcome is more uncertain. Cocytus has grown to respect the brave tribal warriors--it would be such a shame to kill them all...

At last, Demiurge’s schemes in the kingdom begin bearing fruit…Between Jaldaboath and a powerful fighter capable of manipulating insects, the beleaguered humans have no choice but to rely on the Blue Roses!
