Without enough information, the Cardinals decide to spy on Jircniv. Meanwhile, Jircniv is unable to handle the stress of dealing with Ainz and losing the war has caused his hair to begin falling out. Jircniv hopes the Slane Theocracy will be his secret allies against Ainz, so he hires the Adamantite adventurers Silver Thread Bird as guards while meeting their representatives. At a gladiatorial display in the coliseum, Jircniv meets the representatives but in the coliseum the Empire’s strongest gladiator, the Warrior King, is suddenly challenged by Ainz. Jircniv panics as he believes Ainz somehow manipulated the entire meeting to force Jircniv to either support Ainz, or publicly betray him and ask the Theocracy for an alliance.

| Following Albedo’s departure to Re-Estize, Ainz decided upon a publicity stunt to show his power and mercy. Along with Ainzach, Ainz smuggled himself into Jircniv’s Empire. Ainzach pointed out hiring experienced adventurers could be problematic, so it would benefit Ainz to train amateurs. Ainz decided a fight in the coliseum would advertise to potential trainees so Ainzach set up a meeting with a fight promoter. Ainz met with Fluder to gather information and rewarded his loyalty with a book detailing the exact nature of souls. Meeting Osk the fight promotor Ainz takes an interest in a runecrafted sword from the Dwarven Kingdom. Osk arranged for Ainz to fight the Warrior King. Now, in the present, Ainz meets the Warrior King, a troll named Go-Gin who is quite intelligent. Deciding he likes Go-Gin, Ainz offers to hire him should Go-Gin lose their fight and he agrees. For the sake of fairness Ainz uses no high tier magic and equips Clementine’s triple daggers. Go-Gin is thrilled to have faced someone of Ainz’ strength and swears to one day reach his level. Ainz kills Go-Gin and announces to the audience his desire to train adventurers to explore the entire world and that they need not fear death in his service as he resurrects Go-Gin before their eyes.

Ainz hopes the experience will broaden Shalltear’s mind. In private, Ainz reveals the runes are from the Yggdrasil game and wonders if it was another player who taught them to the dwarves. Aura suggests to Shalltear that she should try to understand Ainz actions. They arrive at Feo-Raidho city, but find it abandoned except for Gondo Firebeard, a dwarf miner. Ainz explains his interest in an alliance and in runes. Gondo admits not many runesmiths remain since it is easier to use enchantments, and Dwarven society has been in decline for years. Ainz offers his support in helping the dwarves recover their pride, so Gondo swears loyalty. They encounter Quagoa, a race of mole people who eat metal to make their fur impenetrable. Ainz orders Shalltear to capture them alive and is pleased when she correctly deduces his reason for doing so. Ainz learns the Quagoa are a support force for an army led by Clan Lord Pe Riyuro who, at this very moment, is leading an army to destroy what is left of the Dwarven Kingdom. |||||||

Ainz offers the Dwarves Regency Council a Trade Alliance as well as Ainz’ guarantee of protection. Ainz also offers to reclaim the Dwarven Royal capital of Feo Berkana from the Quagoa, despite the Quagoa’s numbers and a Frost Dragon living nearby, in exchange for all runesmiths relocating to his kingdom. Despite their reservations the Council agrees. Ainz meets the runesmiths and informs them he wants them to totally revive their craft and they gladly accept. Gondo is touched that rune crafting, an art practised by his family for generations, will be saved from decline. He also offers to act as guide to the Royal Capital, in exchange for Ainz’ complicity in stealing a valuable book on runes from the treasury. Ainz instructs Shalltear on strategic thinking in case they meet whoever killed the two Death Knights. Ainz also looks forward to meeting a real dragon in person. |||||||

Shalltear shares what she learned from the experience and Ainz is proud of her. Ainz summons Demiurge to report on progress with the Roble Holy Kingdom.

Hilma is surprised when Ainz blames himself instead of her and becomes devoted to him, describing his mercy to the other Eight Fingers. Albedo explains to the Floor Guardians that Phillip was supposed to incite the commoners into rebelling against the nobility; Ainz would then peacefully absorb Re-Estize into the Sorcerous Kingdom, but Phillip provoked war instead. Ainz agrees an example is required but privately is not happy his plan failed. Ainz sends a letter to the Re-Estize king, warning that the Sorcerous Kingdom, Baharuth Empire, Dwarven Kingdom, Dragon Kingdom, Roble Holy Kingdom, and a powerful figure called the Faceless all hold the Re-Estize Kingdom responsible for the attack on the transport and may declare war.

Brain, who now holds Gazef’s sword Razor Edge, decides to evacuate his sword students out of Re-Estize. Demiurge moves soldiers to surround Re-Estize, preventing other countries interfering. Ainz worries victory will be too easy; since more can be learned by experiencing failure, the Floor Guardians won’t actually learn anything if they win without trying. At Pestonya’s request Ainz visits the Frozen Prison on Nazarick’s fifth floor to see Nigredo, Albedo’s older sister. Nigredo and Pestonya wish for Ainz to stop massacring humans as they believe humans have infinite potential that Ainz is wasting. Ainz agrees but points out the need to set an example of what happens to kingdoms who oppose him. He decides to massacre the coastal city of E-Naeul but leave some humans alive. Count Naeul hires the Four Armaments, mithril level adventurers, to protect E-Naeul. One of them, Lilynette, agrees to marry Naeul’s twelve year old son in exchange for Naeul’s family heirloom, the Five-Colour Holy Sword.

Ainz admits he is using Re-Estize as an example to other kingdoms. Zanac demands to know Ainz ultimate goal, and in a moment of genuine honesty, Ainz admits he is seeking happiness. Ainz also learns Gazef’s sword is with Brain at Re-Estize castle. Zanac wonders if he was ever actually fit to be a king. Returning to his army, a group of nobles are so terrified they betray him. The traitors beg Ainz for mercy and present him Zanac’s severed head. Ainz demands to know where Zanac’s armour is, as it also belonged to Gazef, then hands the traitors to Neuronist at the Frozen Prison, promising them they will receive mercy, that mercy being death once they have begged Neuronist to kill them to escape her expert torture.

Backed into a corner, Ainz takes the unusual decision to kneel and beg for mercy, claiming he is the victim and Re-Estize the criminals. Aganeia agrees but claims Ainz went too far so he has to die. Albedo breaks into the barrier to defend him, causing Aganeia to retreat and regroup with Azuth. Aganeia is revealed to be Tsaindorcus Vaision, the Platinum Dragon Lord. He is curious that Albedo broke the barrier while Ainz could not, meaning either Albedo possesses a World Item or she is actually stronger than Ainz. He theorizes Albedo might actually be a "Player" and Ainz an NPC, and begins making plans to destroy them both. He also considers whether to kill Azuth in order to give his YGGDRASIL armour to someone stronger. Ainz and Albedo return to Nazarick, where it is revealed "Ainz" was actually Pandora’s Actor and the real Ainz was observing the battle from Nazarick. He demands Pandora’s Actor tell him everything he learned about Riku Aganeia. |||||||

Brain in particular refuses as he hopes to duel Ainz, but he gives Gazef’s sword to Renner and Climb to return to Ramposa. Cocytus and Aura arrive and begin destroying the city. Brain, while searching for Ainz, encounters Cocytus who agrees to duel him after a brief introduction. Despite his training and increased abilities, Brain is killed instantly. Cocytus is impressed at Brain’s skill and warrior spirit.

Renner asks Climb to become a demon like her so that she wouldn't be alone, which he accepts. Meanwhile, Albedo visits Phillip, who expects thanks for providing her a casus belli. Instead, Albedo tortures him to death, revealing that Phillip's father requested that she punish him for his actions. In the aftermath of the war, Ainz meets Marquis Raeven and puts him in charge of the Kingdom's former territory. The Sorcerer King also asks the marquis if this conflict made the world understand the foolishness of opposing him, to which he affirms that it did, leaving the Overlord satisfied with this outcome. |||||||
