The lizardmen tribes are celebrating their victory over Iguva=41 and the undead army. The chieftains discuss Frost Pain's abilities and it's wielder Zaryusu Shasha. Zenberu Gugu decides to go wake Zaryusu, who is resting after the battle. Inside a hut Zaryusu awakens and notices Crusch on top of him. They share a brief moment until Zenberu interrupts them. He sees them and decides to leave the embarrassed couple alone.
Meanwhile, in the Great Tomb of Nazarick, Ainz holds a meeting with his Guardians. He opens the meeting by welcoming and introducing Victim, Guardian of the 8th Floor, to the rest of the other Guardians. Ainz tells Victim that he intends to use his special ability should a person attack them with a World Item. Next, he turns to Demiurge. He asks about the sheep used to make scrolls. Demiurge gives them the name "Abelion Sheep" and describes them as two legged sheep beasts. Ainz surmises that they are a subspecies of Chimera and allows him to keep doing what he's doing. After him, he turns to Shalltear, who is still depressed over her rebellion. Shalltear begs for a punishment over it which Ainz accepts and tells her that he will give her one later.
Lastly, he turns to Cocytus, who apologizes for his defeat against the lizardmen and is lambasted by Albedo. Ainz asks him why he lost. Cocytus admits that he had underestimated his foes and lacked information on them as well as the land topography. He also states that the undead army lacked commanders to give orders on the battlefield. Ainz is impressed and delighted at what he said but that he still needs to be punished for his defeat. Ainz orders Cocytus to exterminate the lizardmen alone as his punishment. However, he makes a request that the lizardmen be shown mercy which Albedo yells at him for. Ainz orders her to be silent and Cocytus states that the lizardmen are more beneficial to Nazarick alive rather than dead. He says that they are capable warriors and is against killing them for that reason. The idea is rejected at first initially, but Demiurge suggested an idea to Ainz that they can keep the lizardmen alive as an experiment to see if they can govern them without the use of fear. Ainz then accepts the idea and orders that Gargantua be activated and then he calls the meeting to a close. After the meeting with their master came to an end, Cocytus thanks Demiurge for his idea. Ainz returns to his chambers happy and realizes that someone has sprayed perfume on his bed.
Back at the lizardmen village, another undead army is spotted across the Great Lake and they notice the magical equipment that they carry. Crusch then notices that a sixth tier spell called control weather. Zenberu wonders if the "Great One" is there with them. They then watch a giant golem throw a cubed rock in the middle of the frozen lake. Then the skeletons form a staircase with their own bodies and a royal procession being formed as Ainz and his Guardians walk up to the top of the cubed rock and he sits on his throne. He sends messengers to the lizardmen asking them to send out a delegate to speak with him. Shasuryu and Zaryusu go out to meet them. They introduce themselves and Albedo orders Demiurge to make them bow down which he uses his skills to force them to bow down. Ainz then informs them that if they manage to defeat Cocytus in four hours in battle he will leave them alone. Shasuryu attempts to surrender but Ainz rejects it and leaves them after telling them that the ice will melt. He and his guardians exit by using a Gate after bidding them farewell and Demiurge releases them. After the meeting the tribal chieftains meet and decide to call their warriors to arms but Zaryusu wants only the five of them to fight which Crusch objects to but Zaryusu talks her out of it. He embraces her once more. She then asks him to impregnate her.
