"The Freezing God" (氷結の武神 Hyōketsu no Bushin) is the fifth episode of the Overlord II adaptation. It was broadcasted on February 6, 2018.


After teleporting from the Great Lake, Victim takes his leave from his master and the rest of the Floor Guardians to return to guard Nazarick. At the newly built base in the Great Forest of Tob, Aura apologizes for its shabbiness, but Ainz Ooal Gown thinks it is satisfactory. Ainz also takes notice of a throne constructed out of bones, learning that it is a gift from Demiurge who offers it to him. Ainz hesitant to accept it and instead, orders Shalltear Bloodfallen to come forth and kneel to act as a chair for him. Although this act is supposed to serve as a punishment for her "rebellion" the vampire, however, feels ecstasy and joy while the other Guardians, save Albedo, praise Ainz's decision.

While so, Ainz decides to observe how the lizardmen reacted to his ultimatum. He uses the Mirror of Remote Viewing to observe their preparations. While shifting through the images, he comes across Zaryusu Shasha and Crusch Lulu mating. Ainz is shocked and quickly cancels the magic. Despite the rest of the Guardians are disgusted at their actions, Ainz quickly gives an explanation that the lizardmen are doing it to keep one's race alive from facing extinction.

At dawn and Cocytus awaits the lizardmen. To start the impending duel, the Nazarick Elder Guarders start clanging their weapons and feet in a rhythmic beat. Zaryusu, the chieftains, and several lizardmen warrior and their Swamp Elementals watch as Cocytus easily slashes several trees.

Cocytus greets them and before commencing the battle, he conjures two pillars of ice to create a makeshift gate. He declares those that cross the gate, will have their lives forfeit but gives the option for them to flee. All the elder lizardmen warriors and chieftains unanimously affirm their insistence to fight despite the odds and insist that the younger generation return to the village and live.

As the lizardmen charge at Cocytus, the Floor Guardian uses [Frost Aura] to encase most of the warriors in ice. The only ones left are the chieftains. Sukyu Juju and Kyuku Zuzu lead the attack. The former shooting at Cocytus with his slingshot while the latter continues the charge. Cocytus is protected by a shield, and thus, is immune to long range attacks. When Kyuku attempts to spear Cocytus, he is bisected by the God Slaying Emperor Blade.

On the other hand, Zenberu attempts to use his Martial Arts against Cocytus, but the monk's attacks are easily deflected. Further, Cocytus would then cut off one of Zenberu's arms. Zaryusu attempts to stab him with Frost Pain, but the Guardian catches the blade between his fingers. Cocytus uses his tail to swat the traveler away. The two lizardmen are saved when Shasuryu Shasha uses healing magic on them. Additionally, the Swamp Elementals tries to put up a fight against Cocytus, yet they end up being destroyed with a quick slash.

Afterwards, Sukyu tries attacking Cocytus again but to no avail. Seeing his attacks annoying, Cocytus uses [Piercing Icicles] and kills him. The next to fall is Zenberu when he tries to rush towards the Guardian, only to succeed in decapitating himself.

Cocytus seeing that Shasuryu and Zaryusu are left, parsing them for surviving for as long as they have. The two brothers exchange words of encouragement before resuming their fight with Cocytus. Cocytus respecting his opponent asks them to declare their names to him. After the introductions are done, Shasuryu uses magic to manipulate the mud to attack him, but are rebuffed by Cocytus's defenses. Later, Zaryusu uses [Icy Burst] to cloak the area in mist. The older brother attempts to strike Cocytus with his blade and is killed. Zaryusu is the last one to attack, to which Cocytus easily catches his blade once again. However, the blade begins slipping from Coctyus's grasp. Frost Pain had been coated with blood and as it slides closer to Cocytus's chest, he declares the tactic to be magnificent. Unfortunately, the blade is blocked by Cocytus's passive ability and Zaryusu is later slain.

Cocytus is praised by his master who designates him as the ruler of the Lizardmen. Cocytus asks what will be done with the slain lizardmen to which Ainz responds that they will be used to create undead. However, Cocytus states that would be a waste as the lizardmen possess a warrior's spirit that can contribute to Nazarick. Ainz surprised at Cocytus's input decides to accept it. Later, Cocytus then brings the last remaining chieftain Crusch Lulu before Ainz. Being the lizardmen's representative, Crusch declares the tribes' official surrender and allegiance to their ruler.

Ainz offers Crusch a chance to bring Zaryusu from the dead, but in return, the albino must act as Nazarick's spy amongst her people and be on the lookout for possible rebellion.

Zaryusu awakens to find Crusch hugging him and Ainz Ooal Gown commenting on his successful return from the dead. Zaryusu is weak yet in awe by the revelation that Ainz possesses such power. Zaruyus and Crusch prostate themselves before Ainz acknowledging him as a Supreme Being. Just as Ainz leaves, Zaryusu makes a request that his comrades be resurrected. Ainz considers the request and tells him to preserve the body. The episode ends with Zaryusu eventually succumbing to his ordeal and collapsing in Crusch's arms.
