With the events of Re-Estize Kingdom and the Lizard Men behind them, the loyal servants of Nazarick return to their daily routines. Ains, however, is worried about the work/life balance of his NPCs. They work day in and day out without rest…

Enri meets Agu, who tells everyone that the Giant of the East and Demon Snake of the West are gathering forces to fight the master of the Monument of Ruin. Enri and the others take action, but little does she know how crazy the day will become…

Ains decides to go and see the Giant of the East and Demon Snake of the West himself. If they are similar to Hamusuke, they may have some worth as experimental subjects. They may also be useful in testing Lupisregina’s capabilities with the village.

The "Giant of the East" has come to attack Carne Village, but the villagers are willing to put their lives on the line to protect their home and families. While the goblin troop defends the front gates, Enri and Nphirea defends the village from behind.

The Tomb of Nazarick continues their plan for world domination and Ains visits the Baharuth Empire as Momon of Darkness. Meanwhile, Count Femel hires a large number of Workers to explore a certain tomb recently discovered in Re-Estize Kingdom.

The foolish workers that have entered the Tomb of Nazarick greatly anger Ains Ooal Gown. Albedo and the others have already finished preparations for their welcome and Lord Ains watches on, determined that not a single one leaves his tomb alive.

The worker group Foresight is teleported to the fighting arena in the sixth floor to challenge the great Ains Ooal Gown. Ains tries to restrain his smoldering fury as he disposes the last of the filthy thieves that dare trample into his treasured Nazarick.

Ainz sends Aura and Mare to the Empire with a message. Come and apologize or watch as your country burn to the ground. With no other option, Emperor Jircniv heads toward Nazarick with the head of a noble in tow. Though, things are not as they seem.

Re-Estize Kingdom prepares for war after receiving a declaration from the Empire that they will claim the land near E-Rantel for the Sorcerer King Gown. Gazef knows the magic caster’s strength, but he cannot stop what has already been set into motion.

Carne Village is in a pinch once again. An army led by the first prince of Re-Estize has appeared, demanding to be let in so the villagers can be questioned about Ains Ooal Gown. Enri must make a decision for the village and its people.

The war is finally starting. The Empire plans to use this chance to see the depths of the Sorcerer King’s strength and the Kingdom is confident that their have fully prepared themselves for this war. Gazef stands ready. Now, let the despair begin.

Gazef challenges Ains to a duel that is impossible to win and Ains decides to accept. The battle will soon come to an end and the fate of E-Rantel will be decided. Even amongst the bloodshed, Gazef and Ains both hold the other in deep respect.
