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.
Ains and Albedo use themselves as bait as they approach the royal capital. Azuth comes to defend the capital and quickly separates the two. While the two of them exchange blows in the air, a mysterious figure comes to visit Ains.
Though Shalltear's skill set puts Momonga at a complete disadvantage, he steps forward into battle. He gave various world items to his guardians to ensure the safety of Nazarick in his absence. Now, all that is left is a battle of life and death!
The war is finally starting. The Empire plans to use this chance to see the depths of the Sorcerer King's power, whilst the Kingdom is confident that they have fully prepared themselves for this war. Gazef stands ready. Now, let the massacre begin.
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.
Ains army marches towards the royal capital to finally annihilate the Re-Estize Kingdom. Various forces prepare themselves for the coming onslaught. Before the last battle, Zanac rides alone to meet with Ains for a peaceful discussion.
Everyone in the Re-Estize Kingdom makes their final preparations as the Sorcerer Kingdom's army invades the royal capital. Some try to escape and some just wait to die. But there are a few among them who wish to fight until the very end.
Momonga reminds Shalltear that he is the master of Nazarick and that his name carries the weight of all the supreme beings of Ains Ooal Gown. After the battle comes to a close, Momonga quickly takes action to strengthen the defenses of Nazarick.
