Ch. 521Let This Land Be Put to the Sword! / Offer Everything to the Supreme One
Saigō ordered Nazarick to begin a war to unify the world, while reassuring Momonga that he could neutralize the world's dangerous powers. After Saigō and Albedo were together in the bathhouse, Albedo encountered Shalltear outside the suite, who mocked her apparent injuries.
- Saigō reviewed Demiurge's report and announced that Nazarick would wage war to save and rule the world, with Momonga as its ruler and Saigō as its god.
- Demiurge eagerly left to plan Nazarick's invasion, while Momonga privately thanked Saigō for returning and discussed how he had worked to preserve his humanity.
- Momonga warned that unknown forces might threaten Nazarick and explained his research into the Eight Desires Kings; Saigō promised to neutralize the world's World Items.
- Momonga agreed to take Sebastian and pursue the unification plan by a different approach, and Saigō affirmed his intent to bring goodwill through war.
- Saigō left the Great Tomb after bathing with Albedo, who staggered from his suite and met Shalltear, who taunted her about her condition.
