Chapter Summaries

Seiya offered the Baharuth Empire the support of his demi-human army to help form an alliance against the Sorcerer Kingdom, in exchange for the Empire becoming a vassal of the Kingdom. Guelkyniv accepted the terms if the allied forces successfully repelled the Sorcerer Kingdom.

• Seiya revealed that the Holy Grace Demi-human Kingdom had nearly a million people and could field around three hundred thousand soldiers, then asked for a seat at Guelkyniv’s Council of Nations.
• Seiya said he would help oppose the Sorcerer Kingdom only if the Empire paid a heavy price, and Guelkyniv recognized that Seiya’s support could bring the Holy Kingdom and Theocracy into the alliance.

• Guelkyniv agreed to Seiya’s terms on the condition that the allied nations successfully repel the Sorcerer Kingdom, despite Bajude’s objections.
• Guelkyniv told Bajude that accepting the Kingdom’s rule was the only way to save the Empire, while Seiya silently let him believe the terms reflected a grand strategy.

The Baharuth Empire welcomed delegations from the Holy Kingdom and Slane Theocracy as it organized a coalition against the Sorcerer Kingdom. Guelkyniv met the Theocracy’s powerful angel, Otto, who dismissed the meeting and complained that Shalltear Bloodfallen’s pursuit of him had driven him to attend.

• The Baharuth Empire called the Sorcerer Kingdom a nation of monsters and urged humanity to unite against Ainz Ooal Gown, prompting the Holy Grace Demi-human Kingdom, the Holy Kingdom, and the Slane Theocracy to join the war.
• Citizens in Owentall watched the Holy Kingdom delegation arrive and praised the Holy Princess, its knights, and its angels.

• Guelkyniv welcomed Nigun and praised Otto’s strength after recognizing him as a formidable being comparable to Ainz Ooal Gown.
• Otto demanded that the meeting begin and said Shalltear Bloodfallen’s insistence on having children with him had made him come to the Empire.

At a meeting in the Empire, Otto reacted with unexpected deference when he learned that Seiya was the delayed representative, while Guelkyniv and the others waited to greet him. Seiya arrived with the Elite Ten of the Demi-humans, whose humanlike appearance and formidable auras made Guelkyniv reconsider the strength of their army.

• Infinite Magic belittled Seiya and the Demi-humans, but Otto ordered her to be silent when Guelkyniv identified Seiya as the arriving representative.

• Guelkyniv struggled to introduce the ten tribal chieftains after sensing that their strength matched or exceeded the Black Scripture.

Seiya won the support of the Demi-human Nation and led the nations in forming a massive alliance against the Sorcerer Kingdom. The chapter ended with Seiya named commander-in-chief and the Theocracy’s Black Scripture captain sidelined.

• The Black Scripture captain warned Seiya to keep his distance from demi-humans, prompting the Elite Ten to angrily defend their loyalty to him.
• Seiya said he would take responsibility for the demi-humans, and the Elite Ten knelt and declared their devotion to him.

After the Council of Nations, Guelkyniv proposed marrying Lana to strengthen his ties to the Kingdom and Seiya, while Seiya worried Lana would reject him. In the Kingdom, Zanac welcomed Albedo, whose arrival prompted nobles to court the Sorcerer Kingdom’s powerful representative.

• Nigun explained that the Theocracy avoided seeking command of the allied forces because Ainz Ooal Gown could assassinate its commander.
• Guelkyniv asked Seiya to arrange his marriage to Lana, hoping the alliance would help him regain the Empire’s independence if the Kingdom and Seiya fell out.
• Seiya cautioned Guelkyniv that Lana might not suit him and that the match should depend on her wishes, but Guelkyniv insisted he had accepted marriage as a political duty.
• Zanac held a banquet in Tier to welcome Albedo, and the Kingdom’s nobles eagerly sought her favor because of her beauty and influence in the Sorcerer Kingdom.

Albedo questioned Zanac about Seiya’s absence from the banquet and learned that he had been exiled, then sought answers from Princess Lana. Lana challenged Albedo over her failures to help Seiya become king or control him, leaving their alliance strained.

• At Zanac’s banquet, Albedo asked why Seiya had not attended, and Zanac said he had exiled his younger brother for opposing the alliance with the Sorcerer Kingdom.

• Lana told Albedo that Seiya had subdued the Demi-humans, founded their nation, and joined an Allied Nations Army of 1.3 million soldiers.

• Ainz took Albedo to the treasury and brought out equipment and magical items belonging to his former companions.

• Shalltear Bloodfallen identified several powerful figures among the opposing forces, including the Kingdom’s Third Prince, and mocked the Black Scripture for being outmatched.

• Seiya’s blue pillar of magic pierced the meteor and broke it into fragments, then continued toward the Sorcerer Kingdom’s undead army.

After the Battle of the Kazi Plains, Seiya became famous across the continent, and nations sought to join the Alliance of Nations to protect themselves from the Sorcerer Kingdom.

• Guelkyniv decided that the Golden Princess’s wishes and Seiya’s opinion mattered most, since Seiya and his transformed demi-humans had been the only forces able to confront the Sorcerer Kingdom.
