Chapter Summaries

Ren reassured Lavinia that he would not lose himself in pursuit of power, then spent the day shopping with her and the others. After Lavinia asked him to help her meet Vali, Griselda called about Xenovia and Irina Shidou—and was shocked to learn Ren had already defeated Kokabiel.

• Lavinia warned Ren to stay true to himself, and Ren told her he would not be bewitched by a Sacred Gear or sacrifice what mattered to him for strength.

• Griselda called Ren to ask him to pick up Xenovia and Irina Shidou, and Ren revealed that Kokabiel had already been defeated.
• Griselda fell silent in disbelief after hearing that Ren had taken down the powerful fallen angel executive.

Ren learned that Griselda had tasked him with looking after Xenovia and Irina Shidou, who had arrived in Kuoh Town to investigate the stolen Holy Swords.

• Jeanne told Ren that the Hero Faction planned to visit Khaos Brigade’s headquarters, and the system issued Ren a mission to confirm Ophis.

• Katerea teased Ren that she could take Jeanne’s place and love him if he proved his worth.

Ren traveled with Katerea to the Old Maou Faction’s territory in the Underworld, where he explored and activated a teleportation anchor. The chapter left him summoned by Katerea after he complained that the territory was too poor and boring.

• Ren patted Ophis’s head, gave her snacks and game consoles, and told two devils to connect electricity so he could play games with her later.
• Katerea teleported Ren from Khaos Brigade headquarters to the Underworld and gave him a scale from her true form as a pass for the Orthodox Maou Faction’s territory.

• Devil soldiers brought Ren to Katerea, who asked whether he had adjusted to the Underworld, and he replied that it was poor and had nowhere fun to go.

Ren rejected Katerea’s plan to attack the three factions and revealed its secret details, warning that her borrowed power would not make her victory possible. He began showing her a power-ranking chart, leaving Katerea confused about what the rankings meant.

• Ren decided he could help Katerea reclaim her throne by persuading her to establish a new country instead of fighting the three factions.
• Katerea raged when Ren called her army weak, but he calmly insisted her attack plan would fail.

• Ren erased the chart’s unfamiliar top tiers and pointed Katerea toward the rankings for Great Red, Ophis, and the God of the Bible.

Ren explained the gap between Katerea’s strength and the current Maous, then urged her to abandon her plan to attack the Underworld and establish a country instead. Katerea began considering whether she could use this peaceful approach to reclaim the title of Satan Leviathan.

• Ren showed Katerea his power rankings and demonstrated his speed, leaving her unable to react.
• Ren explained that Katerea was only Ultimate-class without Ophis’s power and would barely reach the Maou level with it, while Serafall and Sirzechs were much stronger.
• Katerea despaired over her years of hardship and her inferiority to the pure-blooded noble lineage.
• Ren suggested that Katerea establish a country and govern it peacefully rather than try to seize Lilith by force.
• Ren argued that Katerea could remain Leviathan wherever she was and might eventually replace Serafall if her new country succeeded.
• Katerea considered the plan and admitted that reclaiming the position of Satan Leviathan was still her goal.

Ren persuaded Katerea to abandon her alliance’s original plans and help secure her claim to Satan Leviathan’s throne, then the two grew close in her office. The chapter ended with Ren and Katerea spending the night together.

• Ren told Katerea that the Underworld would likely tolerate only one new Old Maou Faction nation and urged her to keep their plan secret from Shalba and Creuserey.
