Chapter Summaries

After the Demon Country Federation secured a phased victory in the Great Underground Labyrinth, Rimuru considered how the Empire’s greater forces still threatened the war. She dismissed King of Wisdom’s suspicions about Ari and resolved to deepen her bond with him by getting him into bed.

• Rimuru assessed the Empire’s remaining forces and concluded that the fighting in the Labyrinth was only a minor skirmish before the Empire’s strongest forces joined the war.
• After the Empire’s invading army was nearly annihilated, Rimuru gathered everyone for a debriefing and used King of Wisdom Raphael to confirm that the Labyrinth was secure.
• Rimuru reasoned that Chloe’s warning about her death could fit other timelines in which she had not awakened and lacked the allies protecting her now.
• King of Wisdom raised suspicions about Azhdaha and Morax, but Rimuru cut off the analysis and insisted that she trusted Ari.
• Rimuru decided to prepare for the future by deepening her bond with Ari, considering using an aphrodisiac or Sleeping Red Tea to get him into bed.

Rimuru sent nearly all the Demon Country Federation’s forces to eliminate the remaining Imperial Army, then approved Kouyou’s request to join Benimaru on the battlefield. Benimaru’s protests failed, leaving him flustered as Kouyou took his concern for her safety as a sign of affection.

• Rimuru resolved to find a way to get Ari onto her bed, while Mo Li sensed that someone was watching him and dismissed the uneasy feeling.
• Rimuru ordered the Demon Country Federation’s cadres to wipe out the remaining Imperial forces without anyone dying, and Benimaru volunteered to lead the attack.
• Diablo accepted a decapitation mission, and Mo Li sent Carrera into battle while Rimuru stayed in the Great Underground Labyrinth under his protection.
• Kouyou entered the control room and asked Rimuru to let her fight alongside her fiancé, Benimaru.
• Benimaru objected, but Rimuru approved Kouyou’s request and the others supported her; when Benimaru worried about her safety, Kouyou blushed, and he realized his words had made matters worse.

Benimaru objected to Kouyou joining him on the battlefield, but Shuna and Mo Li overruled him. Mo Li assigned Kouyou as Benimaru’s adjutant and pressed him to choose between Kouyou and Alvis after the war, leaving the two women eager to win his hand.

• Benimaru protested when Rimuru discussed Kouyou accompanying him to the battlefield, and Shuna scolded him for his indecision and Kouyou’s efforts to win his favor.
• Kouyou declared that she would prove herself, while Alvis confronted her and the room’s onlookers began betting on which woman Benimaru would choose.
• Mo Li silenced the gathering and ordered Kouyou to accompany Benimaru as his adjutant, which Benimaru and Kouyou accepted.
• Mo Li told Benimaru to make his choice after the war and promised to bless his wedding, delighting Kouyou and Alvis while leaving Benimaru conflicted.

Rimuru launched the attack on the Eastern Empire and sent Souei to rescue the missing Toreni, while Mo Li stayed behind with her in the Great Underground Labyrinth. Rimuru suspected an enemy might exploit their isolation, but King of Wisdom found no threats and Mo Li assured her she was safe beside him.

• Mo Li promised to bless Benimaru's wedding, stirring envy among the monsters and prompting Rimuru to fantasize about winning his affection.
• Rimuru dispatched the Demon Country Cadres through teleportation magic to attack the Eastern Empire.
• Souei reported that Toreni had been missing for nearly ten days and was likely being held by an unknown enemy, so Rimuru sent him to reinforce her.
• After the others departed, Rimuru and Mo Li remained alone in the conference room while Mo Li considered how to increase his power.
• Rimuru worried that a mysterious enemy might exploit their isolation, but King of Wisdom reported that the labyrinth contained no threatening entities.
• Mo Li reassured Rimuru that nobody could harm her while he was beside her, leaving her frozen in disbelief.

Rimuru learned that the Labyrinth held no threat to her, while Mo Li’s changes had already prevented the assassination plot from the Eastern Empire. Masayuki Honjo now traveled as an ordinary adventurer, and Rimuru and Mo Li arrived at the control room to find Veldora, Azhdaha, and Ramiris gathered there.

• King of Wisdom confirmed that no suspicious individuals or threats remained in the Labyrinth, and Mo Li reassured Rimuru that she was safe.
• Mo Li reflected that the Eastern Empire’s original assassination plan had been prevented because Masayuki Honjo never became Rimuru’s trusted collaborator and the Imperial knights could not approach her.
• Diablo’s seal had weakened Masayuki Honjo’s Heroic Tyranny, allowing him to travel as an ordinary adventurer while training in the Labyrinth with Baning and Ji Wu.
• Baning and Ji Wu stayed with Masayuki in the Demon Country Federation under orders to protect him, while Mo Li watched them and kept them from causing trouble.
• Rimuru and Mo Li went to the control room, where they found Veldora, Azhdaha, and Ramiris; Rimuru then noticed familiar figures behind Veldora.

Veldora and Azhdaha complained to Rimuru and Mo Li about being left out of the fighting, but Mo Li deterred them from challenging his sisters or himself. Toreni then reported that Kagurazaka Yuuki had sent Mixed Legion members into the Jura Great Forest to free Laplace, Forthman, and Tear, and that Souei had captured them after Toreni discovered their approach to Guyun Pavilion.

• Veldora complained to Rimuru that he and Azhdaha had not been allowed to fight, and Azhdaha agreed that he wanted a real opponent.
• Mo Li offered to take Veldora to fight his second sister, frightening Veldora into silence, then offered to spar with Azhdaha, who also backed down.
• Veldora urged Toreni to tell Rimuru and Mo Li what had happened, and the exhausted Toreni stepped forward as Souei guarded captured humans.
• Toreni explained that the captives belonged to Kagurazaka Yuuki's Mixed Legion, which had infiltrated the Jura Great Forest to rescue Laplace, Forthman, and Tear from beneath Guyun Pavilion.
• Kagurazaka Yuuki had equipped his subordinates with a container holding part of his Ability Erasure power to try to breach Mo Li's barrier, but Toreni discovered them as they approached Guyun Pavilion.

Toreni and Souei captured members of the Mixed Legion sent by Kagurazaka Yuuki, prompting the Demon Country Federation to recall its grudge against the Middle Clown Chain. When Veldora mocked Azhdaha over his old near-possession by the clowns, Azhdaha turned on him, and Rimuru sent them to settle the quarrel in the labyrinth arena.

• Toreni and her sisters fought the Mixed Legion in the Jura Great Forest for ten days before Souei arrived and helped capture them.
• Souei and the others identified the captured soldiers as members of the legion commanded by Kagurazaka Yuuki, who had sent them to free the clowns imprisoned beneath Guyun Pavilion.
• The group recalled how Laplace, Forthman, and Tia had nearly controlled Azhdaha before Morax suppressed them and Mo Li helped stop Azhdaha's rampage.
• Veldora mocked Azhdaha about the incident, and Azhdaha grew furious while Veldora retreated behind Rimuru and continued provoking him.
• Rimuru dragged Veldora in front of Azhdaha and told them to fight in the labyrinth arena, then hid behind Mo Li as Azhdaha demanded to know whether Veldora was joking.

Rimuru questioned three imperial prisoners, but their intelligence proved useless, so she had Souei take them away and had King of Wisdom analyze a device containing Kagurazaka Yuuki’s Ability Erasure. Meanwhile, Azhdaha beat Veldora for mocking his embarrassing past, and the chapter ended with Veldora returning battered and complaining.

• Azhdaha dragged Veldora out of the control room and beat him for bringing up Azhdaha’s humiliating past.
• Mo Li showed no interest in the prisoners or their connection to the incident involving Laplace and the others.
• Souei explained that he had brought the imperial prisoners to Rimuru because they claimed to have important intelligence.
• Rimuru learned that the prisoners knew only information the Federation already had, apart from a device containing Kagurazaka Yuuki’s Ability Erasure, which she gave King of Wisdom to analyze.
• Rimuru sent the prisoners away with Souei, then Azhdaha returned with a battered Veldora trailing behind him.

Rimuru watched Ruotuo beat Veldora while the assembled forces prepared for battle, and Misha returned to Karigulio with news that the Empire’s invading army had been annihilated. As Misha urged him to retreat, Karigulio clung to the hope that the elites sent into the Great Underground Labyrinth would return with useful intelligence.

• Ruotuo beat Veldora, leaving him battered and sulking in a corner while Rimuru and the others returned their attention to the battlefield.
• Benimaru, Kouyou, The Original Yellow, Alvis, and the other leaders finished assembling their forces on the surface.
• Karigulio anxiously awaited news from the hundred elites he had sent into the Great Underground Labyrinth two days earlier.
• Misha returned to the Imperial command headquarters and told Karigulio that the Magic-infused Tank Legion, the airships, and the rest of the main force had been wiped out.
• Misha urged Karigulio and his staff to retreat, but Karigulio insisted on waiting for Krishna, Major General Miniz, and the other labyrinth-bound elites to bring back intelligence.

After Krishna revealed that the Empire's elite force had been destroyed inside the Great Underground Labyrinth, Karigulio ordered a retreat. Agra appeared at the command post to stop them, and his murderous reaction to a question about Rimuru and Morax left the confrontation poised to escalate.

• Krishna returned from the labyrinth as its sole survivor and reported that Ze'Chion and the other labyrinth monsters had killed the Imperial elites, including Reha and Bazan.
• Krishna described the labyrinth's powerful guardians, prompting Karigulio and his officers to blame the Intelligence Bureau and fear that the Empire had been misled.
• Karigulio agreed to withdraw the remaining forces toward the Empire after his commanders, Misha, and Krishna urged him to retreat.
• Agra entered the command post and announced that the lords had ordered every Imperial soldier killed or captured.
• A vice commander asked whether Agra's lords were Rimuru and Morax, and Agra responded with a ferocious expression and murderous aura.

Agra demanded that Karigulio and the Empire’s surviving soldiers surrender to the Demon Country Federation as slaves, demonstrating his overwhelming strength by killing an adjutant who insulted Rimuru and Morax. Karigulio rejected enslavement and proposed reparations and an alliance instead, leaving Agra’s response unresolved.

• An adjutant questioned Agra about the envoys and named Rimuru and Morax, so Agra killed him with a swift sword strike.
• Agra ordered Karigulio and the surviving soldiers to disarm and surrender as slaves within half an hour.
• As Agra prepared to leave, Karigulio called him back and refused the terms of surrender.
• Karigulio proposed that the Empire pay reparations and form an alliance with the Demon Country Federation, arguing that together they could rule the continent.

Karigulio rejected Agra’s surrender demand and resolved to lead the remaining Imperial soldiers into a hopeless battle, while arranging for Misha to escape and report to the Emperor. As the Federation’s forces assembled, Kloot watched Carrera, the Original Yellow, appear above the Yellow Legion.

• Karigulio offered Agra cooperation, but Agra dismissed his proposal and demanded that the Imperials submit or die.
• Karigulio chose to fight rather than surrender, and asked Misha to escape and report his failure to Emperor Rudra.
• Karigulio’s adjutants, strategists, and the wounded Krishna pledged to fight alongside him, while Misha departed with four Immortal-level Imperial Knights.
• Karigulio ordered the remaining Imperials to begin their preparations immediately, and the Federation’s armies gathered for an attack.
• Kloot praised the Imperials’ resolve as Carrera appeared above the Yellow Legion.

Carrera prepared to unleash Nuke Magic as a warm-up before the battle, but Agra stopped her by reminding her that the armies had agreed to a half-hour truce and that Lord Morax would disapprove. When the Imperial Army suddenly charged before the deadline, Carrera turned her anger on the breach, leaving Agra fearing for his life.

• Kloot welcomed Carrera and her group into the Yellow Legion's vanguard and told them they could fight without coordinating with or protecting his forces.
• Carrera began gathering Nuke Magic to test which spell would make the grandest entrance, alarming her adjutant Agra.
• Agra reminded Carrera that their half-hour agreement with the enemy barred either side from attacking, and Carrera stopped when he warned that Lord Morax would be unhappy.
• The Imperial Army charged before the agreed deadline, enraging Carrera and making Agra fear that she would kill him.

Carrera’s Gravity Collapse devastated the Imperial Army, and Kouyou and Benimaru’s spells destroyed the remaining troops, ending the battle in under three minutes. Karigulio tried to arrange a surrender so Misha could escape with the Empire’s intelligence, but Diablo appeared and offered to become their opponent.

• Agra admitted his mistake and urged Carrera to attack, while Esprine helped redirect her anger toward the Imperial Army.
• Carrera unleashed Gravity Collapse, crushing and obliterating most of the charging Imperial soldiers.
• Kouyou’s Demonic Sky Red Flower Flame and Benimaru’s Black Flame Purgatory wiped out the remaining troops, leaving the Imperial Army with no chance to escape.
• Karigulio collapsed into despair and ordered his officers to negotiate surrender so Misha and the others could escape safely.
• Diablo appeared inside the command post and dismissed surrender, telling the Imperial officers to face him instead.

Diablo confronted Karigulio and the Imperial command, crushing their hope by revealing that their escape party and supporting soldiers were already dead. He left Karigulio alive in utter despair, intending to make him suffer rather than granting him an easy death.

• Diablo appeared in the command post and introduced himself as Rimuru’s loyal servant, while Karigulio tried to stall him so Misha could escape.
• Diablo revealed the corpses of the four guards sent to escort Misha, shattering Karigulio’s hopes and prompting Krishna and the others to attack him.
• Diablo snapped his fingers and destroyed the command post, showing that the more than one thousand soldiers outside had also been killed and their souls taken.
• Diablo killed the remaining adjutants and strategists with another snap, leaving Karigulio alive among the bodies.
• Karigulio collapsed into despair as Diablo admired the scene and resolved to torment him rather than kill him quickly.

Diablo let Karigulio awaken as a Human Saint, hoping to test his own strength against a powerful opponent. Despite Karigulio's Mythical Grade armor and newfound confidence, Diablo easily killed him and harvested his soul.

• Diablo allowed Karigulio to break through to the Human Saint realm, and Karigulio regretted the soldiers’ deaths caused by his earlier foolishness.
• Karigulio donned the Mythical Grade armor bestowed by Emperor Rudra and believed his new power would let him defeat Diablo.
• Diablo eyed Karigulio’s armor as a valuable prize and dismissed Karigulio’s claim that he would destroy him.
• Karigulio attacked Diablo with a full-powered punch, but Diablo effortlessly neutralized it and called him weak.
• Diablo grew tired of Karigulio’s attacks, killed him, and harvested his soul.

Diablo defeated Karigulio, collected the Imperial soldiers’ corpses, and left to report to Rimuru. Watching the battle footage, Rimuru learned Carrera’s Gravity Collapse spell through King of Wisdom, while King of Wisdom remained wary of the unfathomable Morax.

• Diablo effortlessly killed Karigulio, harvested his soul, and considered the Empire’s Royal Guard Knights potential opponents to help him grow stronger.
• Diablo collected the fallen Imperial soldiers’ corpses for Rimuru or as possible demon-summoning sacrifices, then set off to report back.
• Rimuru watched footage of Carrera destroying the remaining Imperial troops with Gravity Collapse and admired Benimaru’s improved control of Black Flame.
• King of Wisdom analyzed Gravity Collapse and taught the spell to Rimuru, who decided to rely on its cheats to grow stronger.
• King of Wisdom reflected that it could not analyze Morax and resolved to prepare contingencies despite Rimuru’s attachment to him.

Rimuru prepared to revive the Imperial soldiers killed in the Great Underground Labyrinth, but Mo Li shattered King of Wisdom’s concealed space and appeared before she could begin. After explaining that he had come because Rimuru’s hidden location worried him, Mo Li approved the revival plan, and Rimuru and King of Wisdom prepared to start it.

• Rimuru began preparing to revive the Imperial soldiers, whose souls King of Wisdom had reserved for Rimuru’s subordinates.
• Mo Li detected Rimuru’s disappearance, used his precautionary connection to locate her, and shattered the concealed space to reach her.
• Rimuru welcomed Mo Li, while Diablo resented his sudden arrival and King of Wisdom wondered how he had found them.
• Mo Li explained why he had come, and Rimuru and King of Wisdom realized his precaution had revealed her location.
• Rimuru blamed King of Wisdom for proposing the revival plan as she explained it to Mo Li, who approved it.
• Rimuru and King of Wisdom prepared to begin the revival project.

King of Wisdom Raphael revived the Imperial soldiers with Pseudo-Souls, then questioned Mo Li about his identity and intentions. Mo Li said he was Morax of the Demon Country Federation and wanted to protect the people he cherished.

• After Rimuru agreed to the plan, King of Wisdom took control and began calculating how to revive the Imperial dead.
• King of Wisdom created Pseudo-Souls and used the Ultimate Soul Revival Technique to restore nearly hundreds of thousands of Imperials, though they remained unconscious while adapting.
• King of Wisdom approached Mo Li and identified herself as Raphael while asking what he was and why he was approaching her.
• Mo Li told King of Wisdom that he remained Morax of the Demon Country Federation and wanted to protect everything he cared about, including someone indispensable to his life.

Mo Li reassured King of Wisdom that his feelings for Rimuru and his promise to protect her were genuine, and Rimuru returned to herself after their conversation. Karigulio then awakened in a strange dark space and found Rimuru and Mo Li waiting for the others.

• Mo Li told King of Wisdom that Rimuru was indispensable to him and promised, in the name of the Contract, to protect what he cared about.
• King of Wisdom warned Mo Li that she would be watching him, then relinquished control of Rimuru’s body.
• Rimuru embraced Mo Li and grew embarrassed when she mistakenly thought he had learned about her plan to use sleeping medicine on him.
• King of Wisdom comforted Rimuru as she blamed her for the awkward misunderstanding.
• Karigulio awakened in a dark space, realized he had died, and saw Rimuru and Mo Li waiting nearby.
• Rimuru chose to wait for the others to awaken before explaining the situation to them all.
