Chapter Summaries

After Tanjiro, Zenitsu, Inosuke, and Kanao left for Hashira training, Moyu stayed at the Butterfly Mansion to strengthen his Reverse Cursed Technique and protect Nezuko. He mastered Hollow Technique "Purple" in a remote valley, alarming Shinobu Kocho with its destructive power, then returned to the mansion safely.

• Tanjiro, Zenitsu, Inosuke, and Kanao left the Butterfly Mansion for their assigned Hashira training grounds, while Moyu stayed behind and agreed to watch over Nezuko.
• Moyu spent 50,000 Coins to acquire advanced Reverse Cursed Technique knowledge and used it to improve his healing and recover some Mental Energy.
• Over several days, Moyu trained while keeping Nezuko company at night, then went to a remote valley to test Hollow Technique "Purple."
• Moyu's first attempt to fuse Blue and Red failed and injured him, but he healed himself and analyzed what went wrong.
• On his second attempt, Moyu used a hand sign to fuse Blue and Red and fired Purple, erasing part of a distant hill and carving a long scar through the landscape.
• Shinobu Kocho rushed to the valley after hearing the blast, checked that Moyu was safe, and brought him back to the mansion, where a worried Nezuko greeted him.

Moyu continued refining his techniques and training at the Butterfly Mansion, where Sanemi Shinazugawa and Obanai Iguro challenged him to a sparring match. He defeated their coordinated attacks with ease, and the chapter ended with the group returning to the mansion after the visitors acknowledged his strength.

• Moyu trained his mental strength, Reverse Cursed Technique, Hollow Technique: Purple, and Dragon Elephant Prajna Skill, reaching its third layer.
• Mitsuri Kanroji visited the Butterfly Mansion with Sanemi Shinazugawa and Obanai Iguro, who challenged Moyu to spar.
• Moyu faced Sanemi and Obanai together, using Azure Flow Breathing and his Six Eyes to counter their attacks without using Limitless.
• Sanemi and Obanai ended the match exhausted, while Moyu praised their progress and Sanemi promised to challenge him again after another breakthrough.
• Mitsuri and the other visitors left, and Moyu returned to the Butterfly Mansion with Shinobu Kocho and Nezuko.

Moyu’s Six Eyes evolved to the Complete Stage, unleashing a vast pressure across Demon Slayer Corps headquarters before he relocated to a remote valley to control the transformation. He covered his eyes to filter the flood of information, reassured Shinobu Kocho and the Hashira that he was unharmed, and remained alone to adjust to his new perception and power.

• During meditation, Moyu’s Six Eyes began evolving, and their overwhelming pressure reached the Hashira across headquarters.
• Moyu used Blue to teleport to a remote valley, where his perception expanded and his control over Cursed Energy improved dramatically.
• Moyu covered his eyes with a black cloth to reduce the strain from the flood of information, and Shinobu Kocho found him and feared he was injured.
• Moyu demonstrated that he could move and perceive normally despite the blindfold, then explained that his eyes were fine and he had made a breakthrough.
• The Hashira gathered in the valley, accepted Shinobu Kocho’s explanation, and left Moyu to adjust; Shinobu Kocho departed after urging him to be careful.

After evolving his Six Eyes, Moyu discovered that Shinobu Kocho had been poisoning herself to kill Doma and persuaded her to abandon her plan. He removed the poison and repaired her damaged organs, leaving Shinobu free to pursue a future beyond revenge.

• Moyu returned to the Butterfly Mansion and used his Six Eyes to detect Wisteria Poison and organ damage in Shinobu Kocho.
• Moyu confronted Shinobu about her plan to use herself as poisoned bait for Doma and promised to kill him himself.
• Moyu reminded Shinobu that Kanae Kocho wanted her to live, and Shinobu agreed to let him treat her.
• Moyu used the Reverse Cursed Technique to remove Shinobu's poison and repair her damaged organs while she slept.
• Shinobu woke feeling restored, thanked Moyu, and returned to her duties with renewed energy.

Moyu detected Tamayo and Yushiro meeting with Kagaya Ubuyashiki, where Tamayo revealed four medicines intended to cure demons and help defeat Muzan. After Shinobu struggled with Tamayo's past, Moyu temporarily strengthened Kagaya and walked back with Shinobu, reassuring her that she did not have to force herself to accept Tamayo.

• Moyu sensed Tamayo and Yushiro at the Ubuyashiki residence and quietly went to investigate.
• Tamayo presented four medicines, including a treatment to turn demons human and three designed to weaken Muzan, while Moyu said he could handle Muzan himself.
• Shinobu arrived, learned Tamayo had once eaten humans, and agreed to assist with the medicines while keeping her distance from Tamayo.
• Moyu used his energy to temporarily restore some of Kagaya's vitality, though he could not remove the curse afflicting him.
• On the way back to the Butterfly Mansion, Moyu told Shinobu she did not need to force herself to accept Tamayo, easing her distress.

Tamayo’s medicine and Moyu’s life energy helped Nezuko transform enough to survive in sunlight, though she temporarily lost most of her human memories. After reuniting with Tanjiro, Zenitsu, and Inosuke, she stayed at the Butterfly Mansion while they returned to training.

• Tamayo gave Nezuko the human-restoring medicine, and Moyu used the Reverse Cursed Technique to ease her discomfort and accelerate its effects.
• Nezuko woke with childlike speech and discovered she could stand in the sunlight, though Moyu noted that her transformation was not yet complete and her human memories were missing.
• Tanjiro, Zenitsu, and Inosuke arrived, and Nezuko recognized them before reuniting with Tanjiro in tears.
• Tanjiro thanked Shinobu and Moyu, then spent the day with Nezuko as she learned words and explored the courtyard.
• Tanjiro, Zenitsu, and Inosuke stayed overnight, then said goodbye to Nezuko the next morning and returned to their training.

Nezuko spent a peaceful day at the Butterfly Mansion with Moyu, Shinobu Kocho, and Mitsuri Kanroji before Moyu was summoned to discuss the approaching battle with Muzan. Moyu rejected Kagaya Ubuyashiki’s plan to sacrifice himself as bait and persuaded the others to attack Muzan inside the Infinity Castle instead.

• Nezuko shared a quiet morning with Moyu and Shinobu Kocho, then welcomed Mitsuri Kanroji, who brought sakura mochi and a woven rabbit for her.
• A Kakushi summoned Moyu to the Ubuyashiki estate, where Kagaya Ubuyashiki told Moyu and Gyomei Himejima that he planned to use himself as bait to injure Muzan with explosives.
• Moyu warned that Nakime could send Muzan into the sunless Infinity Castle, making Kagaya Ubuyashiki’s plan to hold out until dawn unreliable.
• Moyu proposed injecting Muzan with Tamayo’s medicines and pursuing him into the Infinity Castle, where Moyu would use Hollow Purple to annihilate him.
• Kagaya Ubuyashiki accepted Moyu’s plan, and Gyomei Himejima agreed to follow it as they prepared to summon the other Hashira and assign their roles.

Moyu ambushed Muzan at the Ubuyashiki estate, injected him with four drugs, and badly wounded him with Red. After Nakime opened the Infinity Castle beneath them, Moyu entered alone while the Hashira arrived too late to follow; inside, he located Muzan and Nakime with the Six Eyes.

• Muzan confronted Kagaya Ubuyashiki at the estate and dismissed the clan’s belief that killing him would lift their curse.
• Moyu appeared behind Muzan, injected him with four drugs, and blasted him into the woods with Red.
• Moyu struck Muzan with another Red attack, erasing much of his left side as the drugs began disrupting his regeneration.
• Muzan called Nakime, whose Infinity Castle passages opened beneath Moyu and Gyomei Himejima; Moyu used Blue to pull Gyomei to safety and fell into the castle alone.
• Shinobu Kocho and the other Hashira arrived after the passage closed, and Shinobu ordered them to secure the area while Moyu fought inside.
• Moyu landed in the Infinity Castle and used the Six Eyes to locate the regenerating Muzan and Nakime.

Moyu used his spatial techniques to destroy Muzan’s Demons, then defeated Upper Rank Two Doma and Upper Rank Three Akaza, whose memories returned before he died. As Moyu advanced through the shifting Infinity Castle toward Muzan, Muzan summoned Kokushibo.

• Moyu used Cursed Technique Lapse—Blue to annihilate more than a hundred Demons, and Muzan watched the attack while ordering Akaza and Doma to kill him.
• Akaza’s Compass Needle could not detect Moyu’s fighting spirit, and his attacks failed against Moyu’s invisible defense before Moyu’s kicks repeatedly injured him.
• Doma attacked Moyu with ice-based Blood Demon Arts, but Moyu countered with Blue and Red, destroying Doma’s techniques and killing him with a maximum-output Red.
• Akaza launched his Final Form, but Moyu’s maximum-output Red erased most of his body; Akaza remembered Koyuki and Master Keizo, reclaimed the name Hakuji, and died.
• Moyu advanced toward Muzan as Nakime altered the Infinity Castle, and Muzan called for Kokushibo.

Moyu killed Kaigaku and fought Kokushibo in Infinity Castle, defeating Upper Rank One with Cursed Technique Reversal—Red. With Muzan nearly recovered, Moyu headed toward the deepest part of the castle to face him.

• Moyu erased Kaigaku with Cursed Technique Reversal—Red before Kaigaku could finish speaking.
• Moyu met Kokushibo, who asked what power he used, and agreed to explain only if Kokushibo could beat him.
• Kokushibo attacked with Moon Breathing, but Moyu countered his techniques with Limitless and Azure Flow Breathing.
• Moyu used Blue to swallow Kokushibo's Seventh Form and then overwhelmed his later attacks with Inviolability.
• Moyu's Red destroyed Kokushibo and his flesh-and-bone sword, killing Upper Rank One.
• Moyu sensed Muzan recovering from the drug and walked toward the deepest part of Infinity Castle.

Moyu battled Muzan in the Infinity Castle, using his techniques and Tamayo’s medicine to overcome the Demon King’s attacks and escape attempts. He annihilated Muzan with Hollow Technique—Purple, then blasted a route out of the collapsing castle and sped upward.

• Moyu blocked Muzan’s attacks with Limitless Inviolability, then used Blue and Azure Flow Breathing to deflect and sever his whips.
• Muzan’s broken-down medicine began aging him rapidly, while Moyu destroyed Nakime with Cursed Technique Reversal—Red and cut off Muzan’s escape through the Infinity Castle.
• Muzan failed to split apart because Tamayo’s division-inhibiting drug took effect and transformed into his Dead Infant Form.
• Moyu annihilated Muzan and a vast section of the Infinity Castle with Hollow Technique—Purple.
• As the castle collapsed, Moyu fired another Purple to open a passage and used Blue to race out through it.

Moyu returned to Demon Slayer Corps headquarters after killing Muzan Kibutsuji, ending the demon threat and lifting the Ubuyashiki curse. He helped Nezuko, Yushiro, Muichiro, and Kagaya recover, and the Corps disbanded as its members began planning peaceful lives.

• Moyu escaped the collapsing Infinity Castle, received the system's kill tally, and sensed the survivors gathered at Corps headquarters.
• Muzan's death lifted the Ubuyashiki curse and caused Tamayo to vanish; Yushiro took her Demon Transformation Medicine to become human.
• Moyu returned to the Corps and confirmed that Muzan was dead, then used Reverse Cursed Technique to strengthen Kagaya and help Nezuko and Yushiro recover.
• Moyu restored Muichiro's lost memories and further healed Kagaya as Nezuko reunited with Tanjiro and Yushiro vowed to live for Tamayo's sake.
• Kagaya disbanded the Demon Slayer Corps, and the Hashira and other survivors discussed their plans for life after the war.
• Moyu told Shinobu he might travel, and she welcomed him back to the Butterfly Mansion as everyone faced a peaceful new beginning.
