Chapter Summaries

Meikyō and Yushiro seized control of Nakime long enough to bring the fighters out of the Infinite Castle, while Muzan reappeared and battled the Hashira. After Nakime was killed, Meikyō prepared to rejoin the fight against Muzan and transformed into Yoriichi Tsugikuni.

• Meikyō and Yushiro attacked Nakime, with Meikyō binding her and Yushiro using his Blood Demon Art to control her consciousness.
• Muzan emerged from the flesh cocoon and fought Yushiro for control of Nakime, so Meikyō used his Sharingan to suppress Muzan's consciousness.

• Meikyō and Iguro Obanai killed Nakime, preventing Muzan from returning to the Infinite Castle.
• Meikyō turned his, Kanroji Mitsuri's, and Iguro Obanai's weapons into Crimson Blades, then transformed into the man in the red haori.

Meikyō revealed himself to Muzan as Tsugikuni Yoriichi and fought him while the Hashira joined the battle. Muzan was pressured by Meikyō’s clones and the Hashira’s Crimson Blades, but the fight continued amid the explosions from his attacks.

• Muzan confronted the Hashira after the deaths of his Twelve Kizuki and identified Rengoku Kyojuro and Himejima Gyomei as Kokushibo’s killers.

• Meikyō and Muzan tried to stall for time, but Meikyō attacked when Muzan could not escape by splitting into fragments.
• Meikyō used Sun Breathing and created more than ten clones, while Muzan realized he could fight Yoriichi and laughed that he had grown weaker.
• Rengoku Kyojuro rallied the Hashira, who used Crimson Blades and the Transparent World to help Meikyō damage Muzan.
• Muzan unleashed invisible shockwaves from the mouths on his arms, and the Hashira with the Transparent World helped the others evade them.

Meikyō and the Hashira fought to keep Muzan Kibutsuji occupied until dawn, while Meikyō’s abilities grew under the pressure. Muzan tried to escape, but the Demon Slayer Corps surrounded him again, and the battle continued with fifteen minutes left until sunrise.

• Meikyō fought Muzan Kibutsuji with the Hashira’s support, combining his abilities and sensing that he was close to a breakthrough.
• As dawn approached, Muzan noticed that his opponents had recovered and decided to flee, unaware that his hair had turned white and his strength was declining.
• Muzan blasted Meikyō into a wall, but Meikyō healed himself with the Mystical Palm Technique while the Hashira and Demon Slayer Corps surrounded Muzan.

• Rengoku Kyojuro and Shinazugawa Sanemi saved the injured Tomioka Giyuu as the remaining Hashira continued fighting Muzan with fifteen minutes until dawn.

• With four minutes until sunrise, Muzan Kibutsuji launched another shockwave and tried to flee, but Uchiha Meikyō returned and severed his head with the Sun Halo Dragon Dance.
• Muzan Kibutsuji transformed into a massive monster, while Meikyō used New Sun Breathing and the Transparent World to attack the wounds Tsugikuni Yoriichi had left in him.
• As dawn broke, Meikyō relentlessly slashed Muzan Kibutsuji, preventing him from growing a body that could shield him from sunlight.
• Rengoku Kyojuro joined Meikyō and used Sun Breathing to help damage Muzan Kibutsuji until he turned to ash in the sunlight.
• Meikyō collapsed after the battle, and Kochō Shinobu confirmed that he was only exhausted; as the Demon Slayer Corps relaxed, Meikyō began to enter a new place in his dream.

Uchiha Meikyō met Tsugikuni Yoriichi in a vision and learned that Yoriichi was an incarnation of the world's consciousness, created to help the Demon Slayer Corps fight Muzan. Yoriichi thanked Meikyō for helping defeat Muzan and free his elder brother from his obsession.

• Tsugikuni Yoriichi welcomed Meikyō into a cabin and gave him glowing golden tea as a gift.
• Yoriichi revealed that the cabin could appear anywhere and showed Meikyō his sleeping body at the Butterfly Mansion, where the three little girls cared for him and Kochō Shinobu tended to Uzui Tengen.
• Yoriichi explained that Muzan and demons were like cancer cells in the world, while the Demon Slayer Corps were its white blood cells.
• Yoriichi told Meikyō that the world's consciousness had created him to teach Breathing Techniques and leave clues that would eventually lead to Muzan's defeat.
• Yoriichi thanked Meikyō as both an outside force who helped the world defeat Muzan and someone who helped Tsugikuni Yoriichi's elder brother find release.

Tsugikuni Yoriichi explained that the World Power in Meikyō’s tea would gradually evolve his eyes and repair some bloodline defects, while warning him against overusing the power before his body matured. Yoriichi gave Meikyō his swordsmanship and Breathing Techniques experience, then disappeared; Meikyō woke to find energy steadily flowing into his eyes as they began evolving.

• Tsugikuni Yoriichi told Meikyō that the tea contained World Power that would help his eyes evolve over several months and restore some of their power after depletion.
• Yoriichi warned Meikyō that using the evolving eye power too much while he was young could burden his body and cause terminal illnesses.
• Meikyō asked whether genes from related clans could further repair his bloodline, but Yoriichi said the world had little World Power left to spare.
• Yoriichi granted Meikyō good fortune while he remained in the world and passed on his human swordsmanship and Breathing Techniques experience.
• Yoriichi vanished, and Meikyō fell unconscious before waking in an unfamiliar room with life-filled energy steadily flowing into his eyes.

Meikyō woke after five days unconscious and was greeted by Kanzaki Aoi and the Demon Slayer Corps, then ate a feast while recovering. Ubuyashiki Kagaya invited him to a celebration banquet for Muzan’s defeat, which was ready and waiting for Meikyō.

• Kanzaki Aoi entered Meikyō’s room and found him awake and getting dressed, then rushed off to tell everyone the good news.
• Meikyō joined the gathered Demon Slayer Corps members for a large meal and learned they had brought food because they cared about him.

• Meikyō explained that he had been unconscious for five days and suspected his evolved Sharingan had increased his need for energy.
• Ubuyashiki Kagaya arrived with Oyakata Amane and invited Meikyō to the celebration banquet prepared to mark Muzan’s defeat.

After Muzan's defeat, Meikyō urged the Demon Slayer Corps to remain active and work to prevent future wars, then left to travel the world in search of ways to achieve peace. He returned to Konoha and considered his strength, his growing Mangekyo, and how Demon Slayer Blade compared with Ama-no-Ohabari.

• At a celebration, the Hashira and others discussed their plans after Muzan's defeat, while Giyuu mistakenly believed everyone liked him.
• Meikyō warned that human wars could kill tens of millions and asked the Demon Slayer Corps to stay together and work to prevent them.

Meikyō reviewed the gains he brought back from the Demon Slayer World and began incorporating Tsugikuni Yoriichi’s swordsmanship teachings. After seeing Meikyō’s skill, Uchiha Yu urged him to take on high-level missions and eventually inherit his influence within the clan.

• Meikyō considered the Demon Slayer Blade, three Upper Rank Demons’ blood samples, and Tsugikuni Yoriichi’s gifts, including a bloodline-evolving tea and knowledge of Breathing Techniques and swordsmanship.
• At the Uchiha Clan Compound training ground, Uchiha Yu watched Meikyō practice and told Shisui that his swordsmanship was beyond what even a Three-Tomoe Sharingan could follow.
• Shisui brought Meikyō water after his practice, and Meikyō said he had no immediate plans.
• Uchiha Yu advised Meikyō to take on more high-level missions, earn enough merit to become a Jonin, and prepare to inherit Yu’s influence within the clan.

Meikyō advised Uchiha Yu against rushing Shisui through the Ninja Academy, warning that a Shinobi World War might soon begin. He continued training and taking missions while waiting for his Mangekyō Sharingan to awaken, leaving plans to seek another world for later.

• Meikyō remembered that he was still a Special Jonin, and Uchiha Yu urged him to become a Jonin as Shisui's mentor.
• Uchiha Yu planned to teach Shisui the Ninja Academy curriculum in a year and have him graduate early, hoping he would grow into a powerful ninja.
• Meikyō argued that Shisui needed time to make friends and develop, and warned Uchiha Yu that another Shinobi World War might be near.
• Meikyō told Uchiha Yu and Shisui to keep his warning secret, prompting Uchiha Yu to reconsider Shisui's training plan.

• Meikyō revealed that his Mangekyō Sharingan had awakened the previous day and estimated his strength at about three stories tall.

Shimura Danzō maneuvered to send Uchiha Meikyō on a dangerous mission to Amegakure, and Hiruzen Sarutobi approved the assignment while planning his own countermoves. Meanwhile, Meikyō tested his newly awakened Mangekyō Sharingan abilities in the Forest of Death.
