Chapter Summaries

With one hour until sunrise, the battered Demon Slayer Corps fought Muzan in a desperate war of attrition, but his devastating shock wave knocked back the Hashira and gave him time to prepare to escape. As Muzan began to writhe, Uesugi Sasuke stirred beneath Giyu Tomioka’s protection.

• The Kasugai Crow announced that sunrise was one hour away, and Zenitsu Agatsuma, Sanemi Shinazugawa, and Gyomei Himejima rallied to keep fighting Muzan.
• The surviving Hashira repeatedly attacked Muzan’s vital cores with their Bright Red Nichirin Swords while he unleashed sweeping strikes across the battlefield.
• Muzan released a ring-shaped shock wave that hurled Sanemi Shinazugawa, Gyomei Himejima, and the other nearby swordsmen into the ruins.
• Muzan began preparing to split apart and escape as Uesugi Sasuke’s eyelids and index finger twitched under Giyu Tomioka’s protection.

Sasuke drifted through darkness and exhaustion after his battle with Kokushibo, but memories of the people he had protected and a vision of Itachi gave him the will to continue. He awoke in Giyu Tomioka’s arms, his weakened Rinnegan shining as he prepared to face Muzan Kibutsuji.

• Sasuke longed to sleep forever as memories of his battles and the people he had protected surfaced in the darkness.
• Tanjiro, Kyojuro Rengoku, Shinobu Kocho, Tengen Uzui, and others appeared in his memories and renewed his resolve.
• Itachi appeared, told Sasuke he was no longer alone, and urged him to finish the final battle before vanishing as crows.
• Sasuke opened his eyes in Giyu Tomioka’s arms, and his weakened Rinnegan illuminated the battlefield and the fighters’ conditions.

Though severely injured and unable to move, Sasuke used Amenotejikara to save Mitsuri Kanroji and Obanai Iguro, then repositioned Gyomei Himejima for a devastating strike against Muzan Kibutsuji. After the second use nearly exhausted him, Sasuke still believed he controlled the battlefield.

• Sasuke awakened in Giyu Tomioka's arms, too depleted and injured to move.
• Sasuke used Amenotejikara to swap Mitsuri Kanroji and Obanai Iguro with a boulder, saving them from Muzan Kibutsuji's shock wave.
• Sasuke swapped Gyomei Himejima with a falling bone-whip fragment, placing him above Muzan with the fragment's downward momentum.
• Gyomei struck Muzan with Stone Breathing, Fifth Form: Wheel Guard, crushing one of Muzan's brain cores.
• Sasuke coughed up blood and his vision faltered after using Amenotejikara twice, but he remained confident he could direct the battle.

Obanai Iguro and Mitsuri Kanroji confessed their love and promised to marry in another life before using Sasuke’s remaining chakra to make one final attack on Muzan. They severed the tentacles supporting his body, but Muzan’s bone spikes pierced them as they fell together.

• Sasuke’s power let Gyomei Himejima crush one of Muzan’s brains, briefly stunning the Demon King.
• Mitsuri Kanroji and Obanai Iguro, saved from death by Sasuke, reunited amid the rubble and confessed their love to each other.
• Obanai Iguro asked Mitsuri Kanroji to marry him in another life, and she accepted.

• Obanai Iguro and Mitsuri Kanroji used their Breathing forms to sever the tentacles supporting Muzan’s body, opening a massive gap.
• Muzan’s bone spikes pierced Obanai Iguro and Mitsuri Kanroji, and they fell from the sky holding each other.

Tanjiro linked all twelve Sun Breathing forms into the thirteenth and attacked Muzan, while the surviving Corps members protected him. Muzan recognized Tanjiro as the vessel he coveted, pierced him with bone whips, and lifted the dying boy as Sasuke found himself unable to use his eye power.

• Tanjiro drew on his father’s kagura and Yoriichi’s legacy to link the twelve Sun Breathing forms into the thirteenth.
• Tanjiro attacked Muzan’s cores with his burning Bright Red Nichirin Sword as the surviving Corps members cleared away Muzan’s tentacles and bone whips.
• Muzan became determined to take Tanjiro’s body and focused his attacks on him, abandoning his defenses against Himejima and Shinazugawa.
• Muzan’s bone whips and claws pierced Tanjiro and lifted him into the air, making him drop his sword.
• Sasuke tried to activate Amenotejikara from Giyu’s arms but could not feel any power in his left eye.

Kyojuro Rengoku rescued Tanjiro from Muzan and stood alone against the Demon King to protect the surviving Demon Slayers. As Kyojuro unleashed his final strength, Sasuke watched with a faint smile.

• Muzan prepared to inject his blood into the captured Tanjiro while the injured Demon Slayers could not intervene.
• Kyojuro used Flame Breathing, Ninth Form: Purgatory, to burn through Muzan's bone whips and catch Tanjiro.
• Kyojuro set Tanjiro down and faced Muzan, declaring that the senior Demon Slayers would protect those who came after them.
• Kyojuro used his own esoteric Flame Breathing to shield the others from Muzan's barrage of blades.
• Sasuke watched Kyojuro from Giyu Tomioka's arms as Kyojuro vowed to stop Muzan and charged into the fight.

As the Demon Slayer Corps tried to hold Muzan until sunrise, Muzan compressed himself and split into billions of tiny particles to escape. Just as the blood cloud seemed impossible to stop, Giyu felt the body in his arms stir with a faint, godlike will.

• Kyojuro Rengoku used his burning sword to shield Tanjiro and the others while Sanemi Shinazugawa urged him to let them help.
• The Kasugai Crow announced that sunrise was thirty minutes away, and Muzan decided to abandon the fight and survive.
• Muzan contracted into a dense flesh core, then split apart in a shock wave that scattered the Demon Slayers and formed a rapidly spreading blood cloud.
• Sanemi Shinazugawa despaired as the particles threatened to escape, but Giyu Tomioka felt the still body in his arms awaken with a faint will.

Sasuke used Chibaku Tensei to forcibly gather Muzan Kibutsuji’s scattered cells into a massive sphere of flesh, trapping him. After the technique cost Sasuke his Rinnegan and left him near death, he urged his companions to destroy the prison before he lost consciousness.

• Sasuke, badly depleted and bloodied, rose in Giyu Tomioka’s arms and refused to let Muzan escape.
• Sasuke applied Chibaku Tensei’s gravity directly to Muzan Kibutsuji’s scattered cells, forcing them to converge.
• Muzan’s flesh and blood compressed into a writhing sphere more than fifty meters wide, trapping the Demon King.
• Sasuke lost the light in his Rinnegan, spat blood, and shouted for his companions to blow the prison apart.

As Sasuke’s Chibaku Tensei prison began to fail, Tanjiro understood that Sun Breathing’s Thirteenth Form was the unbroken repetition of its twelve forms. He awakened a brilliant crimson blade and launched an all-out attack on Muzan, calling on everyone to lend him their strength.

• Sasuke used his final strength to warn the survivors that the prison was close to breaking.
• Tanjiro, exhausted and barely able to hold his sword, recalled his father performing the Kagura Dance and Yoriichi demonstrating Sun Breathing.
• Tanjiro realized the Thirteenth Form was a continuous cycle linking all twelve forms into an unending attack.
• Tanjiro’s Demon Slayer Mark blazed as he repeated the Sun Breathing forms and turned his blade crimson.
• Tanjiro shouted for everyone’s strength and unleashed a desperate slash at Muzan’s collapsing prison.

Tanjiro and the surviving Demon Slayer Corps members combined their strength in a final strike that destroyed Sasuke’s flesh cage and left Muzan in his infant form. Muzan crawled toward a patch of shadow, but dawn sunlight struck his hand before he could reach it.

• Tanjiro called on the survivors to lend him their strength, and Rengoku, Gyomei, Sanemi, Giyu, Zenitsu, and Kanao joined their attacks with his Sun Breathing.
• Sasuke saw the fighters’ energies merge through Tanjiro and form a beam that pierced the flesh cage and blasted a crater into the earth.
• The survivors discovered Muzan had transformed into a gigantic infant, sacrificing his offensive abilities to survive until he could reach the shadows.
• Muzan crawled toward a nearby building’s shadow while Sasuke recognized his desperate attempt to escape the sunlight.
• Dawn broke, and sunlight struck Muzan’s hand just before he reached the shadow, burning him as his agonized shriek rang across the battlefield.

Muzan Kibutsuji was erased by the rising sun, ending the thousand-year battle, but the survivors paid a terrible price. As Tanjiro Kamado collapsed, a hidden piece of Muzan’s flesh infected him, and he became a new Demon King immune to sunlight.

• Muzan Kibutsuji disintegrated completely in the sunlight as Uesugi Sasuke watched the thousand-year curse end.
• The exhausted survivors faced the battle’s cost: Obanai Iguro, Mitsuri Kanroji, and Gyomei Himejima had died, while others lay wounded or unconscious.
• Giyu Tomioka dragged the unconscious Uesugi Sasuke to safety, then collapsed beside him.
• Tanjiro Kamado fell after the battle, but a surviving piece of Muzan’s flesh shot into his back wound.
• Tanjiro revived with one demonic eye, endured the sunlight unharmed, and became a new Demon King.

After Tanjiro Kamado delivered the decisive blow against Muzan, he rose again as a demon who could withstand sunlight. The exhausted Demon Slayer Corps realized that Muzan’s dream had come true in the worst possible way.

• The surviving slayers saw that Muzan had vanished and believed the battle was over.
• Tanjiro Kamado lay motionless with a fatal wound as Nezuko rushed to him.
• Tanjiro’s body revived, healed, and transformed into a demon.
• Tanjiro endured the sunlight and unleashed an aura more powerful than Muzan’s.
• Giyu Tomioka recognized that Muzan’s dream had come true.

Demon King Tanjiro attacked Zenitsu and Inosuke, forcing the wounded Hashira to block him as his power continued to grow. Giyu ordered the survivors to kill Tanjiro, but Nezuko ran onto the battlefield and cried out to her brother.

• Demon King Tanjiro unleashed bone whips at Zenitsu and Inosuke, and Kyojuro and Giyu barely managed to cut them down.
• Tanjiro picked up a Nichirin Blade and took a Sun Breathing stance, combining demon powers with Breathing Styles.
• Giyu decided Tanjiro was no longer himself and ordered everyone still able to fight to kill him, even if they died doing so.
• Zenitsu and Inosuke struggled to raise their swords against Tanjiro, while Kyojuro resolved himself to fight.
• Nezuko broke past the Kakushi and ran toward Tanjiro, crying out, "Big Brother!"

Nezuko confronted Demon King Tanjiro and pleaded with him to come home, reaching the part of him still connected to his family. Tanjiro stopped his attack and shed a tear of blood, revealing his first falter and giving the others a faint glimpse of hope.

• Nezuko rushed toward Demon King Tanjiro despite Giyu Tomioka and Kyojuro warning her to stop.
• Tanjiro slashed at Nezuko, but his claw halted just short of her forehead.
• Nezuko touched Tanjiro's face and tearfully urged him to go home to their waiting family.
• Tanjiro trembled as Muzan's desire for destruction fought against his instinct to protect Nezuko.
• Tanjiro shed a tear of blood, showing that Nezuko's plea had made him falter.

Demon King Tanjiro’s agony revealed that his consciousness was still resisting Muzan’s influence. After waking, Uesugi Sasuke saw Tanjiro’s soul fighting Muzan’s echo and urged Giyu Tomioka not to kill him, leaving the Demon Slayers facing an impossible choice.

• Demon King Tanjiro roared in agony as his unstable aura and Bone Whips tore up the battlefield while avoiding Nezuko.
• Kyojuro Rengoku realized Tanjiro’s consciousness might still be present, but Zenitsu asked what they could do.
• Uesugi Sasuke woke and used his Eternal Mangekyō Sharingan to see Tanjiro’s soul resisting the chains of Muzan’s energy.
• Sasuke told Giyu Tomioka that killing Tanjiro would fulfill Muzan’s final wish by destroying Tanjiro’s soul along with his body.
• Giyu understood that sparing Tanjiro risked the world, while killing him would condemn their companion’s soul.

As Demon King Tanjiro’s rampage grew more dangerous, Sasuke proposed entering Tanjiro’s mental world to help him resist Muzan’s will. He asked his exhausted companions to hold Tanjiro off while he attempted the desperate plan.

• Demon King Tanjiro fought chaotically against the struggle inside him, while Kyojuro Rengoku warned that everyone was nearing their limits.
• Sasuke told the others he could enter Tanjiro’s mental world and interfere with his soul to help him fight Muzan’s will.
• Giyu Tomioka objected because Sasuke was too injured to withstand the technique, but Sasuke insisted it was their only way to save Tanjiro.
• Sasuke reflected on the bonds that had changed him and realized he did not have to face the battle alone.
• Sasuke bowed to his companions and asked them to hold Tanjiro off while he tried to bring their family back.

Sasuke asked the survivors to help him reach Tanjiro’s Mental World, but the wounded fighters doubted they could stop the Demon King. Kanao used her final Flower Breathing form to see the human light within Tanjiro and rushed toward him with the last demon-to-human medicine, but his repulsive force threw her back and sent the syringe flying.

• Sanemi rejected Sasuke’s plan and urged the survivors to cut off Tanjiro’s head before he mastered his power.
• Kanao remembered Shinobu’s words and Tanjiro’s kindness, then activated Equinoctial Vermilion Eye at the cost of her eyesight.
• Kanao saw a faint, sun-warm light bound by black chains inside Tanjiro’s heart and declared that Tanjiro was still there.
• Kanao charged Tanjiro with the last dose of medicine that could turn a demon human.
• Tanjiro’s repulsive force hurled Kanao away and knocked the syringe from her hand, but a bolt of golden lightning streaked toward it before it hit the ground.

Zenitsu saved Kanao and the medicine from Tanjiro’s attack, while Inosuke tried to reach Tanjiro by calling on their shared battles. Tanjiro hesitated, creating an opening that Sasuke urged Kyojuro Rengoku and Giyu Tomioka to exploit.

• Zenitsu used Thunder Breathing to catch Kanao and snatch the medicine before it hit the ground.
• Tanjiro launched his bone whips at Zenitsu, but Inosuke interrupted him by attacking his legs and shouting for him to change back.
• Tanjiro stiffened at Inosuke’s words, and pain and bewilderment deepened in his human eye.
• Sasuke spotted Tanjiro’s opening and told Kyojuro Rengoku and Giyu Tomioka to stake everything they had.

Kyojuro Rengoku restrained Demon King Tanjiro with his final Flame Breathing technique while Giyu Tomioka protected Sasuke with Dead Calm. Their sacrifice gave Sasuke a clear path to Tanjiro, and Sasuke prepared to use his Rinnegan.

• Kyojuro unleashed Flame Breathing, Ninth Form: Purgatory, and bound Tanjiro in a dragon of flame.
• Giyu used Water Breathing, Eleventh Form: Dead Calm, to neutralize Tanjiro's shock waves and shield Sasuke.
• Sasuke crossed Giyu's sanctuary and approached the immobilized Tanjiro.
• Sasuke aimed his Rinnegan at Tanjiro's forehead and said he would take it from there.

Sasuke entered Tanjiro’s inner world and found his soul bound and nearly consumed by Muzan’s will. Muzan threatened to take Tanjiro’s body and use it to destroy the people he loved as he attacked Sasuke.

• Sasuke touched Tanjiro’s forehead and found himself transported into a corrupted inner world.

• Muzan declared himself god of the inner world and sent black blades of malice at Sasuke’s soul.
