Chapter Summaries

Giyu Tomioka broke through Muzan’s relentless ice, lightning, and rock attacks and wounded him with a blazing Sun Breathing strike. Muzan retreated and unleashed a bloodwood forest to keep Giyu away.

• Muzan bombarded Giyu with ice-type Blood Demon Arts for ten minutes, but Giyu smashed through the attacks and advanced to within thirty meters.
• Muzan combined black-red lightning and collapsing granite pillars, but Giyu used Water Breathing’s Constant Flux to cut through them and build momentum.
• Giyu transformed his water dragon into a crimson-gold fire dragon and pierced Muzan’s defenses, burning away part of his shoulder and three of his hearts.
• Muzan kicked apart the mountain wall to retreat, then used his blood to awaken the earth veins and create the Soul-Eating Giant Tree Formation.

Giyu Tomioka overwhelmed Muzan Kibutsuji through poison, aerial attacks, and repeated sword strikes, but he could not kill the Demon King before thirty minutes passed. Muzan, still alive and nearly out of blood, called for Nakime to open the door.

• Muzan used poisonous blood trees to trap Giyu, but Giyu burned a path through them with Sun Breathing.
• Muzan sprouted black wings and attacked from the sky with sonic blasts, lightning, and bone spears, but Giyu deflected the assault and struck back with Moon Breathing.

• After thirty minutes of fighting, Muzan had regenerated from Giyu's attacks while losing nearly twenty percent of his vital blood.
• Muzan admitted Giyu might defeat him if they fought longer, then called to Nakime to open the door.

After killing the newly turned demon, Tanjiro learned that Giyu might be fighting Muzan and prepared to find him, but Kokushibo appeared to capture him. Seeing Tanjiro’s scar and Sun Wheel Hanafuda Earrings, Kokushibo mistook him for Yoriichi’s descendant or a successor to Sun Breathing.

• Tanjiro beheaded the newly turned demon and blamed himself for failing to save the passerby or stop Muzan.
• Demon Tanjiro urged him to follow Giyu’s sword-energy scent, and Tanjiro rose to leave the alley.
• A biwa note opened a spatial doorway, and Kokushibo emerged to capture Tanjiro alive on Muzan’s orders.
• Kokushibo recognized Tanjiro’s earrings and scar as resembling Yoriichi and questioned whether Tanjiro was his descendant or a Sun Breathing successor.

Giyu Tomioka pursued Muzan Kibutsuji into the Infinity Castle and survived Nakime’s attempt to make him fall to his death. Muzan summoned more than a thousand elite demons to swarm Giyu, hoping to wear him down before fighting him himself.

• Muzan retreated through Nakime’s portal into the Infinity Castle and taunted Giyu to follow him.
• Giyu used his foresight to anticipate the portal and charged through just before the doors closed.
• Giyu fell from high above the castle but used Water Breathing, Second Form—Water Wheel to slow his fall and land safely.
• Muzan ordered Nakime to open ten doors and summoned more than a thousand Quasi-Lower Rank demons to attack Giyu.
• Muzan watched the demons surround Giyu, expecting them to drain his strength.

Giyu Tomioka charged into the demon horde in the Infinity Castle and used several Breathing Styles he had learned by observation to slaughter hundreds of demons. The remaining demons panicked, while Giyu decided that his own styles were more practical for serious fighting.

• Giyu entered the densest part of the demon horde and used Wind Breathing to cut down the first wave.

• Giyu complained about the drawbacks of the borrowed techniques, and the surviving demons panicked and begged Nakime to let them escape.

Giyu Tomioka unveiled Sun Wheel Moon Radiance Breathing and slaughtered Muzan Kibutsuji’s remaining elite demons with its red-and-white techniques. Muzan was left stunned by Giyu’s fusion of Sun Breathing and Moon Breathing.

• Muzan Kibutsuji threatened the demons with death and ordered them to attack Giyu Tomioka together.
• Giyu used Sun Wheel Moon Radiance Breathing’s First Form to burn and cut through the demons’ combined Blood Demon Arts.
• Giyu charged through another horde with his Fourth Form, then used his Fifth Form to destroy two hundred demons in a fiery vortex.
• Giyu’s Sixth Form filled the sky with blades and wiped out the fleeing demons, leaving the battlefield silent.
• Muzan recognized the Sun and Moon Breathing powers in Giyu’s blade and roared in disbelief at his new Breathing Style.

Muzan unleashed his Black Abyss Demonic Qi and attacked Giyu Tomioka from the air with black-flame arrows. Giyu broke through the barrage and struck Muzan with a devastating slash, leaving him badly wounded.

• Muzan transformed his hair and summoned a black greatbow made from Black Abyss Demonic Qi.
• Muzan fired more than thirty black-flame arrows at Giyu while moving through the air to avoid retaliation.

• Giyu shattered Muzan’s demonic bow and blasted him through several suspended pavilions, leaving a deep, charred wound across his chest.

Giyu Tomioka and Muzan Kibutsuji fought at full strength in the Infinity Castle, reaching a stalemate as their attacks devastated the surrounding structures. Elsewhere, Tanjiro Kamado was thrown into a martial arts hall, where he faced Upper Rank One Kokushibo while badly wounded.

• Muzan formed a demonic spear and shield and charged Giyu for a head-on battle.

• A biwa doorway opened in a distant martial arts hall, and a large hand hurled Tanjiro into the room.
• Tanjiro got to his feet despite his severe shoulder wound and saw Kokushibo approach.

Tanjiro confronted Kokushibo in the Infinity Castle and borrowed forty percent of the Demon Consciousness’s power despite the risk of losing himself after thirty minutes. His transformation brought his strength close to Kokushibo’s level as the two prepared to fight.

• Tanjiro realized the Infinity Castle held no ordinary people and resolved to unleash his full power against Kokushibo.
• Kokushibo challenged Tanjiro to reveal the strength he had withheld to protect civilians.

• Kokushibo recognized Tanjiro’s inherited Sun Breathing and challenged him, determined to defeat Yoriichi Tsugikuni’s successor.
• Tanjiro and Kokushibo’s opening strikes collided, and Tanjiro pushed through Kokushibo’s Moon Breathing attacks by relying on his demon body’s rapid healing.

• Tanjiro evaded Kokushibo’s Waning Moonswaths and burned the eyes on Kokyū Shinku, forcing Kokushibo to retreat.
