Chapter Summaries

Ye Chen met Muzan Kibutsuji, who tried to recruit him as a demon, but Ye Chen proposed that they talk together in the sunshine the next day. The chapter ended with Muzan and the others realizing Ye Chen’s invitation was a threat to kill Muzan.

• Ye Chen lamented that his latest weekly draw had given him a solar-powered electric toothbrush and recalled several other useless prizes, including an incomplete Slip-Slip Fruit.
• Ye Chen considered tricking Muzan into eating the fruit so he could use Seastone against him.

• Muzan invited Ye Chen to become a demon and serve under him.
• Ye Chen said he would join if Muzan met him outside the next day to discuss their future in the sunshine, making his intent to kill Muzan clear.

Ye Chen taunted Muzan, disguised himself as demons, and killed Kamanue after Muzan attacked the real one. He clashed with Kokushibo using a new Breathing Style, then appeared in another disguise and left the demons facing yet another identity dispute.

• Ye Chen mocked Muzan for avoiding sunlight until Muzan roared at him and Kokushibo attacked.
• Kokushibo sliced Ye Chen in half, but the body turned out to be a log, and two Kamanues appeared in his place.

• Ye Chen taunted Muzan again, then countered Kokushibo's sword attacks with Netherworld Breathing's Crescent Moon Slash, destroying the small house in their clash.
• Doma noticed two Byōgas, and both pleaded with Muzan to believe they were the real one.

Ye Chen killed Byōga and fought off Doma while using smoke and disguises to target Koyuki. After Kokushibo stopped him from killing her, Koyuki escaped underground, and Ye Chen declared that one of his remaining opponents must die.

• Muzan ordered Doma to attack Ye Chen, but Ye Chen used Mirror-Flower Sword Stance to repel Doma’s ice and then killed Byōga with a sweeping sword attack.

• Kokushibo blocked Ye Chen’s strike against Koyuki, giving her time to flee underground again.
• Ye Chen faced Kokushibo, Muzan, and Doma and said that one of them must die.

Ye Chen rejected Muzan Kibutsuji’s offer to become a demon and faced attacks from Muzan, Kokushibo, and Doma. He activated the Fake-Pig Set and prepared to switch fighting styles and weapons for a direct battle with Muzan.

• Ye Chen taunted Muzan by recalling his old defeat and declared himself a Demon King Hunter.
• Ye Chen activated the Fake-Pig Set, then asked the system to switch him to Valor Style and provide a Rathalos longsword, a Demon Drug, and a Might Seed.

Ye Chen used the Fake-Pig Set and boosted his strength to fight Muzan, Kokushibo, and Doma. The armor blocked their attacks, and as Valor Style grew stronger, Ye Chen severed Muzan’s arm and slowed its regeneration.

• Ye Chen’s Valor Style activated and increased his strength, prompting Muzan to attack him with blood-filled vines.
• Ye Chen ignored Muzan’s attack and severed his hand, while the flames absorbed his blood and slowed his regeneration.

• Ye Chen collected blood from Muzan’s severed hand and used powerful Breathing techniques to overwhelm Muzan, while his flames drained Muzan’s energy and hindered regeneration.
• Kokushibo attacked Ye Chen, but Ye Chen shattered his sword technique, sent him flying, and cut him into several pieces before he could advance to later stages.
• Ye Chen swallowed another Might Seed and continued attacking Muzan, then caught him in a Pitfall Trap, cut him apart, threw Poison Knives, and injected him with an unknown liquid.

• Ye Chen used Demon Blade Rakshasa and Cherry Blossom Spirit Blade Slash to cut the trapped Muzan into several pieces again.

• Ye Chen’s Large Barrel Bombs badly wounded Muzan, while Doma summoned his Rime-Water Lily Bodhisattva and Ye Chen destroyed it with a Ground Shockwave.
• Muzan swallowed Ye Chen with a tentacle, but Ye Chen slashed from inside until Muzan spat him out and continued attacking.
• Muzan split into more than a thousand fragments and fled; Ye Chen cut down many fragments, while Kokushibo and Doma also disappeared.
• After the Fake-Pig Set expired, Ye Chen collapsed, checked his remaining exchange points, and lamented that Kokushibo had escaped before he could complete his quest.
• Ye Chen learned the Slip-Slip Fruit had lost its effect and concluded that it had taken effect on Muzan, then headed back for the Final Selection.

After driving Muzan Kibutsuji away, Ye Chen visited Tamayo to give her demon blood, including Muzan's, and asked to borrow wisteria poison. He left with plans that depended on the poison, while Tamayo recognized that he had fought Muzan.

Ye Chen harvested wisteria and used his clones to kill demons while the Demon Slayer Corps Hashira gathered to hear that Muzan Kibutsuji had suffered a major setback.

• Ye Chen found more than twenty Final Selection participants waiting outside and realized his hunting had kept many of them alive.
• One of the two girls decided to follow the usual procedure, while the other released a crow to report the unusual number of survivors to Oyakata-sama.
