Chapter Summaries

Ye Chen gave Shinobu Kocho an Antidote that removed the toxins she had deliberately injected into herself, then showed her a Light Bowgun and explained how its Poison Ammo could harm demons.

• Kagaya Ubuyashiki suspected Ye Chen's earlier actions had changed Muzan Kibutsuji's plans and ordered another message sent.

Kyojuro Rengoku and Giyu Tomioka traveled to a town near the site of a mass disappearance while Ye Chen and his companions investigated the empty town itself. Ye Chen sensed demons nearby despite Tanjiro detecting no demonic scent, and the group continued deeper into town.

Ye Chen and Tanjiro’s group walked into a demon ambush built around tentacles whose eyes could put people to sleep. Ye Chen and the sleeping Zenitsu fought back, while the others recovered with medicine and prepared to keep fighting.

• Zenitsu clung to Tanjiro and muttered nervously until Ye Chen stopped the group and shot a demon hiding nearby with his Yian Kut-Ku Heavy Bowgun.

• Still asleep, Zenitsu used Thunder Breathing, First Form: Thunderclap and Flash, Sixfold Strike to decapitate six demons and returned to Ye Chen’s side.
• Ye Chen warned Xiao Hua and Redhelm not to look at the eyes, then rejected Zenitsu’s suggestion to attack the tentacles because his instincts told him to avoid the area ahead.
• Ye Chen gave sleep-curing medicine to Tanjiro, Makomo, and Inosuke, then fired his Heavy Bowgun at the demons as the others woke and Zenitsu continued protecting them.

Akaza battled Kyojuro Rengoku and Giyu Tomioka, urging both Hashira to become demons while they defended the townspeople from attacking demons. After Akaza sent them flying, he unleashed his Final Form at both of them.

• Akaza fought Kyojuro Rengoku and Giyu Tomioka, praising their strength and asking them to become demons.
• Giyu Tomioka used Dead Calm to counter Akaza, while he and Kyojuro Rengoku continued attacking him with their Breathing Styles.

• Akaza grew furious that the Hashira prioritized the townspeople and knocked Giyu Tomioka and Kyojuro Rengoku toward each other with powerful kicks.
• Akaza unleashed Destructive Death, Final Form: Blue Silver Chaotic Afterglow at both Hashira.

Ye Chen arrived as Kyojuro Rengoku and Giyu Tomioka struggled against Akaza, then took over the fight while the injured Hashira went to protect civilians. Ye Chen overpowered Akaza with his fists and netherworld fire, leaving Akaza bewildered after urging him to become a human instead.

• Akaza's barrage broke through Giyu Tomioka's and Kyojuro Rengoku's defenses and badly injured them, but both refused his offer to become demons.

• Akaza again urged Ye Chen to become a demon, so Ye Chen argued that demons had limits and told Akaza to become human.

Ye Chen taunted and defeated Akaza, but Akaza overcame decapitation and continued fighting. Ye Chen pinned him with his fire-wreathed Nichirin Blade and set out to drain his energy.

• Ye Chen taunted Akaza while fighting him, then countered Annihilation Type with Hellfire Blast and sent him flying.

Ye Chen pinned Akaza until Kokushibo arrived to rescue him, but then provoked Kokushibo by taking Yoriichi Tsugikuni’s appearance. Kokushibo entered his strongest form to fight Ye Chen, while Muzan watched in terror and Akaza was left wondering why they had abandoned their retreat.

• Ye Chen pinned Akaza and drained his energy, briefly making Akaza see Koyuki and a middle-aged man before he resumed resisting.

• Ye Chen used Demon Blade Rakshasa and Cherry Blossom Spirit Blade Slash to break through Kokushibo’s attack, snap his sword, and slash his body.

Ye Chen forced Kokushibo and Akaza to retreat after Muzan ordered Kokushibo to withdraw, but he could not stop them because they threatened the Hashira and the city. When Kyojuro Rengoku questioned whether Nezuko could be trusted, Ye Chen and Giyu Tomioka both said they believed Tanjiro.

• Muzan ordered Kokushibo to retreat, and Kokushibo threatened to let Akaza kill Giyu Tomioka, Kyojuro Rengoku, and the people in the city if Ye Chen kept fighting.
• Ye Chen let Kokushibo and Akaza leave, then urged the injured Hashira to grow stronger and unlock the Demon Slayer Mark, Transparent World, and bright red blade.
• Inosuke, Tanjiro, Zenitsu Agatsuma, Nezuko, Makomo, Xiao Hua, and Redhelm arrived after the battle had ended.
• Kyojuro Rengoku questioned why Ye Chen was traveling with Nezuko and doubted Tanjiro's claim that she would never eat people.
• Ye Chen and Giyu Tomioka told Kyojuro Rengoku that they believed Tanjiro, leaving Kyojuro stunned.

Kyojuro Rengoku agreed to leave Nezuko’s fate for Demon Slayer Corps Headquarters to decide after Ye Chen and the others defended her. As the group prepared to return, Zenitsu woke up, misunderstood Tanjiro and Nezuko’s relationship, and then learned they would face questioning.

• Ye Chen argued that Nezuko had not harmed anyone, while Giyu Tomioka and the others voiced their trust in her.

• Ye Chen explained that Nezuko was Tanjiro’s younger sister, and Zenitsu immediately apologized and called her his sister-in-law.
• When Zenitsu learned Tanjiro and Nezuko would be questioned, he begged Ye Chen to save them.

Ye Chen used Zenitsu's feelings for Nezuko to persuade him into a staged rematch against Inosuke, coaching him with Pikachu-style commands. Zenitsu's enhanced Thunder Breathing overwhelmed Inosuke, whose swords broke when he failed to block the finishing strike.

• Ye Chen stopped Zenitsu from pestering Tanjiro, then threatened to speak badly of him unless he sparred with Inosuke and followed Ye Chen's instructions.

After Zenitsu defeated Inosuke in a bizarre battle, Ye Chen accompanied Tanjiro to the Demon Slayer Corps meeting to defend Nezuko. When Sanemi attacked Tanjiro, Ye Chen stopped him and challenged the Hashira to prove Nezuko had committed any crime.

• Zenitsu defeated Inosuke after following Ye Chen's commands, and Ye Chen approved of Zenitsu's performance.
• Ye Chen reassured Tanjiro that he would protect him and Nezuko as they headed to meet the Demon Slayer Corps.
• At the meeting, Gyomei, Sanemi, Shinobu, and Obanai expressed support for killing Nezuko, while Tanjiro insisted she had never eaten anyone.
• Sanemi moved to subdue Tanjiro, but Ye Chen caught his hand and argued that Nezuko was innocent unless anyone could prove she had harmed someone.
• Ye Chen overpowered Sanemi and warned the Hashira not to attack without warning before the discussion continued.

Ye Chen defended Nezuko before the Hashira, and Kagaya Ubuyashiki accepted evidence that she had never harmed a human. Sanemi Shinazugawa then tried to test her with his rare blood, which Ye Chen offered to her directly.

• Ye Chen challenged the Hashira to prove Nezuko had harmed anyone, and Giyu Tomioka vouched that she had not eaten anyone while living with Sakonji Urokodaki.
• Kagaya Ubuyashiki read Urokodaki's letter, which said five people would commit seppuku if Nezuko ever hurt a human; Ye Chen denied agreeing to be one of them.
• Sanemi Shinazugawa and Kyojuro Rengoku objected, but Kagaya ruled that Nezuko could not be declared guilty and said her condition might help against Muzan Kibutsuji.
• Sanemi proposed testing Nezuko with his rare blood, and Ye Chen brought out a bowl and kept him away from her.
• Ye Chen brought Nezuko out of Tanjiro's box beyond sunlight and offered her Sanemi's blood, leaving Tanjiro bewildered.

Ye Chen proved Nezuko could resist the temptation of human blood, ending the Hashira’s objections to her. He then proposed that Tanjiro, Zenitsu Agatsuma, and Inosuke join the Hashira’s special training, before asking the System to redeem smithing notes and check his remaining exchange points.

• Ye Chen tempted Nezuko with rare human blood, but she fled from him instead of drinking it.
• Kagaya Ubuyashiki asked whether anyone still objected to Nezuko, and Sanemi Shinazugawa, Obanai Iguro, and the other Hashira accepted that she was harmless.
