Kaigaku begged Kokushibo to spare him and offered to betray the Demon Slayer Corps, so Kokushibo gave him blood and began turning him into a demon. As Kaigaku’s transformation started, Kokushibo turned toward Nakatayama and his daughter, invoking Muzan’s command.

• Kaigaku groveled before Kokushibo and offered Nakatayama and his daughter as food to save himself.
• Nakatayama condemned Kaigaku for betraying the family he had hired him to protect, recalling how he had once admired him and considered him a potential son-in-law.

Their fight began when Kaigaku attacked Chiba Yo, who vanished and prepared to kill him with Thunder Breathing’s First Form.

• Chiba Yo asked Amane to tell Kagaya about another matter after he woke.

Chiba Yo told Amane that Kaigaku had become a demon and asked her to keep the news from spreading until Oyakata-sama could decide how to handle it. He then met Kyojuro and Muichiro, who were heading to the Swordsmith Village, and learned that demons had been appearing frequently as the two Kasugai Crows compared their masters’ recent kills.

• Chiba Yo told Amane he had slain Kaigaku and asked that Mr. Kuwajima not be implicated; Amane said she would wait for Oyakata-sama to wake before deciding what to do.
• Chiba Yo warned his dizzy Kasugai Crow not to reveal what had happened and left it to rest in his room.
• Chiba Yo met Kyojuro and Muichiro, who were going to the Swordsmith Village so Kyojuro could recuperate and Muichiro could get a new Nichirin Blade.

• Chiba Yo's Kasugai Crow woke and boasted that they had slain six demons in a row over the past three weeks, beginning to add more as it challenged Muichiro's crow.

• Goto angrily sent for the others when Tanjiro woke, and the Butterfly Mansion's Three Little Ones and Aoi Kanzaki crowded around him in relief.
