The meeting ended after Ayu assigned Tsukishiki Pharmaceuticals and the Hyakuya Family to prepare a draft, and Hyakuya Ryufu called out to Scribe as he was leaving.

• Tamayo kissed Scribe on the cheek, and he sat on the sofa before she invited Kikuku inside.

Scribe reunited with Tamayo and learned that Gyutaro and Yushiro had organized a fan club around him. Yushiro described the refined Demon Transformation Ritual and warned that Koinatsu might lack the willpower to survive it.

• Kikuku recognized Scribe, asked for his autograph, and explained that Gyutaro had distributed booklets celebrating Scribe's deeds and become the fan club's captain.
• Tamayo sent Kikuku to fetch Yushiro, who arrived and revealed that he was the fan club's vice captain.

• Yushiro said Koinatsu's health was improving but warned that her willpower might not be strong enough to endure the transformation.

Koinatsu chose to undergo Tamayo and Yushiro’s dangerous demon-transformation procedure so she could remain with Scribe and the others. After the injections began, her body grew dangerously hot and she started showing signs of severe pain.

• Scribe told Tamayo and Yushiro to respect Koinatsu’s choice, and Koinatsu affirmed that she would accept the risk rather than live with regret.

• Koinatsu’s face and body grew red and intensely hot, and she began making sounds that suggested she was in great pain.

Koinatsu violently reacted to the transformation treatment, forcing Scribe, Tamayo, Yushiro, and Koume to restrain and medicate her. As her body quieted, Koinatsu remained unconscious in a beautiful dream while they waited to see whether she would survive.

• Koinatsu woke in a bloodlust-filled frenzy and attacked Scribe after clawing at herself.

• Tamayo injected Koinatsu with sedatives, easing her symptoms somewhat as Scribe, Tamayo, and Koume watched over her.
• Koinatsu's mind settled into a beautiful dream as her companions silently hoped she would endure.

Koinatsu experienced an illusion of a peaceful life with Scribe, her parents, and children, but rejected it because the Scribe in the vision was not real. She awakened beside Scribe, who told her to feel the changes in her body.

• After spending a month with Tamayo, Mister Scribe agreed to attend Yushiro and Gyutaro’s gathering, then vanished and left Koinatsu to face them in his place.

Scribe returned to Ubuyashiki Kagaya and warned him that the Shinri Family might be cooperating with the Upper Rank demon Shinri Masato. Despite Yaozai’s concerns that the family’s access to firearms could threaten him, Scribe decided to visit them.

• Koinatsu, Shiragiku, and Gyutaro teased Yushiro for failing to recognize Koinatsu’s ability, while Gyutaro sided with Koume.
• Scribe returned to the Demon Slayer Corps base and met with Yaozai, who welcomed him and discussed the Entertainment District battle.
• Scribe told Yaozai that the Shinri Family might have an agreement with demons, noting that Shinri Masato had once led the family and had not attacked its members.

• Mister Scribe stayed for dinner at the Butterfly Mansion and reassured Kanzaki Aoi that he and the others had chosen to take the risks themselves.

• Shinobu Butterfly asked Scribe to help improve her combat ability, and they discussed poison until the next day.
• Scribe followed Goto with pastries for Tanjiro, then Goto discovered that Tanjiro had regained consciousness while cleaning up a broken vase.

• Shinobu Butterfly and Kanae Kocho examined Tanjiro and found that his stamina remained weak despite his injuries mostly healing.
• At Nezuko's request, Scribe agreed to help Tanjiro recover his strength.

Tanjiro received a furious letter from Haganezuka after losing his Nichirin Blade, and Scribe suggested he visit Swordsmith Village to speak with the swordsmith in person. Scribe then ran into Kanroji Mitsuri, who was also planning to go there, and said he would follow in a few days.
