Chapter Summary: “I Admit You’re All Very Clever”

Key Plot Points and Events

• Ubuyashiki Kagaya explains that his plan to die alongside Muzan is not intended to kill Muzan directly. The explosives are meant to prevent Muzan from immediately regenerating, creating an opening for Tamayo to approach and administer her medicine.
• Yuko objects to Kagaya and Amane sacrificing themselves, arguing that she can likely create the same opportunity herself—possibly even carrying and injecting Tamayo’s medicine into Muzan.
• Yuko also points out that the Demon Slayer Corps would lose its central command if Kagaya and Amane died before the final battle, especially if the fight were drawn into the confusing Infinity Castle.

• Kagaya then explains that Tamayo has agreed to follow Yuko’s approach if Yuko objects to the original strategy. Yuko reluctantly accepts a compromise: she will join the preparations after Hashira training, while Kagaya and the others still plan to lure Muzan into a confrontation and weaken him.
• Kagaya reflects on his earlier conversations with Tamayo. Although Yuko and Tanjiro both represent important hope, Tamayo clarifies that Tanjiro was not the reason she chose to aid the Demon Slayer Corps.

• She also shows confidence in her own abilities, believing she can personally create an opportunity for Tamayo to reach Muzan.
• Kagaya remains calm, strategic, and accepting of death, but he is willing to adjust the plan when Yuko presents a better alternative. His trust in Yuko, Tamayo, and Tanjiro is clear.
• Amane quietly shares Kagaya’s willingness to sacrifice herself, though her reaction shows that she, too, has imagined a future in which the family survives and lives peacefully.
• Kiriya’s introduction emphasizes the exceptional intelligence and premature maturity of the Ubuyashiki children, though his age makes his proposed role troubling even to Yuko.

• Trust and cooperation: The plan depends on the combined abilities of Yuko, Tamayo, Kagaya, and the Demon Slayer Corps rather than on a single hero.

Summary

Key plot points and events

Yuko proposes an extreme treatment for Ubuyashiki Kagaya’s rapidly worsening curse: removing his skin and flesh, possibly even scraping away bone, and using her blood to reconstruct his body. She argues that his condition may soon prevent him from speaking or commanding the final battle against Muzan. Kagaya accepts the procedure despite its horrifying nature, encouraged by Amane’s silent support. Yuko and Shinobu transport him to Tamayo’s laboratory, where he can be treated by both doctors.
At Tamayo’s home, Yuko learns that Tamayo is still studying Yuko’s blood and urges her to focus instead on creating another medicine to weaken Muzan. Tamayo explains that the existing weakening medicine resulted from centuries of research and could not be reproduced quickly. Yuko then asks whether Kagaya’s curse spreads from within and whether her blood could rebuild his body after the infected tissue is removed. Tamayo seriously considers the possibility.

• Kagaya demonstrates courage and determination by consenting to a brutal experimental treatment, prioritizing his ability to lead the Corps and defeat Muzan.
• Amane reveals her deep love and fear for Kagaya, instinctively encouraging him to accept the treatment. She also expresses her hope that they and the others can survive and live happily.

The characters’ hope for a “perfect” ending reinforces the theme that the future is no longer bound to the original tragic path.
