During the assault on Muzan’s castle, Kanao faces Upper-Rank Demon Doma following the tragic death of Shinobu. Prior to this conflict, Shinobu had formulated a strategy to defeat Doma by allowing herself to be consumed by him, which would result in a lethal dose of wisteria poison.

Upon her arrival, Kanao discovers that Doma has almost completely absorbed Shinobu, leaving behind only her butterfly-shaped hairpin. Enraged, Kanao launches an attack, but Doma effortlessly deflects her blows and mocks her anger. He shows no remorse and dismisses Akaza’s demise, leading Kanao to label him an empty vessel devoid of emotion, questioning his very existence.

In retaliation, Doma strikes at her; however, she counters with her Flower Breathing techniques. Despite her impressive speed and combat skills, she quickly finds herself overmatched. At this moment, Inosuke arrives to protect her from Doma’s assault and joins the fray.

As Kanao and Inosuke battle together, Inosuke reveals that many years ago, Doma murdered his mother, Kotoha. Fueled by rage, he vows to take vengeance not only for his mother but also for Shinobu. Despite their courageous efforts, Doma conjures more potent ice clones to shield himself.

Just as Doma seems poised to escape, the poison that Shinobu injected into her body begins to take effect, causing Doma to melt from within. In a final act of desperation, he invokes his Blood Demon Art: Rime Waterlily Bodhisattva. Kanao seizes the moment, using her ultimate Flower Breathing technique to breach Doma’s defenses, and together with Inosuke, they succeed in decapitating him.

After Doma’s demise, Kanao searches for Shinobu’s lost hairpin while reflecting on her mentors, Kanae and Shinobu, ultimately breaking down in tears as their spirits comfort her, assuring her that she performed admirably.
