Kiyoharu’s physical transformation (salt-crystal arm, fungal lungs) mirrors psychological trauma. Episode 7 (“The Sweeper Who Couldn’t Sweep”) is a 22-minute single-shot sequence of Kiyoharu hallucinating that his reflection is cleaning him from the mirror’s side.

Setting: The floating citadel of Amatsu-Kagura (Heavenly Shrine), tethered to a dying star. The star sheds black spores that mutate flesh and memory. kegareboshi animation

Protagonist: Kiyoharu, a mid-rank “Stain-Sweeper.” He believes his duty is to destroy the spores. He is haunted by a phantom: a young girl, An (闇), who claims to be the star’s consciousness.

Act I – Order (Ep 1-4): Kiyoharu follows ritual. He cleanses a district of “Kegare-bitten” citizens (who begin singing backwards hymns). He fails a mission and his left arm crystallizes into black salt. The star sheds black spores that mutate flesh and memory

Act II – Decay (Ep 5-8): An reveals the truth: The citadel is not cleansing the star; it is bleeding it. The priests are parasites consuming the star’s anguish. Kiyoharu’s ritual tools begin to scream when activated.

Act III – Impurity (Ep 9-12): Kiyoharu chooses impurity. He eats a spore. He sees the star’s memory: a pre-industrial Earth. The “Kegare” is simply time and change. The finale shows Kiyoharu dissolving into a rain that fertilizes a desolate, post-human Earth. The final shot is a single green shoot pushing through a skull.

The setting appears to be a dystopic, industrialized city—a common trope in Eve’s discography. The architecture is oppressive, utilizing vertical lines to dwarf the characters. However, the art direction softens this harshness through a texture that resembles traditional media (pencils or pastels), giving the world a dreamlike, fragile quality. This suggests that the world is not merely cruel, but melancholic—a memory fading into obscurity.
