In a post-apocalyptic world, beings cloaked in pitch-black feathers and masks descend from the sky to carry out a grim mission: eliminate every living creature that has defiled nature so that a pristine world may be restored. When the nameless protagonist fails in their task and is on the verge of death, their life is saved by none other than a creature that was marked for extermination. This inverted predator–prey encounter forms the core of Noah no Karasu, the opening story of a seven-piece collection that explores beauty lurking in shadow and the fragile bonds forged in hopelessness. The anthology moves through a range of speculative settings: the post-war aftermath of Kuni Yaburete, a swamp princess and a foolish young man in Numahime to Houtarou, a tale of a mermaid and a fisherman in Ningyo to Tsuribito, a cursed blade in Ryuukoutou, and a well that exacts a heavy price in Taika no Ido. Each story stands alone, yet they are tied together by an atmospheric tension between light and what spreads its wings just beyond it, painting moments where despair gives way to unexpected connection.
