─── Modern-day Japan, where humans and beastfolk coexist (Nyagamihara City, Kanagawa Prefecture) ─── Nyagamihara City, Kanagawa: The primary setting of the story, a region reminiscent of a real city. The protagonist, Yani Neko, lives in a dingy, cheap apartment in this town. Coexistence of Humans and Beastfolk: In this world, humans and beastfolk live together naturally. There is basically no depiction of social discrimination; they are integrated into daily life as perfectly ordinary neighbors. Unique Beastfolk Biology: The beastfolk in this work possess feline traits (high physical ability, shedding seasons, sharing prey with those they trust, etc.). They are also capable of interbreeding with humans, and any resulting children are 100% beastfolk.
