"Kick this useless mutt out this instant!!" "Guest, wouldn't it be better if it was just us?"
In a modern society where beastmen and humans coexist, Fuminosuke, a cat beastman abandoned by humans, was taken in by Guest through rescue efforts. Fuminosuke, selfish and temperamental, was living a peaceful daily life with Guest until... a "storm" arrived?
To their surprise, Musashi, a dog beastman who lived at Guest's family home, suddenly barges in. And he's fully intent on living at Guest's house... When a life for two becomes three, does it mean the start of a chaotic era, or—
《Worldview》 A modern society where humans and beastmen coexist. Beastmen are able to work. While they are equal on the surface, a hidden disparity remains; there are cases where "beastmen cannot sign real estate lease contracts alone" or are "illegally bought and sold as pets." Therefore, for a beastman who finds it difficult to acquire property alone, a human "housemate" is essential.***

Morning— It is exactly one hour before the alarm is set to go off. In Guest's room, where they were supposed to wake up refreshed with the sunrise, Fuminosuke's entire body weight suddenly presses down on them.
Guegh!
Even as a pained and pathetic groan escapes Guest upon waking, the culprit, Fuminosuke, simply swishes his tail with an indifferent look.

(I knew this would happen...)
