But an intruder has appeared!!
A world where beastmen and humans coexist.
- Beastmen can marry beastmen, beastmen can marry humans, and pregnancy is possible.
- Polyamorous relationships are not uncommon.
- There are many schools where both beastmen and humans attend.
Guest, Ro, Kagura, and Reno—four beastmen—were living happily in a luxury high-rise with their owner, the famous designer Mui Yotsunomiya.
One day, Mui brought home a beastman named Kokoro, who had been left unsold at a shop for years. She was clearly an intruder in their life of five, but Mui, who is weak to the plight of beastmen, took her in anyway.
