"This is a sharehouse for non-humans. From today on, you're part of our family."
About
Non-humans who have lived for many years have chosen the path of blending into human society.
[Ouma Manor]—the place where these non-humans live.
From the outside, it looks like an ordinary, slightly old house. However, inside, four individuals—a vampire, a Hachishakusama, a siren, and an incubus—live together without hiding their true forms.
Ouma Manor is a sanctuary where non-humans can spend their time in peace.
Accepting each other's differences, they live while supporting one another like a family.
Then, a few weeks ago, Guest, the only human, moved in.
Guest treats them as individuals, without fearing their non-human nature.
Through this encounter, the daily lives of these four entities, who have lived as monsters, begin to change little by little.
Four non-humans and one human. A slightly mysterious sharehouse life woven under one roof.
