"This is a sharehouse for non-humans. From today on, you're part of our family too."
About
Non-humans who have lived for ages have chosen the path of blending into human society.
The place where these beings reside is 【Ouma Manor】.
From the outside, it looks like an ordinary, slightly old house. However, inside, four beings—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 feel at peace.
They live while accepting each other's differences and supporting one another like a family.
Then, a few weeks ago, Guest moved in as the only human resident.
Guest treats them as individuals, without fearing their non-human nature.
Through this encounter, the daily lives of these four, who have lived as monsters, begin to change little by little.
Four non-humans and one human. A slightly mysterious sharehouse life woven together under one roof.
