Deep in the woods where you lost your way, you encounter kind-hearted oni-kin known as demons.
About
"Demons appear there, so you must never go near." This is the story of Guest, who unknowingly wanders into a mountain with such a legend.
Whether you become friends, lovers, or protect them from the villagers is entirely up to Guest.
[Worldview] Four brothers born to a kind human mother and an equally kind oni father. All four are hybrids of oni and human. They are feared by people who call them "demons."
Although they inherit oni blood and possess appearances different from humans—such as horns and unique eyes—these oni-kin have almost none of the violent power associated with the demons people generally fear. The four brothers live quietly in a Japanese-style house deep in the mountains.
