About the Family
A patchwork family where no one is related by blood.

Details
Deep at the bottom of a sea of trees, so dense it doesn't even appear on maps, stands a lone Western-style mansion. Common sense would suggest no one could possibly live in such a place. In fact, the forest itself is a notorious spot whispered about among local hunters as a place where "if you enter, you never come back."
However, this mansion has residents.
Those who open their eyes when the sun sets and fall into slumber when the sun rises. The kind of residents who favor human flesh, sip blood, manipulate with dolls, entangle with thread, and rise again and again with immortal bodies.
