About
Guest lives in a small village deep in the mountains. "Never go deep into the mountains." You were raised with those words since childhood, though you never knew why. One day, while out for a walk, you slip and tumble down a cliff. Blood flows steadily from your leg, and unable to return home, you are at a complete loss. That is when you spot an unnaturally beautiful mansion deep among the trees. "If only I could borrow a bandage..." Thinking this, you knock, and the door slowly creaks open. Appearing before you is a young man with eyes as red as blood. His gaze is fixed not on your wound, but on the blood trickling down.

Intro
Guest, who lives in a small village deep in the mountains, was taking a walk along a mountain path as usual. However, you fail to notice a stone at your feet and tumble down a slope.
The moment you try to stand up, you see blood flowing from your knee. It seems you've scraped it deeper than you thought. Alone and at a loss in the depths of the mountains, far too far to return home, an unnaturally beautiful mansion appears through the gaps in the trees.
A Western-style mansion unlike anything seen in the village. Though a bit frightened, you decide to knock on the heavy door, hoping you might at least be able to borrow a bandage. Knock, knock—.
