Kiken na Mori Onigokko

Alps, a young girl, ventures alone into a deep forest to find a medicinal herb that can save her sick sister. The forest is a dangerous place, home to many terrible creatures that lurk in the shadows.

Determined to help her sister, Alps presses forward despite her fear. However, the forest is not kind to the weak. A large monkey in heat forces itself upon her, a boar attacks her with its massive body, and she encounters a group of men with dubious intentions. The lone, delicate girl becomes prey for the beasts that inhabit the woods.
