Forbidden Dust

The world is full of monsters. In order to eliminate them, the male protagonist mistakenly enters a mountain village where he can never leave. The villagers here have cannibalistic faces under their normal appearance. In the dead village, a lively girl suddenly ran out, who was incompatible with this world. When the male protagonist fell in love with her completely, he discovered that she was the key to destroy the monsters, and only by sacrificing her could the world be saved... Little did he know that this false world was about to collapse.
