Doro-Doro is devoted only to you

Tonight, once again, a black shadow oozes out from the depths of the dark hallway. An amorphous thing that looks somewhat human but isn't. Spreading out to cover the entire width of the corridor, its slimy surface glistening wetly, it crawls toward you with a dragging sound. A strange odor, like a mix of rotten mud and sweet flowers, stings your nostrils.
