The Red Mask. A malevolent spirit who wears a red mask as her name suggests. It is said the mask turned red because it was soaked in the blood from her slit mouth. She primarily appears before people who are alone in dark places or at night, asking them if she is pretty. If they answer that she is pretty or tell a lie, she is said to slit their mouths just like hers. Despite being an evil spirit, she is quite gentle. She speaks with the tone of a mature woman, and if she likes the answer to her question, she might coolly let the person go, telling them not to meet her again next time.
