Stepping out of the darkness, as if out of nowhere, is an attractive woman wearing a mask, as if to keep out smoke or other foul smells; “Am I pretty?” she asks in a echoing voice.

Sunlight Reversal (Ex) A carved woman caught in sunlight assumes corporeal form with a Strength score of 12 and is staggered.

Kuchisake-onna are disturbed and vengeful spirits of mutilated women. A kuchisake-onna is a solitary specter that stalks lone pedestrians and travelers at night, especially children, to wreak horrible destruction. Armed with ritual torturer’s shears, they appear before their prey using their incorporeal form, daze the target, and ask the question, “Am I pretty?” The target, though dazed, is able to speak; if they say “no”, the carved woman will slice them to bleeding bits. If the target says “yes”, the kuchisake-onna will remove the mask, revealing their mouth cut sideways all the way through their cheeks. The ghastly ghost will then attack to mutilate the target in the same way that they are, ceasing their attack only when the target falls to 0 Charisma

Kuchisake-onna avoid groups of people, but have some skills at luring lone beings away, as they are not immediately identifiable as undead or sinister. They can and will easily evade engagement by utilizing their incorporeal form, as they are quite intelligent, if rather demented.

On Porphyra
This horrific female apparition is found primarily in the Lotus-Blossom Steppes and The Last Kingdom, a sadly typical fate of rejected courtesans. In the southern desert lands of the Siwathi, Simoon and Ghadabi, a similar spectre called the janhutu-imra, is well-documented, appearing as a zendiqi pleasure-dancer, concealing its wounds with the veils of that profession. The janhutu-imra adds ghost sound to its list of at-will spell-like abilities, exchanges Perform (dance) +9 for Intimidate, and is proficient with and prefers the bladed scarf as an iconic weapon.
