>>41669989>>41662134Here's some culture for you both. There is a youkai called FutaKuchi-Onna(Two-mouth-Woman), that has an extra mouth on the back of its head.
As youkais usually do, they trick humans, and this one looks like a regular woman to fool their prey. Mawile is clear reference of this because of its japanese name "Kucheat" that reads similar to "Kuchi".
