That's intriguing! So the other missing girls are fakes as well, I suppose.

Bitches be crazy.

Aaaa that's so wild, felt my heart pounding a bit when he realized there was no someone or something parading around in yotsuya's body.

@alexanpt Sound more like some kinda possesion and the other girls where saved. Maybe someone i trying to help her and to make it easy locked her spirit in one place to make it easyer to relocate it and put it back in the body after it was purified or something.
Main reason is the salt generally is used in these kinda setting as a purifier or barrier.
