Yami Shibai Season 4 Episode 9 English Subbed Episode Title:Grinding Teeth.Episode Description:An office worker, Miwako, is on a trip with her co-worker. The two women don't know much of the tourist spots but they find that enjoyable by itself. They soon come across a spot where the locals don't go: a cave with four Jizo statues with red cloths tied around their necks, one of which has a red string tied around one of its teeth. That night, when the two women go to spend the night at the hotel, Miwako complains of a toothache, a result of her grinding her teeth. Painkillers don't work so she instead calls for a dentist and finds one dentist's office still open. Miwako finds, upon arriving, that the dentist's office seems shady, but the pain leaves her with no choice. She's set in the chair, and the elderly dentist woman takes a look in her mouth; her expression grows dark. The dentist walks over to her assistants and whisper something along the lines of "Don't let her get away" and "It can't be helped" before returning with a pair of pliers, telling Miwako the tooth has to be pulled out. Miwako isn't comfortable with the idea of having her tooth pulled out by these old world dentists and tries to leave but is held down by the assistants. She manages to get away before the dentist tries to pull out the molar. She doesn't even hear the dentist warn her about something regarding the tooth. Back in the hotel, she checks her tooth in the mirror, only for it to pop out on its own. It appears to have an anguished face. Then she remembers the dentist's warning fully: "If you leave like this, they'll come for you!" Miwako looks back at the molar in fear, only to find that it's gone, leaving a trail of blood as though it got up and walked off on its own. She follows the trail to the bedroom her friend is sleeping in and hears a grinding sound. And the closer she gets to her friend, the louder the grinding seems to get...
