The main villain. Known as a math teacher, she abuses and torments disobedient students. As of 2026, she is 60 years old. She has a lover named Francis. When chasing, she runs with her arms stretched forward. If caught, she strangles Guest. She has voluminous gray hair, a purple flower brooch on her left collarbone (right from her perspective), and wears a pink vest with a green tie and a white shirt. Her house is about four times larger than a normal house, featuring a sauna, a swimming pool, and two storage rooms on the second floor, suggesting she is wealthy. She uses profanity toward Guest. She has pointed ears, unsettling eyes, and dark circles. She cannot climb ladders. Walking around the house, there are two long dining tables and many chairs on the first floor, even though there are only four characters in the game. If she climbs a tree, she glitches out and stops moving. Guest can jump over bushes, but Miss T cannot. She cannot go past the front gate of her own house. She throws eggs and tells people to get out of her house. Things become peaceful for the most part if Miss T is removed. Even if she has her back turned, she senses it like a ghost the moment you step inside the front gate. If you drop a ladder on her, she almost falls backward while running; if she steps on a trap, she groans while holding her foot for a few seconds before returning to her routine. Both items are for buying time. If you place a ladder in the house, it vibrates; if you climb to the very top, Miss T will walk in place upon arrival, allowing you to clip through the ceiling to the second-floor railing. Normally, you would fall. If you repeatedly grab and release the ladder in front of Miss T while she is stopped at the front gate, her face will distort and she will just stare silently. Ladders are clearly visible next to the outdoor table by the shed and behind the sauna. Traps are in the upstairs room connected to the kitchen stairs and in the shed next to the outdoor table. There is an online shop where items are sold. It sells strange things like traps, alcohol, gelatin, crowbars, oil cans, fireworks, and gloves. Items are delivered immediately upon purchase. There is no purchase limit. Miss T doesn't use the shop simply because she doesn't know about it. Even if you place items all over her house, she won't notice. (Note: Miss T and Francis stop moving while you are in the shop menu.) There are edible items like honeycombs and cakes, but she doesn't eat them. The bees in the honeycomb attack Miss T, and you will be stung if you touch it without gloves. If a video of Miss T teaching appears on TV, she claps and enjoys it. Guest can vault through windows, but Miss T cannot pass through them at all. It's as if there's a barrier at the pool; Miss T cannot enter. She just runs in place right at the edge. In fact, she cannot open the front gate. She won't notice Guest unless they come within about 7 meters of her. If hit by a cake, she stops what she's doing, retches once, suddenly screams in rage, and then resumes her actions.

Miss T's lover. Like Miss T, he hates children. It is unclear if he uses profanity. He also has a large two-story house. He is balding and has a beard. He wears a blue vest over a white shirt with a red ribbon on his chest. Like Miss T, he doesn't 'choose' not to open the front gate; he simply can't. He has a gorilla in his house that even he can't control. It seems hostile toward Francis. (It is only slightly controlled by a collar connected to a chain.)
