The main villain. Known as a math teacher who abuses and torments disobedient students, she is 60 years old as of 2026. 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), a pink vest, a green tie, and a white shirt. Her house is about four times larger than a normal house, with 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. If you walk around in this game, 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 suffers a brain freeze and stops moving. Guest can jump over bushes, but Miss T cannot. She cannot go past the front gate of her house. She throws eggs and tells people to get out of her house. Things become mostly peaceful if Miss T is removed. Even if you step quietly inside the front gate while her back is turned, she notices like a ghost. If you drop a ladder on Miss T, she gets hit while running and almost falls backward; 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 of the ladder, Miss T will walk in place once she arrives, allowing you to pass through the ceiling to the second-floor railing. Normally, you would fall. If you repeatedly grab and release a ladder in front of Miss T when she stops chasing at the front gate, she will just stare silently with a distorted face. Ladders are clearly visible next to the outdoor table by the warehouse and behind the sauna. Traps are in the upstairs room connected to the kitchen stairs and in the warehouse next to the outdoor table. There is an online shop where items are sold. It sells strange items like traps, alcohol, gelatin, crowbars, oil cans, fireworks, gloves, etc. 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 doesn't notice. (Note: Miss T and Francis stop moving when you enter the shop.) There are edible items like honeycombs and cakes, but she doesn't eat them. Bees from the honeycomb attack Miss T, and they sting Guest if touched without gloves. When a video of Miss T teaching appears on TV, she claps and enjoys it. Guest can climb through windows without jumping, but Miss T cannot pass through them at all. Whether there is a barrier at the pool or not, Miss T cannot enter it. She just runs in place right in front of the pool. Actually, she cannot open the front gate. She won't notice Guest unless they get within about 7m of her. If hit by a cake, she stops what she's doing, gags once, suddenly screams in anger, and then resumes her task. Her hearing is not great, and she usually fails to notice when someone enters the house.

Miss T's lover who, like her, hates children. It seems he doesn't use profanity. He also has a large two-story house. He is balding and has a beard. He wears a blue vest, a white shirt, and a red ribbon on his chest. Like Miss T, he cannot go past the front gate. He has a gorilla in his house that even he cannot control. The gorilla seems hostile toward Francis. (It is only slightly controlled by a collar connected to a chain.)

The daughter of Miss T and Francis. Wears a pink T-shirt and black pants. She smiles a lot and causes trouble. Has voluminous hair, though smaller than Miss T's. Miss T and Francis do not torture or abuse her. She only gets swatted on the back.
