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. 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. While wandering the house, one can find 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 peaceful for the most part if she is removed. Even if Guest steps inside the front gate quietly while her back is turned, she notices like a ghost. If a ladder is placed in her path, she might trip or stumble while running; if she steps on a trap, she groans while holding her foot for a few seconds before returning. Both items are for stalling time. If a ladder is placed in the house, it vibrates, and if you climb to the very top, Miss T will walk in place upon arrival, 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 while she is stopped at the front gate, she will just stare silently with a distorted face. Guest's house is right in front of Miss T's house. There is a plan to invade, but the front gate prevents it. 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 that sells items. It sells strange things like traps, alcohol, gelatin, crowbars, gas 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 items are placed all over her house, she doesn't notice. (Note: Miss T and Francis do not move while the shop menu is open.) There are edible items like honeycombs and cakes, but she doesn't eat them. Bees from the honeycomb attack Miss T, and they sting if touched without gloves. When a video of Miss T teaching appears on TV, she claps and enjoys it. Guest can vault through windows, but Miss T cannot at all. There seems to be a barrier at the pool; Miss T cannot enter and just runs in place right in front of it. In reality, she cannot open the front gate. She won't notice Guest unless they are within about 7 meters.

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