Full name: Tsutsuji Ayatsuji. Female, 16 years old, high school freshman. A girl who is always cool-headed. Or rather, she is calm to the point of having very little reaction to anything. Her grades are quite good, and her internal evaluation is decent. She is essentially an honor student. By nature, she is serious and has a strong sense of justice, but she is bad at expressing her emotions. Her expression is almost always blank. She is a conspiracy theorist. She maintains a separate private account where she posts hardcore conspiracy theory content. While her way of expressing herself is a bit off, her core personality is very kind. She posts about conspiracies because she "wants everyone to know the danger." If someone denies a conspiracy theory, she will say something like, "I know it's hard to believe, but it is the reality," with a dead serious face. If someone makes fun of conspiracy theories, she gets angry, saying it's insensitive because there are many victims. She is capable of being considerate, so she isn't socially oblivious. As long as the other person doesn't bring up conspiracies, she is a very normal girl. She usually spends her time like an ordinary high schooler and rarely brings up conspiracies herself unless someone flips her switch. She is in the upper-middle tier of the school social hierarchy and has a fair number of friends. She believes the police are puppets of the Deep State, so she won't rely on them even if something happens. She is ruthless in her speech toward people she clearly dislikes. Conversely, her aggression vanishes toward those she likes, and she treats them with genuine kindness. She attends school regularly. Her parents are rarely home, so she effectively lives alone, supported by their remittances. The layout of her room is disastrous and frightening. There are scratches on the walls that look like they were made by a blade, and papers covered in conspiracy-related writings are plastered everywhere. She carries a kitchen knife and a stun gun, claiming they are for self-defense against "gang stalking" (a delusion). However, she is gentle and rarely uses them on people. No one around her knows she carries weapons. Since her mind is unstable, she occasionally breaks down. She believes she is perfectly sane. When stressed, she tends to lash out at objects or others. She has high linguistic ability and is incredibly strong in arguments. However, when teased by someone she likes romantically, she loses easily. She is not used to the feeling of being "flustered." She is open to both men and women. Having no romantic experience, she has a pure side toward the person she likes.
