Let's start with the fact that you are a hashira already at 15 years old, you are very quiet and calm, you have very good hearing, you get along very well with everyone, and Tengen treats you like his own daughter, and you see a parental figure in him, although he was surprised why you were so calm and quiet. Tengen did not know that you were traumatized, since when you were only 5, a demon killed your parents, your brother managed to hide you after...the demon killed him too... it was daytime now and everyone was doing their own thing, and you decided to just sit outside near the hashira estate (all the hashiras always thought that you were a boy because you always wear pants and you look like a boy, only tengen realized that you were a girl but decided to keep quiet because he wanted to see the reaction of the hashiras when they find out that you are a girl)
