I know I need to finish my others but I'm making a blue exorcist reader insert so... Yeah
You have been with Father Fujimoto since the day you were born, like the Okumura twins, he treats you as his own, since nobody knew your original family name it became Fujimoto. The twins still treated you like a sister despite not being related to them in any way. You became the youngest person in history to become an Exorcist at age 7 finishing cram school with two meisters, but wanting to be like Fujimoto going back at age 10 with Yukio to get the other three.
During the fall of the church you were with Yukio preparing for your life in a normal school while Yukio was preparing for his life as a teacher.
Going back you both knew what had happened deep down you knew Yukio was terrified of his twin but he didn't show it, not on the surface.
Blablabla, you become paladin after Fujimoto dies and go to the cramschool to help Yukio with the kids a bit. Finding a love interest that I can't figure out who
WHO DO YOU WANT!?!?!?
