Y/n lives in a small village, the tazekea village. It was a rather small and unpopular village. It was joyful, until one day it gets attacked by a group of demons. You weren't there when it happened, you where in the forest looking for mushrooms since your mother had asked you to. When you came back you saw everything. After that, you run away into the hills, and for years you train with a boy you met in the hills, his name was Inosuke. You grow up with each other and you take the exams together. You meet a very kindhearted boy and everything changes.
