The Girl Of Ketsuki (Naruto Fanfic)

Aoka is a calm girl who, even to her best friend is mysterious. She seems to be weak, being in the middle ranking of her class. But Hinata, who escorted her to the village, doesn't believe she's showing her true strength. But Aoka has a good reason to. Her kekei genkai is the most dangerous, and, if awakened, could take an army. But when Aoka was banished by her father to the Leaf Village, he told her one thing: That village trained your brother, that's why I know it can teach you. Now, with a brother to look for, friends to save in exams, old frienemies coming to kidnap her, and the guilt of her dead relative haunting her, she won't even have time to take a breath.
And all the while, a shadowy figure controlling every fate, and every death is teasing her.
