Uchiha

Satchi Uchiha is the kind of secret that wanted to be buried so deep that it should have been forgotten. The new world is under siege by the Otsutsuki who is terrorizing shinobi by stealing their Chakra with no regard for life.
Sasuke Uchiha had placed Satchi in a home he thought would hide her and give her a happy life. Satchi grew up and loves her new family with very little memories of who her real parents were. The death of her adoptive family awakens the first stage of the Sharingan.
As the truth starts to make itself known, Satchi questions her entire existence. A boy named Kon claims to be her older brother and wants her to join him. He promises to give her a better home, to teach her about who she is, and who her birth mother was.
What was supposed to be a simple covert mission turns into Satchi's worst nightmare. The answers she wanted, turn against her. The brother she's supposed to love unconditionally poses a threat to her, those she loves, and the rest of the world and the only way to secure the future is to eliminate him.
