Wicked Thief

I was born with an unseen ability, I could steal Kekkei Genkai. I didn't have to replace my eyes or anything just decide that I wanted them. What I mean by stole was that I could give them back, or I could just copy them, and I could collect them. My ability was undiscovered until I was twelve years old. I had witnessed my family get killed, right in front of me. The man that killed them was from the Shigaisen clan. I had felt different after looking at him and discovered I had the Hikarigan, that mans Kekkai Genkai I had stole it from him. I left my home and roamed around aimlessly, I ended up at the gates of Konoha. Where I collapsed and was taken to the Hokage, and when I woke up my denied past became my dangerous reality.
