When Obito Has a Sister

I, Uchiha Mimito, a cute little Uchiha girl I have an older brother named Uchiha Obito. He is the best older brother in the world (no objection accepted). He is only two years older than me. I also have a grandma who brought us up, because when we were very young, our parents... Forget it, I won't talk to you anymore, my brother is looking for me! Concept: My OC story
