The Uzumaki twins: How could this happen?

We all know the hero, Uzumaki Naruto. But if he had a sister, how would that change the timeline? And what if, she's not like her brother, in a way that people fear?
This story answers that. So come and read. Read the story about Uzumaki Satomi.

'At that exact moment, she promised herself that she would do anything and everything to protect him.'
'Otouto, you are not a monster. And don't you dare run from me. I have him in me too, dattebane. And don't for a second think that I and sensei don't care about you, because we do. Just ignore that moron, okay.'
'Yeah, funny. My brother, who is chasing Sakura, and she's chasing Sasuke and Sasuke who is the most antisocial of all. It is gonna be one hell of an adventure, dattebane. I would almost want to switch teams with you, Kiba.'
'Because, I, somewhat, understand their struggle. I wanna help them like I wanted someone to help me back then. You know how hard I had to fight every day for me and Otouto to survive, and not starve. So, when I see them struggle like this, I wanna help in any way I can.'

I own this cover, I made it, as well as my oc. I don't own Naruto.
Also, there will be mention of suicide, and maybe self-harm, and violence.
Also, I promise the chapters get better the farther you get into the story.
