Okay to clear things up about what this book is about (because let's be honest, some ppl are lazy to read the description)

Reader: 20 years old, left Konoha 12 years ago, lived in the wilderness all that time, came back to take care of Naruto as a promise, super strong but can't control her powers

Naruto, Sasuke, Sakura: 12 and you know the story

Kakashi: 28 and you know the story

I hope that clears up the description? Ask question if needed. Enjoy!
