Okay, so there are gonna be like... two different time skips. (Or three... but it kinda depends)
The base will be standard 13 year old Nuriko and how she struggles on being a ninja.
The first timeskip will skip into 3 years. Nuriko and her comrades will be 16. This is where Nuriko's demon starts to really get active, and tries to claim Nuriko's body as her new one, for the old, that she had lost.
Then, I will throw in a couple of recaps of stories. Including Nuriko's past as a little girl.
Mostly where she was all her life untill she came to the Leaf at age 13.
The second one will be simply the past of Vira ((Zaruu)).
ANd... most importantly... I'm writing to nobody. -_-
Here are some words I picked up to use for my title:
***If I use this one, I will call it "The Sacrifice" since Nuriko is basically just a pawn for Vira.
