Fatum Scriptum

The system that was ruling the ninja world was supposed to be fair. Or so she thought. Who supported, worked, lived in this ruling system was living in the right path. However, those who denied this system, those who left their villages to live on their own, those were traitors, and the path they took would only lead to perdition.
Reality is far more complex, and she would learn it at her expenses. It took few minutes for the world to crumble under her feet, and for her to do what she never thought she would. It all began with that meeting. The day she met the legendary "monster" of the village of Takigakure.

A story about Fuu of Takigakure and Kakuzu, how their pasts are actually intermingled, and what impact it will have on the shinobi world.
It starts with Fuu meeting Kakuzu the first time after the chunin exam we see in the anime(cf. Naruto Shippuden Episode 413).
