IMPORTANT: This storyline is based off my girlfriend Ellie's idea, so credit for the storyline to her.
So, this is my first fanfiction on here :3 Hope you enjoy!

Levi Ackerman is the best of his kind, virtually undetectable in sound and movement. His attacks were quick, swift, yet fatal to the target in question. His one mistake twelve years previous had driven him to never make a mistake again. Over those years, he earned the name ‘Raven’s Shadow’ through his incredible efforts for the Alliance. When it came to modern day Assassins, he was the one to fear. The mere suggestion that the corporal would hesitate to kill a target was ridiculous, ludicrous to even think. Why would those twenty or so years be put to waste? What could dampen the fire that raged within, when it burnt everything it encountered? For so long, the raven soldier had tricked himself into believing nothing could faze him.
He was wrong.
