They Will Never Suspect It

In this story, you are an assassin of 14 years of age. You got separated from your family by the HeadMaster and had your own house in Elmore. You had many targets in the city and had to take them all out before you got to chose to stay or leave. Something special about you is you sang songs while you beat targets. Only after the song ended is when you would finally kill them. Normally blood would be everywhere and the target would be soaked in their own blood. No one knew what you did for a living.
