Leo x Halfa! reader

Okay Halfa as in half of a ghost and half of a human! But onto the description...
Description: You were walking alone in an alley when... *BANG* you heard some type of weapon firing. The first thought that went through your mind was 'RUN!' But as you tried you accidentally somehow get to who was shooting it. It was this weird man in a suit with sunglasses on, what he said made everything in your eyes go in slow motion "Kraang has been figured out, shoot the unknown human known as a tresspaser!" He instantly shot you but then the turtles jump in making one of the Kraang bots drop a canister of mutagen, it slowly went it's way towards you. As you were going up towards Heaven, you got forcefully pulled back and felt powerful, you open your eyes and see the alley you were in but walked it off...
Imma stop there because this looks sooooo long, read to find out! (Also no duh it's mature! A Kraang tried to kill you!)
