Sociopathic Killer [Ereri/Riren Fanfic] [COMPLETED]

" Levi, don't do this... please!"

" Sorry, but your cries for mercy only stir me up even more."

Levi Ackerman is a sociopath and a murderer, when he strikes his kinfe or takes his shot at his victims, he finds a strange sense of joy and excitement. Of course, he wishes that when he killed someone they'd come back to life so he could do it again and again. Even though he hasn't been able to feel the emotions other people felt for as long as he could remember, that changed when the fiftith victim manages to escape him and lives to tell his tale. Now with the police after him, Levi decides to find Eren Jaeger and take him down the road to Hell.

When Eren had escaped the psychaotic murderer, he couldn't stop thinking about him. It was as if there was something more to the killer than what met the eye. Soon enough he starts drawing a murderer in black clothing on his papers at school and eventually is sent to the mental hospital his father worked at.

What will happen to the teenager who escaped and what will the teenaged killer do when he gets his hands on Eren yet again? Will it be like the first encounter or will it be the day when Eren takes his final breath?
