Thrown Into The Life (Supernatural!Narry AU)

Niall and Harry are both students in a university, NYU that is. Niall transferred from Ireland when his girlfriend broke up with him and Harry transferred from Cheshire when his sister got married and moved to New York. The boys become fast friends when they become roommates in the dorms.

One day while visiting his sister with Niall Gemma begins to act weird. Like, serving the goldfish for dinner weird. Then two men burst in and strap down his sister. They strap her down, mumble some satanic crap, and all of a sudden the room’s filled with smoke. Gemma’s left dead. One thing leads to another and the men-Sam and Dean Winchester-explain that she was a demon, and that they hunt things like her.

Harry is determined to learn more about the creatures that roam the earth and how to kill them, so he follows the brothers, learning from them how to kill, lie, cheat, and erase all evidence of his being there. Niall, unable to stop his friend, accompanies him in his quest for revenge. Once he gets it, Niall questions whether or not Harry can stop killing, will he ever go back to his average life or will this BECOME his life?
