Lose Your Dnim

The title for Teen Wolf: Season 3b. It sums up what happened to one of the main characters: Stiles Stilinski. He becomes possessed by an evil Japanese spirit known as the Nogitsune, or Void Kitsune, and goes insane- becoming trapped in his own mind. His body, under the control of the Nogitsune, goes on a homicidal rampage with the Oni, (ancient shadow samurai), feeding on pain and destruction- of which the Nogitsune gets pleasure from.
