Elliot has been running for most of his life. For the past five years, his daily routine has consisted of scrounging for food, finding places to spend the night and fighting with hostile people. Until... he sees an alluring girl and follows her... to a place he never knew existed. The SPD, a secret organization with the intent of trapping ghosts, welcomes him. But how can Elliot trap ghosts if he can't even escape the ghosts of his past? And is the SPD really what it seems?
