Brody's ghost : the collected edition

After losing his job, his girlfriend, and his home, Brody learns that things can get even worse when he begins seeing a ghostly teenage girl watching him in the street.

What he hopes is a hallucination proves all too real when the ghost tells him she needs his help hunting down a dangerous killer, and that he must undergo training from the spirit of a centuries-old samurai to unlock his hidden ghost talker powers.
