#9: Ghost. ("Mujina")

A "mujina" is a faceless ghost. I often wondered what circumstances would cause such fate, but the mst plausible I think, is that a mujina is a "Jane (or John) Doe"; an annomymous/forgotten victim, a cold case, an unsolved death. No face, no identity, no name, nobody to be mourned by. With so many crimes ending up like this, it's amazing you don't see more ghosts like this.
