Unfortunately it is a male ghost, but I didn't have the heart to tell him. Emi's Father - Loony fellow that has great power over the netherworld. Bunbei - Erotomaniac spirit and the ringleader of this existential orgy.

And so the paranormal research club is tasked with discovering if the suicides are being caused by malevolent spirits.
