Mika Asagi, who helped Beyond the Grave on his last adventure, revives him again. This time, he has to stop Seed, an addictive drug that's turning innocent people into criminals. Also joining the team are Spike Hubie, a genius kid who has lost his memory, Juji Kabane, a dead man with a "Shoot first, ask questions never" personality and Rocketbilly Redcadillac, a ghost attached to a guitar.
