Those known as "Grenimals" are grotesque creatures who endanger people's lives. In their search for more extreme pleasures, there are the "Lycanthrope," who cause disarray throughout the world, and the "Vampires," who despise humans as livestock and feed on their blood. The curtain opens on the ferocious battle between the Greminals and the executioners who face off against them.
