From the famed Japanese studio that brought you Gappa: The Triphibian Monster and co-produced by Fever Dreams, the producers of The Machine Girl and Tokyo Gore Police! In Japanese folklore, kappa are water goblins closely associated with a certain rural village in Japan. Unfortunately, the area is also home to a militant group of scientific researchers dedicated to developing amphibious super troops based on the legendary kappa of old folktales. When their weird experiments go awry, things get crazy with the appearance of a living kappa and the detonation of an atomic bomb! The consequences are of epic and deadly proportions as a giant monster arrives in the midst of the nuclear fallout and Japan’s defenses are once again helpless. Mankind’s only savior is an ugly irradiated water goblin with vengeance on its mind. Surprisingly, this is only Nikkatsu Studio s second foray into the ever popular Kaiju genre.
