Nazi Germany – 1944: As American bombers soar in direction of Berlin, a revolting Satanic ceremony takes place beneath – Hitler and his minions are utilizing the monstrous Nazi Loss of life Rape Machine to render the dimensional boundaries separating the Human World from the World of Man-Beasts and the World of Monster Demons. Dr. Munhihausen Sr.’s life work is about to return to fruition – the conjuring of the Overfiend!
Lower to modern-day Tokyo – Munhihausen Jr. searches for a monster with energy sufficient to beat the all-powerful Overfiend. Since legend says that he who kills the Overfiend will rule all three worlds eternally, Munhihausen is decided to slay the Overfiend and assume full management over all three dimensions. His efforts appear fruitless – till Nagumo’s cousin Takeaki, infused with Nagumo’s blood after an accident, begins to develop monstrous powers.
As Man-Beast Amano Jyaku and his sister Megumi, along with devoted confederate Kuroko try to thwart Munhihausen’s evil plan, nothing appears more likely to stop Munhihausen, descendant of a race of brutal tyrants, from enslaving the world underneath his despicable rule!
