Shin Choujin Densetsu Urotsukidouji Mataiden - Season 1

In 1944 Nazi Germany, amid an American bombing raid on Berlin, Adolf Hitler and his followers conduct a Satanic ritual. They employ the Nazi Death Rape Machine to weaken the barriers between the Human World, the World of Man-Beasts, and the World of Monster Demons. This act aims to fulfill Dr. Munhihausen Sr.'s goal: summoning the Overfiend. The narrative shifts to present-day Tokyo, where Munhihausen Jr. seeks a monster powerful enough to defeat the omnipotent Overfiend. According to legend, whoever kills the Overfiend will gain eternal dominion over all three worlds. Munhihausen Jr. is resolved to achieve this and seize total control. His search appears unsuccessful until Takeaki, a cousin of Nagumo, gains monstrous abilities after an accident infuses him with Nagumo's blood. Amano Jyaku, a Man-Beast, along with his sister Megumi and their loyal ally Kuroko, strive to counter Munhihausen's scheme. Despite their efforts, the descendant of a lineage of brutal tyrants seems poised to enslave the worlds under his rule.
