Fumoon

In the aftermath of nuclear testing, a remarkable evolution has given rise to the Fumoon, a diminutive yet exceptionally intelligent humanoid species thriving on a secluded island. Dr. Yamadano is among the few who recognize their existence, but his claims are met with skepticism, save for a handful of witnesses, including detective Shinsaku Ban, and young men Rock and Kenichi, alongside Kenichi’s sister, Pichi (Pinoko). As the Fumoon embark on a mission to gather animals from around the globe, they prepare to evacuate Earth, driven by the foreboding knowledge of an impending disaster—a suffocating cloud of black gas generated by a stellar explosion.

Amidst the chaos, Rokoko, one of the Fumoon, forms a bond with Kenichi and takes it upon himself to aid Dr. Yamadano and his allies. Together, they strive to build a spacecraft capable of saving a select few humans from the impending doom. With the help of Dr. Ochanomizu and the enigmatic Dr. Frankenstein, they race against time, navigating the complexities of interspecies friendship and the urgent need for survival.
