Fukujuu Toshi Megalomania

In a dystopian future where humanity teeters on the brink of extinction, survivors dwell in an underground shelter-city governed by a colossal supercomputer known as the Oracle Machine. This entity has the power to transform human bodies into beast-like creatures, enforcing its will upon the populace.

A mother and daughter attempt to enter the city from the ravaged surface, only to be attacked by nanomachines that alter their bodies into aphrodisiac and obscene forms. Meanwhile, a well-meaning father unleashes his forbidden animal lust on his daughter's clone, and a brother and sister become unwitting test subjects for genetic modification, turning them into monstrous beings. As the Oracle Machine tightens its grip, the boundaries between humanity and machinery blur, leading to a collision of primal desires and technological domination.
