Bored with her claustrophobic underground world, Princess Patema explores the danger zones where terrifying creatures called Batmen reportedly lurk. One day she discovers a huge shaft that disappears into the darkness above and below. After an encounter there with one of the Batmen, Patema finds herself in a topsy-turvy world unlike anything she has seen before and forced to come to grips with a solitary boy, Age, who has, from her point of view, a very surprising outlook upon things.
The setting of Sakasama no Patema really reminded me of the world in Pale Cocoon. Both settings involve a dystopic future where certain parts of the world are simply off-limits and considered too dangerous to enter. And in both, the protagonists are tempted into exploring the unfamiliar by mysterious pictures of blue sky and green land, drawing new conclusions about their worlds of origin.
Princess Patema lives in an underground world, but one day tumbles headlong into a void and out into the wide open world above the surface. Age is a student on this surface world when he spies Patema hanging upside-down from a tree. He pulls her down to safety, struggling to keep her earthbound. Together they master the art of navigating competeing gravitational forces and set out to discover the secret that keeps their worlds apart.
The beautiful, strange, sci-fi apocalyptic world with a side of young telegenic characters exploring it... well, that could describe either of these works by Yoshiura. If you enjoyed his first feature film Patema Inverted, try Pale Cocoon, the short that made his name - or vice versa!
