Sakasama no Patema

Age is a student on this surface world, a totalitarian society whose compliant population has been brainwashed against the "sinners who fell into the sky." When he spies Patema hanging upside-down from a tree, he pulls her down to safety, struggling with all his might to keep her earthbound as she grips on to him for dear life. Together their weights cancel each other out, and once they master the art of navigating competing gravitational forces, they set out to evade the leaders of Age's world and discover the secret that keeps their worlds apart.
