Sakasama no Patema

In a world of endless tunnels beneath the surface, people live in enclosed, dimly lit spaces, wearing protective clothing and maintaining a peaceful existence. A young girl from a subterranean village is drawn to a restricted area known as the "danger zone," despite repeated warnings and reprimands. The reason for its prohibition remains unexplained. During one of her secret visits, she encounters an unexpected situation that reveals long-buried truths. As these revelations emerge, the narrative takes a new direction.
