Seina Yamada is not unlike most teenagers. But Seina suffers from a terrible misfortune. He happens to have the worst luck of anyone on Earth! When he rides his bike, it falls apart. When he hurries downstairs, he ends up in a crumbled heap. However, when a space craft nearly crash lands right on top of him, Seina's luck takes a turn for the better…or does it?
