Captain Earth aka Kyaputen Asu is a Japanese mecha anime television series produced by Bones. Manatsu Daichi, a second-year in high school, sees a weird round rainbow floating in the sky above Tanegashima and ventures there alone. Daiji arrives on the island while the alarm of a building labeled Earth Engine is going off. Someone asks him if he is a captain, just as robotic intruders from Uranus called Kill-T-Gang arrive. The battle around the shining stars is about to begin.
