Captain Earth

Trama

Second-year high school student Daichi Manatsu travels to Tanegashima after seeing a peculiar round rainbow in the sky, an image that stirs memories of his father's death and a past encounter with a mysterious boy and girl. Upon his arrival, an alarm sounds from a building called "Earth Engine." Robotic invaders from Uranus, known as "Kiltgang," appear, and Daichi is questioned about being a captain, signaling the start of a battle.
