During a summer camp, 15 children find a grotto by the sea. Deep within it, they discover working computers, some electronic equipment and the owner, a man called Kokopelli. Kokopelli claimed to be a programmer working on a brand new game in which a large robot has to defend Earth against 15 alien invasions. He persuades the children to test the game and sign a contract. Each story of Bokurano : Ours focuses exclusively on one character: the next pilot of the large robot Zearth. It starts with some background information on the character and their underlying motivations while building up to their battle.
