Masamitsu Seki is one of the officers who befriended the children and assumed one of the empty places in Zearth's group. He joined the military thanks to his fascination with Idol Defense Force Hummingbird.    ~!During Kanji's battle, Seki sacrifices himself in order for Kanji to defeat the enemy robot, creating another empty seat in the group.  In the anime, Seki threatened Koemushi with a gun and gets his right arm cut off by him, when he teleported his whole body, except for the hand which was holding the weapon to another place. By the time he signed the contract along Tanaka, it was already replaced with a mechanical prosthetic, which hides some sensors planted by Kanji's mother in order to gain access to information regarding Zearth's technology.   In the end, he becomes the only contracted pilot to survive the battles.!~

During a summer camp, 15 children, 8 males and 7 females, find a grotto by the sea. Deep within they discover working computers and some electronic equipment, and later 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 the Earth against alien invasions. He persuades the children to test the game and sign a contract. All but one of them signs, barely a moment later they mysteriously awaken on the shore believing what happened was just a dream.

One summer, fifteen kids innocently wander into a nearby seaside cave. There they meet a strange man who invites them to play an exciting new video game. This game, he explains, pits a lone giant robot against a horde of alien invaders. To play the game all they have to do is sign a simple contract. The game stops being fun when the kids find out the true purpose of their pact.
