Tập 1: Kaito và Akiho đối mặt với hạn chót giải đấu robot để cứu câu lạc bộ

Kaito Yashio and his friend Akiho Senomiya are the remaining members of their school's Robotics Club. After Akiho hands in a budget request to the staff room, both she and Kaito, who spends his time playing games on his Poke-Com device, visit an old hangar containing a large robot the Robotics Club has been working on since its foundation, GunBuild-1, based on a popular robot anime, "Gunvarrel", whose final episode was never aired. The next day, the vice-principal agrees to give the Robotics Club their proposed budget on the condition that they win a robot tournament taking place in two weeks' time, with the club to be disbanded should they lose. As Kaito and Akiho contemplate if they can pull off such a feat, a mysterious girl is seen making a report. (Source: Wikipedia)
