Satomi is aimlessly attending a vocational school and becomes a member of the robot club by chance. There are two robot clubs at her school. The first club's members are handpicked elite and have regularly participated in the robot contest. The other one, which Satomi belongs to, is full of hacks and the club is about to close down. The second club participates in a local contest, but can't even pass the first stage. However, their unique idea is praised and they are invited to attend the National Robot Contest. Satomi, who hates losing, burns with passion for the contest in order not to be disgraced in public.
