In the future, age is not a factor to determine whether someone can perform a certain task or not, but special talent and training. An organization, Machine Robo Rescue (MRR), was established for robots and children to become partners and rescue people from danger. Then 12 children with various abilities were selected and introduced as part of the program: Robo Rescue!
Life as one of the children chosen as part of MRR has started for Oozora Taiyou. Bumpy and hard training is just ahead for the MRR team in order to protect many people's lives!
