The Robotics Research Club at Central Tanegashima High School has been striving to bring the impressive and fully operational colossal robot, GunPro1, to life, to honor the dedication of past members. Despite their leader, Akiho Senomiya, being resolute in achieving this objective, a scarcity of resources poses a challenge to their progress. Kaito Yashio, the club's only other participant, is unenthusiastic about lending his assistance, as he commonly plays mecha-fighting games on his PokeCom, wasting his time. However, Kaito's uneventful life is interrupted by an enigmatic message with a voice drowned out by the noise. Eventually, he traces the message's origin to Airi Yukifune, an AI exclusive to the augmented reality system within his PokeCom. While in the midst of Robotic;Notes, Kaito discovers a dangerous file in Airi's database that could potentially result in dire consequences in the future.
