The Central Tanegashima High School Robotics Research Club has long hoped to create the GunPro1, a fully functional huge robot. For years, club members have contributed to its growth, and it is now Akiho Senomiya's ambition to make the ideal of all prior club members a reality. However, things are not as simple as they appear because the club lacks the necessary cash for such a large undertaking. Aside from that, the only other club member, Kaito Yashio, is uninterested in supporting his boyhood buddy and prefers to spend his time playing mecha-fighting games on his "PokeCom."
