In the future, the army of space monsters invading the solar system has not ended. The boys and girls with superpowers who can summon large robots, the "TOPLESS", formed a space monster attack force to protect the solar system. The girl Nono admired the legendary astronaut Nonolili and hoped to become an astronaut, but she ran away from home and ended up working as a restaurant waitress. By chance, Nono met Lalke, a member of "TOPLESS", and Lalke rejected Nono's request to join. But at this time, space monsters suddenly appeared on the ground. Nono was involved in the battle, and her hidden superpowers were stimulated, and she defeated the space monster like a superman. Nono and Lalke became fighting partners. However, the power of the space monsters and the truth of the world far exceeded their imagination.
