In a futuristic world where Earth has been invaded and is at war with aliens from another dimension called the Nova, a boy named Aoi Kazuya enrols for training at a special school for genetically modified girls called Pandoras, who battle the aliens, and their male partners, called Limiters, who use a special power called freezing to limit their opponent's mobility. The protagonist makes the acquaintance of an unusual older girl named Satellizer el Bridget who appears to be the most powerful Pandora in her class, but has not yet chosen a male partner to be her Limiter, and in spite of the warnings of all his friends, he decides to be her Limiter.
