Freezing

An alien invasion threatens Earth, with humanity's survival depending on a force composed of genetically modified female soldiers called Pandoras and their male counterparts, Limiters. Kazuya Aoi, a Limiter, attends an elite academy to train as a soldier, driven by a vow to his late Pandora sister. He faces early challenges at the academy, particularly from Satellizer el Bridget, a second-year student who has never lost a combat simulation. Kazuya must rise to meet her and prepare for the larger conflict ahead.
