Freezing

In a near-future world where Earth is under attack by extraterrestrial beings known as the Nova, a young Japanese man named Kazuya Aoi joins a specialized school that trains genetically altered female warriors called Pandoras. These Pandoras fight the invaders alongside male partners known as Limiters, who possess the ability to restrict enemies' movement through a power called "freezing." At the school, Kazuya meets Satellizer el Bridget, a gifted Pandora who is considered the strongest in her class but has not selected a Limiter. Despite advice from others, Kazuya chooses to become her partner.
