Freezing Vol 23

About Freezing

Beings from another dimension, called "Nova" have started a war with Earth. In response, "Genetics Academy" trains female warriors called "Pandora", who can create special weapons and armours to fight against the Nova. Kazuya Aoi enrols, due to a promise he made with his sister, a famous Pandora who died in battle, and meets Bridgette L. Satellizer, infamous for her solitary demanour, and becomes her "tuner", an assistant who nullifies Novas' psychic attacks.
