First Look: Muv-Luv Alternative

Aliens known as BETA have invaded Earth and slowly spread across the planet, destroying all life in their path. Humans have developed mecha called Tactical Surface Fighters (TSF) to combat the threat, but this has only slowed their advance. As the alien wave moves into northern Japan, TSF pilot Sayoko Komaki witnesses the horror of the BETA first hand, powerless to stop them.
