A re-adaptation of Muv-Luv Alternative: Total Eclipse and sequel to the Total Eclipse manga by Ishigaki Takashi. There is hope that can only be born in the depths of despair, and a future that only hope can create... In 1973, following the ruthless six-year-long Lunar War, the hostile alien species known as the BETA—Beings of Extra Terrestrial origin which are Adversary of the human race—invaded Earth, killing billions and decimating Eurasia. With the nations of Eurasia having fallen to the BETA, their survivors race to develop a new tactical surface fighter at a base in Alaska. Yuuya, an ace pilot with a bad attitude, is reassigned from the US army to the joint US/Japan TSF development project. There, he meets the imperial soldier Yui. They start off as constantly bickering enemies, and he soon meets the mysteriously cold Soviet soldier, Cryska.
