Muv-Luv Alternative 2

With the coup d'état put down, Takeru Shirogane and his fellow cadets are graduated to full surface pilots, ready to take on the alien BETA. But Takeru has a bigger plan in mind: using his timeline-hopping ability to help XO Yuuko Kouzuki complete the 00 Unit and thus implement Alternative IV before it's canceled, as it was in his previous timeline loop.
