I decided to write this review because this manga doesn't have one and because I'm a fan of Muv Luv series . I hope this will be useful .
First of all I must say that the story in this manga isn't mind blowing but is still good, but as a part of Muv-Luv trilogy this manga is worth reading because it's focusing on characters development and getting the reader more into Muv-Luv universe also this is a must read if you want to play/read ML Alternative .
The story starts with Shirogane Takeru waking up in a parallel world where aliens invaded Earth and the humanity
is on the brink of destruction . Being trapped in this apocalyptic world Shirogane is trying to adapt.
The characters are memorable and they are constantly evolving especially Shirogane from the boy who was brought in an insane world to a man.
The art is very good compared to the prequel and the "plot" is drawn well .
For those who expect mecha battles against aliens and gore fest well I'm glad to say that there aren't any of those things, instead you will get a chance to see a normal high school student trying to become a soldier.
Those who played the VN should try this because the difference is noticeable and it brings few small side-stories.
