The story is really well written; I really enjoy reading it. The main concept of the manga is having a time loop during a battle that is taking place between the human race and some kind of extraterrestrial race. The main character finds himself trapped in this time loop, and starts looking for a way to change his fate. This manga has very little romance. There are some girls, and interactions between them and the main character on the manga, but this manga is centered more on the fight, and survival, so definetly wouldn't read it if I were looking for romance. The conclusion of the story in the book is quite satisfying since it answered every questions and plot holes that might have appeared. Reader is able to understand how the war started, why the time loop, how the main character got trapped in the time loop, and if there are other people experiencing the same thing.
The characters are well design, and they do not disappoint. The main character starts like the typical afraid and shy guy, but shows growth quite immediately. He becomes quite a badass after a couple chapters, and has some kind of darker side that makes him more interesting as the story progresses. The second most important character, who is a girl, is also quite interesting and well develop character. She starts as a role model, and an invincible soldier, "the full metal bitch," who has killed many enemies despite her small figure. As the story progresses these two become a bit close, and help each other to find a way out of the loop and win the battle.
Art is really good, the characters look really nice and the way they were drawn does live up to the description given to them. The exoskeletons and weapons, they use, look quite fantastic as well. Unfortunately , there is just one thing that is not good, and it is the way the extraterrestrial enemies were drawn. When I read the book, I imagine them a bit more humanoid, but the ones from the manga are just some giant spiky balls with teeth.
Overall this manga is quite a good read, the art is quite good, it sure won't disappoint for those who like war and fighting themed mangas.
