If you've read some of my other reviews, you know one concept that interests me is that of immortality. Time looping is another concept I find enthralling. It's almost like being immortal, except you live the same time period over and over again. In some ways, I feel this could be even worse than immortality, since usually the situation that is repeated is an unpleasant one.

Before we dive into the story, I'd like to mention the artwork. It's absolutely top notch. Every panel has a painstaking amount of detail, from the character designs, to the suits, to the environments. Obata Takeshi is responsible for the designs, whom some of you may recognize as the illustrator of Death Note and Bakuman. While I haven't read either of those manga, I can only assume his work is in top form here.

Aside from the time loop aspect, the story isn't that special. I won't spoil anything, but expect a typical sci-fi mecha setting. The time loop is what makes things interesting. The main character slowly learns the rules of the loop, and the reader along with him. If you have a scientific mind, the implications of each rule will leave you fantasizing for at least fifty loops.

An important aspect for a time loop story (especially one where the main character remembers the loop) is how the character(s) adapt. Do they resolve to find a way out? Do they learn to accept it and endure for... well, eternity? Or do they lose their minds? There are so many ways for a character to react. Yet, the one that makes the reader's blood boil the most is when a character strengthens their resolve and soldiers onward (literally).

The main character is many people's definition of "cool", and it works for this setting. Unfortunately, not all characters are created equal. The main character and main heroine get some pretty heavy development, but none of the side characters do. It's understandable considering the nature of the story. Not much can change after all. However, we never even learn much about these characters. They're just faces that pop up every once in awhile. This, for me, was probably the weakest aspect of the manga.

People who don't enjoy gore should avoid this, as the artwork is very... detailed. I'd recommend this for people who like sci-fi or heart pounding action sequences. I enjoyed this manga, and it wasn't that long of a read. If you find yourself with nothing to do, this manga won't leave you asking for your time back (unless you're just selfish, then shame on you).
