Fairly solid, short and sweet action manga.

I don't have much to say about what's good about this manga. It executes its time loop premise very well. The drama, action, and character moments are all there. The most notable strong point would probably be Takeshi Obata's outstanding art, especially when the manga shifts into more intense scenes with glorious detail in shading (although the character designs are way too similar to Bakuman).

So anyone looking for a quick, satisfying read that does almost everything right should try reading this.

Otherwise, while the execution is top-notch, the manga's concept is kind of weak. It suffers a little from the problem that a lot of time loop stories have, which is being ... repetitive. Seeing the same character repeat the same scenarios again and again can be tiresome, and this manga only barely avoids that problem by being short, not because it manages to somehow make those loops feel more meaningful or interesting.

The character moments in the manga are good, but it feels like there's a lot of missed opportunities in characterizing some of the overlooked characters a little more, or in showing MC develop from other characters. Some of that is implied, but it's not enough to give weight to the action scenes. The MC's pain is weighted, but the pain of the other characters' feels glossed over a bit.

Outside of the scenario, we barely know the MC's history, likes/dislikes, etc. His development as a character is, for the most part, standard. It's only later in the manga that he starts to feel a little unique. The length of the manga feels like an issue here, since it does seem difficult to squeeze in meaningful characterization outside of the plot scenario.

The conclusion is satisfying for the plot and characters, but I'm left feeling that there was little to take away from the whole thing. I can't really say that there's some noticeable theme or bit of insight, so it's difficult to relate to or feel like everything that just happened really mattered.

This was a good manga for how well it used its concept, but beyond that, it isn't that memorable. Still worth a buy for how short it is, and Obata's art is godly.
