Sound of the Sky is a manga based on an anime of the same name, and it runs into every problem that anime-to-manga adaptations do. In a vacuum, this manga is fine. It tells a good story about love and war and music that I think is extremely valuable. However, being only 16 chapters (yes, 16; I do not know why it says 19) it tends to breeze through parts of the story it would have been better to slow down and focus on. This is particularly egregious when you compare it to the much better pacing of the original anime that actually does lend timeto these important moments.

The artwork is fine, but it can feel somewhat stiff at times—not to mention the out-of-place fanservice (which the original didn't have). And while it is a story about music, it does not have any music you can hear, which isn't necessarily a bad thing, but it leaves out the key piece of information that the story's leitmotif is supposed to be Amazing Grace—as no one ever names it—and I would say that's rather important for a story about the trauma, guilt, and redemption of soldiers.

It's still Sound of the Sky, so it's still an extremely beautiful and important story, so I'll give it a 7/10. If you don't like watching anime, I would recommend this manga. But if you do, then you really have no reason to read this.
