Im torn between giving it a 10 or a 9, what captivated me the most, and what made me start reading Levius is the art style, but it is not only a beautiful work visually, the characters gain great depth in the short run it has, and the world is incredibly interesting, its got brutal and stoic art, while also balancing out with beauty. In the beginning the narrative reminds me a lot of Blame! it relies a lot more on its art, and visual story telling rather than in dialogue, but as the work progresses we learn more about the characters, their personalities, andtheir goals.
As a conclusion Im just gonna say that if you either like beautiful art, or great fights, you should give this manga a try, it wont disappoint.
