It's a shonen manga with an action/RPG mix and a western-themed world set in the Middle Ages. The protagonist relationship between Criman and Ragna reminds me of Vanitas and Noe, who like to bicker back and forth. The artwork is amazing and Crimson is drawn in a very sexy way. which is comparable to Vanitas. Overall, I quite like the story but it's a shame that Leonika, the best girl in the series, doesn't get much of a role , although the story is similar to a typical shonen manga where the protagonist searches for strength, But I think the fun lies more inthe interaction dynamic between Crimson and Ragna.
