Story: 6 it’s basically Pokémon meets shin Megami tensei but it’s written as a shounen. I personally find no problem in it other than that it’s a bit cliche and the later half of the story goes a bit off the rails. Also it ends on a cliffhanger ending but at a point where it’s not the worst thing in the world.
Art: 9 The best thing about this manga is the unquie demon designs which go in a monster of the week like order. The end chapter descriptions are always fun to read and have a good full body shot of each creatures design. Plus I enjoy the strange way they emerge from the user. The overall art is also pretty having fun somewhat brutal action scenes with the characters making fine if not a bit of generic facial expressions. Also the Mc main monster has quite a edgy but still badass design.
Character 6: Most of the characters are pretty flat not to the point of being unbearable but don’t expect anything to knew, they all nicely fit into their caricatures fine.
Enjoyment: 7 Honestly it’s pretty enjoyable if you are out of things to read and are looking for a fun, some what darker shouldn’t. Especially if you love manga that present the monster of the week type of story line then you will probably enjoy this manga.
Overal: 7 a solid action manga for sure, it has no particular negatives that really stand out as long as you know what your getting into which is darker pokemon /2000s show that ran that had a collection of monsters.
