Came across a volume at the bookstore and thought the art looked really good. To be honest I am surprised by how low the score is on MAL, given that 20 chapters in it has done well what you want a new story to do: introduce the premise, build the world/setting, introduce the characters in a way that isn't overwhelming, etc. Maybe it's a little generic as some critics say, but in this case it manages to feel fresh. I'm someone who has grown out of the target demographic (shonen), but I still feel like there's something here to keep me invested.
I see this manga as a better and less edgy Tokyo Ghoul (in terms of the opening arcs) that includes elements from Kekkai Sensen and Noragami that I enjoyed. The characters are definitely the strongest element of this story, as not only are their designs unique and memorable, but their personalities and development are coherent. Of course, as of now there aren't enough chapters to judge if the character arcs are "good", but so far the foundation for a solid story is here. The art is really well done and the humor is notable as well. The battles are easy to follow and visualize, which has been an issue for me in other shonen manga. I hope this author continues this work for as long as they are able.
