I enjoyed reading this one-shot a lot. Even though it was fan-translated, it was still stellar. Yet an amazing one-shot by the Phantom Seer duo, it features amazing world-building and an intriguing setting. If it gets serialized in JUMP, it will surely become one of the best mangas to read. While some say it strongly resembles D-Gray Man, I believe it has its own unique setup as well that doesn't fully imitate D-Gray Man. I prefer to enjoy it for what it is rather than unnecessary comparison to D-Gray Man. Considering the action, story, art, characters, and excellent world-building, I would give it a solid ratingof 8/10. It has a surprisingly nice story concept, and each panel is brimming with artwork that will make you say "wow." I truly appreciate the incredible artistry behind it. Matsura-sensei has created superb character designs that are sure to become very popular if it's serialized for real. Moreover, I don't want to spoil anything. Just go ahead and read it to see for yourself!
