I recently caught up to this manga. I'm glad somebody is translating this despite the seemingly low popularity.
The story currently definitely has many mysteries plotted in it, and that's what makes it intriguing. If you're a theorist, you would surely enjoy this manga. Mostly I'm curious why the white hoods are so ruthless and inhuman, to me it seems almost as if they were hypnotized (check on Rekka's behaviour).
It was also pleasing to find out that the Joker character is neutral and also very strong fighter. Although trusting him may prove wrong in the end, I liked that he balanced out the odds between Shinra's squad and the organisation.
Because let's face it, other than Squad 8, nobody in the firefighters is doing anything against this evil organisation. When I found out that the leader of Squad 3 was corrupted that made me very sad and made me think there are way more corrupted firefighters like this. I hope not. I want to see ewhat other firefighter squads are capable of.
So that's it so far I enjoy this manga, because it's not dull and not everything is predictable in it. Also have to give kudos to the artist's style, his measure of detail is really exceptional.
P.s. Did anyone notice that he draws Hibana wayy to much? She appears nearly in every 2-3 new chapters, even though she was supposed to be just a low class villain then converted to ally. I just thought this indicates that this autor must've grown to like her character more than he planned at the beginning.
