I wasn't expecting much of this manga at first, but it got really good pretty fast, and it keeps getting better with each chapter, so I can currently say that it is very much underrated.
The characters, specially the main ones, are very deep and interesting, so it's always exciting to get to know more about them, their personalities and their secrets, as the story progresses.
It's a bit ironic how they all feel much more human than the average character from any other high school story, even though they're all animals... but I really mean it, it's very easy to relate to them and
their struggles, one way or another.
The world in this manga is very interesting as well, it has many layers to it and many aspects of it contribute to a feeling of dread, while it addressees the topic of discrimination and "cultural differences" in very interesting (and sometimes gruesome) ways. To put it very, very simply, it's like the dark and gritty version of Zootopia we never got to watch, but with differences that add to its complexity and originality.
My only complaint would have to be the art, or at least it was at first, but I've grown to like it quite a bit so it's not really that much of a problem, it's charming and very distinct, and it doesn't fail to send the message across, specially when it comes to its visual cues, which might be my one of my favorite parts of this manga, they're really well executed and make me feel like they'd be great in anime form because of how dramatic and meaningful they are, and there's plenty of them, since the story keeps jumping from one dramatic scene to another almost constantly, specially during the latest chapters.
My point with that is, do not dismiss this manga right away, because it's definitely worth a read.
