I rarely ever give 10/10 scores, because there's hardly any out there worth such a score. It tends to cap at a maximum of 9/10 for rare cases. But I just loved this manga extremely much, it instantly clicked with me.
This is actually something I've never seen in a manga, anime or novel before. There's every kind of animal, be it extinct or not, even neanderthals show up! Dinosaurs are teachers and we can even see previous evolutions act as grandparents(it did happen). There's a lot of interesting, relevant trivia that fits in very well with the story. The males are in the original animal forms(but standing upright), while the females are all more akin to beastmen we're all familiar with.
The thing that made this so awesome is that the author isn't just going the usual route of "oh, they're cute animal girls with some very slight animal traits", oh no, they act exactly like the animal versions are supposed to act like, with some differences of course. We also get trivia to understand why they act like this and it makes it even better. All the characters are therefore quite vibrant and lovable. Be it the mc, the different girls in the mc's group or the other characters they interact with, it's all interesting and fresh, after all, we don't see stuff where people act exactly like animals very often.
The comedy is also pretty spot on, it's well-placed and manages to make me laugh or at the very least smile all the way through. This is partly made sure by the fact that it's not really repetitive at all. New, different animals are introduced all the time and the stories rarely if ever repeat themselves. Usually, I'd see a lot of repetitive patterns in a story like this very quickly, but I don't do so here(well, obviously I can see a lot of patterns to how it's written, but not in a way where it negatively impacts the story whatsoever, there's enough new stuff to make sure that the episodic chapters stays fresh).
We have kangaroos with boxing matches, an impala getting together with a lion, a selfish panda learning to be less selfish(and awakening to her masochistic urges), a koala that can't get enough of poop, a sloth that dies easily when exerting herself, well, you get the deal. It's easy to see that the author is doing his research and loves animals.
Recommended to anyone and everyone who likes animals, some good comedy and want to see something new. I guess the girls are cute as well, so that's a bonus too.
