I really wanted to love this Anime. It had likable Characters, the setting was pretty cool, I enjoyed the overall conflict humanoids had with humans and the Art-Style and Animation are straight up beautiful, but it's story is rather disappointing and leaves a lot of questions unanswered or even untouched. For the most part you kinda forget that there even is a Main-Story and that's ironically exactly when the anime has it's strongest moments, dealing with various topics and conflicts a world divided as this could have.
Don't get me wrong, there are some really fun twists and backstory revelations but the Events of the last two episodes make them appear less interesting in retrospect and also feel like they have been added last minute as if the writers themselfes forgot they had a main story to work on.
If I tried to be extra picky I would say that most characters are a little bit naive and easy to convince sometimes (definitely not all but If you have seen the show you know who I mean) ...my least favorite character however was the shows villain whose backstory was just a little bit too far fetched and cheesy for my taste (Not gonna reveal who it is though).
Overall I can't say I didn't have a good time with the series. It's fun and gorgeous to look at, I just see a lot of unused potential maybe a second season could catch up on.
