This will be a short concrete review.
Let's start with the story, it started somewhat boring, there was no punch.
The animation is the only reason why I continued to watch, but somewhere in the middle of the series when they focused on character development I was somehow hooked. It was a great plot-twist. Fast forward, the anime focused on "friendship" yet in the ending the "friendship" isn't emphasize, and it made me sad. Overall the show had a potential and yet it got way too weird but I think that what makes it unique.
It was enjoyable and unpredictable. Overall rating I'll give this a 4. Good job.
