The series has great potential, but isnt quite living up to it.
They did a great job on making the backstory, but rushed the second half of the story insanely. They should have used twice as many eps to make this part. This would have allowed them to develop the characters a bit more and generally provide a little bit more flesh to the story.
The art is generally good, but the ground in eps 11 for example was weak.
The characters are likelable, but here and there somewhat underdevelopped. As much as a I like this anime, which I very much do, the enjoyment gets killed by the pacing and way of 'filming'. E.g. adding a bunch of stills to do a 5min story in 15 seconds.
Furiously hoping we get a better paced and more high quality second season and hopefully a third and fourth thereafter.
