The main issue with this anime is how good it is, how great the characters are and how insanely good the plot it is. And 13 episodes is not enough!!! Clearly. The anime is good, but you can tell some scenes should be longer or the transition to a moment/place to another needed more time to flesh out. At the same time, we spend too much time in moments where we needed to spend less time and other moments need like 3 episodes to actually enjoy it. The romances is barely there but the moments between them are gold, the dynamics between the characters isreally interesting because everyone has both good and bad elements, and the violence is so realistic. I really liked the settings, we have a more diverse Japan, with elements mainly from Middle East rather a hard Japanese style.

HOWEVER, works great as a "trailer" to the manga so we can follow the story.
