I'm assuming that I can still post here since other people posted on this topic months after the last post.
Anyway, I watched this anime a year ago. I thought it wasn't bad, but man... some many characters died. It really felt hard to get attached to anyone but the main character since the other characters would either die or just leave the cast when I can guarantee that most anime like this would have them become main supporting characters.
It was just... frustrating. Still, I thought it was good enough to pass the time (when I had time, that is).
