So I'm one of those people who read the manga after I finished the first season. I don't remember much from chapter 11, which is about where this second season starts, so I can't really gauge whether they did a good job being faithful to the manga. I can't really go back and read it right now either since I'm typing this right before CCE starts.
I'm gonna edit this later because of that, but I will say: the guy that Hiyori passes in the intro? Screw that guy so much.
