In this series, I felt like the only drawback was the story. The main concept was cool and interesting, but they could have shown it off in a whole different way. Example: The series could have started off showing Fear's previous life. And then she could maybe in some way meet Haruaki. That would been a nice start.
Going further, it would have been nice if some romantic was shown.
I really disliked the ending because of the "help" they got, and how the main characters didn't manage to kill the "Final boss" while they had the perfect moment to do so.
Finally, I would have really wished to see more background of Fear and her interaction with Haruaki.
Else than that, everything is nice. You'll get to know the characters background which is kind of interesting and show their skills and personality.
