Blame the one who make this anime fast paced, the story itself is good, animation, music, voice acting. I don't know, maybe because the money problem they screwed up this. Maybe by reading light novel you can know better what's going on with the story. Pros : - Good Voice Acting (but the anime scerewed this up by making it extremely fast dialogue) - Good Music - Good Mystery- Art quality is consistent

Cons :
- Extremely fast paced dialogue and story
- Oversized Ryouka's bust (idk my friend dropped the anime for this reason)

Once again, the one who i can blame of is the one who make this anime extremely fast paced.
It won't work like Saiki Kusuo did and screwed it all.
