I would read this more for aesthetics and art. The stories pretty bad as a mystery and the time travel isn't played with to an interesting degree like Haruhi's endless eights or Utsuro no Hako to Zero no Maria (I think that's the one I'm thinking of). Besides that, the only interesting characters were the main girl, main boy, the blonde/white hair kid, and the killer (as a boy). Besides that, the other characters are pretty throw away. Maybe it's just my guilty pleasure but I could help but personally loved it.

I have nothing to say but MAL wants more soooooooooooooo I'mmmmmm juuuuuuuuust puuuuting bullllllllllll.
