Karakuri Circus - Sucked me in. I didn't give it a high score since there were some things I didn't like about it, but I felt like it was one series that contained a good amount of character development. Everyone had a backstory. Everyone found some kind of ending. The length of this series should tell someone that this is what it is.
Unfortunately, it's not finished in translation mode. ^_^ (But I saw the raws and I'm mostly satisfied.)
