It is a nice and sweet anime. The storylines remind of Ocean's 11 etc. The same kind of good guys that con a bad guy. Pretty basic and somewhat predictable stuff but absolutely fun to watch.
What makes this anime special is de graphics style, that are uncommon for a japanese anime and reminded me of the artistic graphical novels from Cyril Pedrosa. It has a freshness in it that really fits the stories. That alone makes it worthwhile to watch
