Zetman

This was one of the better action animes to come out in a while...

The story revolves around Jin and Kouga, two kids who have a strong sense of justice from a young age, although justice can mean different things to different people...Jin saves someone from a disaster and asks payment for it, whereas Kouga prefers fame to money (since his parents are already extremely wealthy). As they grow up their need to protect people and fight for justice only strengthens, but they both have different paths to walk...eventually they face 'players', crazy monsters who were created by rich men for sport gambling, but have decided they'd rather walk amongst (and eat) humans instead...now Jin and Kouga have some serious enemies of justice...

There wasn't anything exceptionally unique about this show, I just liked the concept and execution. It's quite violent and bloody, so probably not for kids...check it out.
