The latest trailer for Yakuza 3 (after the break) purportedly introduces the characters in the upcoming PS3 crime drama, but unless you're already familiar with the series, it's going to be a bunch of incomprehensible Japanese names, listed by affiliation with incomprehensibly-named crime families. However, if you take it as a few minutes of badasses glowering (and taking care of children) and slapping dudes, it's pretty entertaining.
If you're in Europe, you can step into Kazuma Kiryu's shoes right now with the demo. With any luck, North America will be able to join you in those increasingly crowded shoes later today.
When you said "taking care of children," I thought you meant taking care of childre - mob style, not babysitting them. What kind of mobster doesn't have a nanny to take care of the kids?
