Duke Saraie's Healthy Walking Navi: Let's Become Beautiful doesn't teach DS users just how to walk correctly. Oh, no. It teaches them how to walk beautifully and get in shape in the process. Duke Saraie is 50-something former model who has built an empire on teaching Japanese people (women, namely) how to walk. He hails from Western Japan and appears on TV here in Osaka and Tokyo, instructing those in the way of what he calls "Dukeswalk." He is so successful that he actually resides in Monaco. What's more, his DS game is coming out in May. Hey, why not?

Oh. Duke is NOT the guy in the suit. Brian Ashcraft
