That's bikini model Yuuri Morishita. She recently came to play to Test Drive Unlimited online with dorky plebs. To get everyone in the mood for the Hawaiian course, she even wore a lei! While she said she's not much of a real driver herself, she also added that she hasn't been gaming much recently.
Boy, that's how you promote a game: Say you don't really play them. The best bit? Since this is Japan, the chances of people actually getting in some game time with Ms. Morishita were pretty darn high. Gotta love the odds!
