I don't think she's supposed to be a 'gangster'...she looks more like a fighter/boxer. :shrug
Anyhow, from what I saw of it so far, I like it. And I agree with Lora-Ayu, ayu does dominate the PV in the short ver. Maybe they thought doing that would get more ayu fans to watch, and therefore buy the single? That's what I am thinking. I can't wait to see the full PV. Naoya is hawt, and ayu is dancing! xD
