Hold on a second. It isn't as simple as that. Kamiya isn't the only one who created Dante, Shinji Mikami was executive producer in that game and he put in alot to Dante, as well, and Kobayashi did, too. When you talk about the creator you can't just say 'it was that one guy,' and give him all the credit. More than a few people went into Dante's creation, character designer, directors, producers, modelers, animators, and so on.
This is why this isn't just as clean cut as that. He isn't the creation of one man, even as the director, the people who created Dante are more than one, so out of all of them, hell, just out of the three head honchos who made him who'd get to keep him? Kamiya? Why not, he's the director. Why not Mikami? If you've ever played a Mikami game you'll recognice that sass in any of his characters, Vanessa, Leon, Sam, Gene... Well, maybe not Gene, but you definitly feel his hand in Dante's creation. How 'bout Kobayashi? He worked on more DMC titles than the other two including the original and the most finacially succesful (4) of all of them, why can't it go to him?
We are saying Kamiya tight now because we rather see him do DMC than Bayonetta but the reality of it is that there are several people involved in his creation and it isn't as clean cut as all that.
