Looking for some help

Hello,

I'm hoping somebody here with a good knowledge of the characters can help me out.

Very recently my buddy found out through his girlfriend's parents that his girlfriend has a character modeled after her. The problem is, the parents don't know much more than that and couldn't tell us which game or what character she is.

I've spent some time looking on the DDR wikia and my buddy has been watching a lot of videos on YouTube to no avail. All we know is that she's a tap dancer in the game.

If anyone could point me in the right direction, we'd like to find out who she is in the game so we can buy it.

Thank you!
