Showcase of Kasumi α in Dead or Alive Dimensions. As noted in the Chronicle Mode commentary, Her Moveset is Kasumi's from Dead or Alive 2 (probably for the sake of differentiating between the two)
I also did a Run with her Japanese VA as well. As I probably also mentioned in Chapter 2 of Chronicle Mode, Kasumi α's Japanese VA is Sakura Tange who was the VA for Kasumi from the first 2 DoA games and I wanted to show that off a little more.
Unlock: Complete Tag Challenge Mission 16. Can apparently also be unlocked by reaching the Alpha-152 fight in Arcade Mode Course 6.
