I love Mai since Fatal Fury 2 so I'm a hardcore fan of her. And I love DOA since DOA2 (I remember I used to play Kasumi because she looked like Mai) but I never had an Xbox so when DOA became exclusive for Microsoft, I lost my contact with game series. I couldn't be happier when I saw DOA5 announced for both PS and Xbox. And now that Mai is coming to DOA5... well, is just a dream to me. The sad thing about this is that she won't come back in future DOAs
Anyway. Let's talk a bit about her attacks
I guess she will have, at least, her 4 most typical and traditional special moves.
-KachouSen: a throwing fan. I guess it will work like any other projectile in this game (Raidou's, Nyotengu's) but smaller and faster. Not sure if it will be used for combos or strings.
-Ryuuenbu: tail's flame. I think this attack could work similar to Rachel's qcb+P, for instance. Even the input is the same.
-Hisatsu Shinobi Bachi: elbow launch. It will work like any other launch attack in this game (like Ayane's flying kick or Jan Lee's flying kick) and it can work in a string since it has a first hit before she launches herself.
-Musasabi Mai. That's the most tricky one. It is done in air and since in DOA there are no jumps, I guess it will have to work as other aerial attacks. Only after a jumping move and as a finisher of that move. It could be nice if she could do Musasabi Mai with punch or Ukihane (knee drop) with kick.
