Persona MMD--WAIT, WHUT?

MikuMikuDance PV mix with Persona 3 anyone?
XD

What do you guys think?
Since I'm already doing a Kingdom Hearts 2/MMD parody opening.

I've already got the AVI File to work and play in the BG for the MMD program so I can accurately move the characters.
I've got the WAV file to play along accurately to the vid as well.
All I need now is to just set my model characters to move around.

PROBLEM.
There's four of them on the field.
I'm, of course, using Ike, Kaine and Mai. I need one more. And preferably a girl.

This is the video to which I took a part of the play from:

It's a "Battle Against Death - Death Arcane Reaper."
I'm only doing up from 1:55 to 3:00 of this though. I just wanted an All-Out Attack. XD

Character key:
Ike - Minato (Protagonist)
Kaine - Akihiko
Mai - Aegis
???? - Yukari

Anyone want to throw in a suggestion as to which default model of Vocaloid may fit to be Yukari?
The weaponry won't really matter, don't worry.
They're all just basically using their guns to summon their Persona in this. (Not including that All-Out Attack.)

Though if you want to know...
Ike - Katana
Kaine - Naginata
Mai - Chakram (rightfully a halo)
???? - Whatever default weapon I think is best for model

Let me know what you have in mind please!
