I feel like I've seen enough to actually have a top ten list, although the more I watch the more the list is apt to change.
1. Ayumi Kurihara (Ayumi kind of started it all for me, thanks to SHIMMER.)
3. Io Shirai
4. Mio Shirai
5. Tomoka Nakagawa
6. Hiroyo Matsumoto
9. Chii Tomiya
10. Lin "Bitch" Bairon
And as popular as it is to list the Purple Lightning Sisters as a unit, honestly, I like Io just a little better.
