As she isn't covered by the Rival Schools characters, Kei, is Kei Chitose, who is canonically Sakura's best friend in Street Fighter. Also, she was the character who I half expected to bash some poor schmuck over the head with something that goes BONG as the lone non-fighter character in the group.

I have to say though, the addition of those four really added... something to the chapter, partly just an outsider's view of the situation, but something else that I can really put my finger on. Somehow, I also expect Karin to make an appearance at some point soon in the future, that girl strikes me as someone who hates to be left out of _anything_. (And I bet the interaction between her, Gryphon and MZ would be hilarious.)

I can't wait for the next chapter, whenever it comes out really. With how Chun Li is foreshadowed to likely act and with Cammy and Decapre all in the mix, it's bound to be explosive.

(On a last random note, those two wins that Gryphon is noted to have won at the beginning, were those against Charlie Nash and Blanka?)
