One has to wonder if SNK even owned them, or if they were creations of Sammy / MMV.
Also never sure if that story can be taken as anything more than a semi-dream match... and have they ever appeared in any of the side-games on Cellphones or such?
Just about EVERYONE whose ever been in a KoF gets a chance there.
I wouldn't mind seeing Reiji and his little Chibi-Chizuru daughter making a re-appearance (maybe she and Kogoro could be friend? Awww! LoL), however. Chizuru could use a friend to flesh out her story more, and a male who uses abilities similiar to the Yata mirror could make a pretty interesting semi-replacement to Yashiro's rapid-attack abilities. And maybe even a good rival for Shen...
