Actually she's a cutom Original character from a chinese Mugen Fan game project. Kof Wing - Kof Zillion.
Just like Cao Long and Sima Li. (see picture...)
This chinese woman is really created with chinese audience "taste" (very long skinny legs, baby feet... ^^

To me, Sima Li (in blue) is their only fitting to KOF design in term of pure spriting work (proportions, color work etc.)
Lu Mei have a good base, but... And Cao Long could have been great but they messed up on some stufs in term of proportions, animations etc.
