I just downloaded Ahri models which was extracted from League, then I used the tool called "lol2dae" to convert the original model file (.skn) to .dae file so I'm able to importing to Blender.
The model looks fine, I applied its texture (I used PS to convert it from dds to png), and nothing seem to be wrong.
Then I realized that the model has been "mirrored" from the original model. I don't know if I used the word "mirrored" right.. just take a look at my screenshot here for sure.
I also tried extracting some models myself and got the same problem, so I very appreciate any suggestion to make it work right.
