Double KO

[The only reason Yuna was able to react quickly enough to keep up with this sort of combat in the Magic World was because she was under the effects of Ako's doping. She's a pretty good marksman, and her reflexes are nothing to sneeze at, but unfortunately her inexperience is her biggest weak point.

Those shots on the way down were intended to buy some time to recover - time she never got before Wilhelm's last strike hit her. It wasn't enough to snap her neck instantly, but there was indeed a sickening cracking sound. Yuna's body goes limp as her clothing and artifact transform back, and all she's able to vocalize are pained whimpering noises as she slowly and painfully expires on the streets of Mayfield.]
