Kelly Mendes possesses a cold and completely uncaring demeanour.

Through careful study and dedication to isolated martial-combat, Kelly Mendes has turned the act of dueling into an art form. A keen eye and attention to detail allows her the ability to learn their opponent's idiosyncrasies while fighting. Kelly Mendes then uses her own skills to capitalize on the opponent's weakness. Because of this calculated approach to isolated duels, Kelly Mendes has a harder time taking on multiple opponents at once at higher skill levels.
