Main protagonist of Final Fantasy XIII

A.K.I. initially presents herself as a calm and somewhat gleeful individual, with knowledge of Chinese medicine. However, hidden behind this facade is a sadistic and psychopathic woman. A.K.I. has also mastered the use of poisons, displaying knowledge of their side effects, and seems to enjoy teasing her victims. A.K.I. views her fighting technique as a form of "art" and is more than eager to display her "perfect" mastery on others, willingly or not.
