Final Fantasy X-2/Rikku

Yuna's cousin and an Al Bhed. Rikku helped Brother obtain and repair the airship the Gullwings now use. She was one of Yuna's guardians during Yuna's pilgrimage to defeat Sin. Unhappy with the fact that Yuna was ready to sacrifice her life, she helped convince Yuna to defy the teachings. Now that the Eternal Calm has been brought about, she is dedicated to finding excitement for her cousin - even if it gets them into trouble.

During the prologue, Rikku will be your avatar. After Yuna's arrival she becomes a member of your party.
