Paine is a playable character in Final Fantasy X-2, and the most reserved of the girls. Her past is a mystery and it is up to the player to discover what happened to her two years ago during the events of Final Fantasy X.
Paine is cynical, moody, and reveals information only when she needs to. She is quiet and keeps to herself. Despite being a year younger than Yuna and a year older than Rikku, Paine acts the most mature of the three. Paine is tough and loves a good fight, but she is sensible enough to smell trouble a mile away. If she feels her fellow Gullwings are getting overenthusiastic, she uses sarcastic cracks to jolt them to their senses, and despite Rikku's constant prying, she refuses to divulge information about herself, except for always wanting to fly on an airship and hunt for spheres containing records of Spira's past.
In spite of her dry wit and demeanor, Paine values her friendship with Yuna and Rikku, but it is only after spending three months traveling around Spira by herself that she is able to express these feelings. Her physical mannerisms are boyish, perhaps a side effect from her past adventures with Nooj, Gippal, and Baralai.
