Final Fantasy X-2
Voice Actor: N/A
Following the defeat of Sin, Yaibal decides to join the Youth League. He believes that they are the group which can lead Spira forward, and he personally tries to recruit Yuna to join their cause. This happens shortly before the start of Final Fantasy X-2, but unfortunately for Yaibal, Yuna turns him down.
He later appears when the Gullwings venture to the Mushroom Rock - the headquarters of the Youth League. He gives them some useful information about the Youth League, and mentions his prior meeting with Yuna.
Depending on the decisions that Yuna has made throughout the game, Yaibal may also appear as a hostile person in Chapter 5, and must be fought in order to progress.
