Lord Braska

Braska is Yuna's father, and became a High Summoner by defeating Sin ten years before the events of Final Fantasy X. Braska decided to become a summoner after his wife died due to a Sin attack. His guardians were Auron and Jecht.

He left a video sphere for Yuna on the slopes of Mount Gagazet, letting her know that whatever path she chose for her life, he would be proud.
