Other info: Lulu is one of the Yuna's gaurdians beside Wakka and Kimahri. Her relationship with Yuna is a sister-like bond. She'll protect Yuna as a sister and as a gaurdian. Lulu's magic is black. She is not a person you'd use for attacking with weapons. Also, as you can see, Lulu is from Besaid Island, just like Wakka. Lulu and Wakka knew each other very long. And I possibly think that Wakka secretly loves Lulu.. However, Lulu was with Wakka's brother, Chappu. However, Chappu died when he was in the Crusaders. He wanted Lulu to live peacefully without Sin around. But he died at Djose Shore, along with many other Crusaders. I guess that's why Lulu hates Sin.
Her Past: Well, Wakka's and her parents pasted away when there was Sin attacking when those two were young.I've also heard Lulu is a gaurdian to two summoners. Before Yuna, Braska's daughter. The first was Father Zuke, who she was gaurding with Wakka! Anways, Father Zuke cared for Lulu alot. Is it possible that he may have taken cared of her when her parents passed away? Well anyways, the second summoner was Lady Ginnem. She guarded her with Wakka also!! Lulu Lady Ginnem were very close however, Lady Ginnem died..
