1)Yuna
I really enjoy how strong and selfless she is as a person and her devotion to the people. Even when everyone is against her, she still never gives up trying to make the world better for everyone.
2)Kimahri
I like how devoted he is to Yuna and everyone else and how he tries to protect her. He's very sweet and his back story makes him seem like an even more kind and dependable guy. I also enjoy his scenes with standing up to Biran and Yenke.
3)Lulu
I don't like everything about her, but it is nice when she explains things to Tidus and she has some wisdom to her that I can appreciate.
4)Rikku
I like how upbeat and positive she is overall and she also has some wisdom to her whether she sees it or not.
5)Auron
He's alright. I can't think of much I like or dislike about him.
6)Wakka
I enjoy his character development
7)Tidus
Just not my type of dude
