Yuna (Dissidia Final Fantasy Opera Omnia)

From Dissidia Wiki

A quiet, yet determined summoner who guides the spirits of the dead to the Farplane. On her pilgrimage to defeat Sin, she encounters Tidus, a young man from another world whom she welcomes as her new guardian. Though at times it seems as though they are on a hopeless journey of doubt and loss, they at least have each other.
