17-year-old human summoner Yuna is the daughter of Spira's infamous High Summoner Braska, the man responsible for bringing a brief end to the destruction of Sin; The Calm. She has decided to follow in her father's footsteps to become a summoner herself. Yuna is expected to travel to temples across Spira to acquire all of the magical entities known as "aeons" and eventually summon the Final Aeon in a battle that will claim both its life and her own.
We can't see the cosplayer's face in this photo, which is a shame, really. It's still a great photo! Nice work!
