History
Yuna is the daughter of the family that established Ryuto Girls' Academy. As a friend of Amatsu Marei's, she came to fetch her from Yurigaoka, but when the two took part in the Neunwelt Tactic Technical Conference, they were swept up in the Odaiba Counteroffensive. Yuna fought as part of the Second Division.

During the final battle, when they took down the nestless Ultra by overpowering it with a Neunwelt done by well over nine Lilies, Yuna's power of Charisma made a major contribution.

This made her famous enough that Yurigaoka put her on their list of Lilies to poach during the coming year, but back in Niigata, her reputation is more mixed. This is because she wasn't in top form during the assault by Fafnir, one of the world's Seven Great Ultras, and it was able to successfully build a Nest.
