I have actually thought of this LOL! The name sharing wasn't intentional, but it is now just the smallest nod. For context, I made yūna before i was even aware of any characters of ffx or anything about ffx, a friend mentioned her bc i noticed i wasnt allowed to put yuna as a name in the cc. I did actually try to find a different name i liked with her, but yūna fit so much i just accepted them sharing a name LMAO.

Ough when I watched ffx it was hard to not be an oc guy and think of MY yūna, but i saw a few similarities that would lead me to think Yūna at the same age would get along with her.
These are both girls with the weight of a world on their shoulder, who live in the crater of a legacy left by their famously heroic fathers. They are steeped in a world of grief, after said world was drastically transformed by a major event. They are both held up and rise to become something like their fathers. Yuna had accepted her role a lot more than yūna does despite them both pursuing it, shes more sorrowful about events whereas yūna expresses her own sorrow through anger primarily. I think yūna would actually be softened by yuna, someone who shares in a similar situation but sees what opprotunity she was given in a different light, and have a soft spot for her because of yuna remaining kind despite her lossess and hardships and knowing her end.
And I think yuna, in turn, would see past yūna's hard exterior knowing their similar situations.tldr; yes

To myself ive kinda thought of yūna and her sharing a name as (if she were a canon ffxiv character) as the smallest nod to yuna, even if the similarities in their situations was 100% coincidental LOL. Funnily enough, yūna being a summoner is also a huge part of her lore!
