I think her name is suppose to be Eir, at least Eir is a goddess based on Norse mythology. Air seems a little weird, but maybe I'm wrong.
Anyways,
You need to max break limit the SSR and use need 3 draconic eyes, completed eyes, not shards. You can supposedly get more from exchange shop using cores from Advent Ragnarok in the future, instead of having to get 1 shard a week from weekly. Not 100% sure.
Though it resets their level and you have to level and break limit her over again in her awakened form with even more costly break limit requirements.
