Iโm pretty sure sheโs from a hunt from a while ago and I honestly donโt remember which one it was. Iโll find it for you if I can.
She's from the prismeyland hunt (idk the exact name) and she was a side story avi so unfortunately you can't get her anymore.
Hunt announcement Legends of Spring More info on how she was collected in the Stories Tiers and Rewards post
Anyway you could only get her from completing a story line drop requirement ๐คท๐ปโโ๏ธ Tho I wouldnโt lose faith in getting that avatar since ATA does have the tendency to release the same avatar but make it slightly different. For example, they did that with the ghost avatars from the Malice in Wonderland Hunt.
It's supposed to take you to the post specifically in the Stories and Rewards Thread. ๐ Maybe the link is bad? Idk ๐ I haven't played with the post links much yet.
When I try to link, if I do any thing other than the first main page link then it messes up or works a couple times then decides to not :< (luckily though there's a new search thing where you can search within a specific thread and it send you to that post, but eh) Also to op, that avi is from a past hunt so unless ATA brings it back you can't get it D:
