Who's the girl Panther Lily's with in the wedding dress pose off?
That is the daughter of Bisca and Alzack, Asuka Conell.

One year after the disappearance of the Team Tenrou, Fairy Tail Mages Alzack Connell and Bisca Mulan married each other and their relationship blossomed, eventually resulting in the birth of Asuka (&quot;A&quot; came from Alzack and &quot;-suka&quot; from Bisuka, the Romaji version of her mother's name).

I couldn't find the image, but I am sure it was Asuka in a wedding dress.
