I still think its her mom, because of what she asked to the king when she transformed the princess about his love for her (as a daughter) in that form. I supose it's related to the reason she left Erza
or it's about 2 elien girl.
Oh,is that so....I guess I wait for next chapter then....
I almost forgot about those two,maybe you're right.....
I hope they are mother and daughter, next chapter is probably Yukino meeting Angel, her sister
Ehh,yukino and sorano sisters???
Next chapter: Elder sis and younger sis,does these refer to Eileen and Erza,Noooo I thought she was her mommy......
