User blog comment:Ncduru/Who is Anna?/@comment-4999650-20151211101511

My prediction is that Anna is related to Hisui, which would make her Anna E. Fiore. Aside from both being Celestial Spirit Mages, Anna was dressed oddly similar to Hisui's "battle" appearance when she handled the gate herself. It would also make sense as to why Hisui even has access to the Gate, as it is in their family's possession. Hisui also seemed to have left an impression on Zirconis, which is quite trivial but it happened nonetheless, which ties her with the Dragons a bit more. Another trivial yet cute tie-in with my theory would be if Anna was the one that colonized Fiore or something, unless it was already established. Nonetheless, I just figured Anna would be a pinnacle character, especially since she's relevant to Zeref.
