I liked the chapter, Precth was awesome (even without Magic), Mavis is such a little genius. Yay, I get to see Zeref again!

Ok, so I know someone was talking about the Zeira theory, I don't know, I don't think Zeira is a illusion or just an imaginary friend. I think that is a spirit of Zeira, similar as to Mavis in present day being a spirit.

The reason for this is:

1. Yury seemed confused and felt bad when Mavis first introduced Zeira, almost as if there really isn't someone there. If it were an illusion then Yuri wouldn't looked like that and asked how old she was, and Mavis answered for her.

2. Mavis's illusion Magic seemed flawless, even Precth and the BS Mages was convinced that wolf was real. So if Zeira were an illusion, Yury wouldn't have been confused or felt bad for Mavis.

So in my theory, I think Zeira is a spirit, similar to Mavis being a spirit as well. I mean they are from Tenrou Island, anything is possible on Tenrou Island (that sounded pretty cheesy huh?). But anyway my point is, there could have been a point on the island that could saved Zeira's soul and manifest it so that Mavis doesn't have to be a lot.

And when Mavis' time comes, the same thing will happen to her as well. Something similar to Lost where someone has to be the protector of the "Island".

And I will not be convinced otherwise that at the very moment of Mavis's introduction when Acnologia attacked that was an illusion and all those times she appeared she was an illusion as well. I don't think illusions can cast Magic. And at the Magic Ball at the end of the GMG, Chelia even though she can't see Mavis she felt something weird happen.
