So... You're thinking, who will be the 7th master? Well!

Five candidates:

1. Lucy

She's the main character, but one of the newer members. Presumably not.

2. Natsu

He's a lot stronger than in Tenrou arc. But Guild master? What a crazy idea (he is a town destroyer and a vandal (Chapter 419)), so presumably not.

3. Erza

The strongest female member and a S-rang-mage of fairy tail. Not a bad idea, but maybe not.

4. Mirajane

The ex-assistant of Makarov and a S-rang-mage of fairy tail. Presumably the new guild master. (I don't pick on her, i assume she would it be).

5. Laxus

Well, that you would have liked! Remember, he was Ax-Crazy to do this. So presumably not.
