Adding Zeref As a Playable Character if He Ever Gets Added

[ecetereis]

I think it's a good idea to add a character that's supposed to exist. According to this bond Zeref probably should be added as a character.

Well it's the same with Makarov, Ultear, Minerva, Seilah and Silver they are also bonds for different chars and I doubt Zeref will get added this early on.
