So when Nomura mentioned the "Master" of VAT and "Master" Xenahort, he was meaning...?
Aside from them. Those are the only masters confirmed to date.
VAT, DS, and the 14th
VAT and DS are in training.
14th has yet to be qualified because we don't know if her Keyblade is real or not.
I know there is some speculation on the validity of their keyblades, but they still wield.
That's only 14, everyone ASSUMES that VAT's Keyblades are fake.
And Sora has been referred to as a master, I believe.
Nope, Nomura spcifically called SRM "Heroes of Light"
