Naja Gref (ナジャ・グレフNaja Gurefu?, romanized as Nadja Gref in the anime adaptation) is a half human half silverwolf Feral who wields wind and fire wheels in battle. An intellectual, he always insists he is right, even when he clearly isn't. He is also extremely fond of his human mother. Naja is a member of the World Salvation Committee, but faces considerable prejudice and discrimination because of his half-human heritage. He also displayed the ability to transform for his special attack, but did not appear to be able to do so in the anime. In the anime, he is not a fighter but is never wrong in his calculations on where the World Destruction Committee is at.
