The Wolkenritter's familiar-like companion, a large blue wolf. He is not treated like a familiar but as a companion by the other knights and only responds to Hayate as his mistress. Despite this, he says that he, like a familiar, will help his master regardless of whether it is right or wrong. Zafira is called the Shielding Guardian Beast, though Arf (Fate Testarossa's familiar) claims that this is the same thing as a familiar. He transforms into a muscular dark-skinned man, wearing blue warrior-like clothes created by Hayate, and in battles, always finds himself facing Arf.
He then returns to his dog form as of StrikerS.
His seiyuu is Ichijou Kazuya.
