Rozhar (ローザー, Rōzā) is an Arrancar who is regularly known by the alias Vincenzo Montferrand (ビンセンゾモントフェランド, Binsenzo Montoferando). He was formerly a member of Sōsuke Aizen's Arrancar Army and was one of Las Noches' guardians, albeit he was on the opposite side to where Ichigo Kurosaki and his friends arrived from. He is currently affiliated to Kagura and partners with Rosa, the former who gave him a much greater power in exchange for subservience.
