The Kaixa Driver (カイザドライバー Kaiza Doraibā), designated "SB-913B" is a transformation device developed by Smart Brain as a means to protect the Orphnoch King. The Kaixa Driver was designed for specific compatibility with the Kaixa Phone, generating the photon streams that form the Kaixa Armor when the Mission Memory is installed into the phone. If the belt is removed, the armor dissolves. The Kaixa Driver was destroyed by the Arch Orphnoch in the series finale and dissolved after Keitaro Kikuchi used it in the movie.
