|This article is about a transformation device in Kamen Rider 555.|
The Transformation Belt SB-913B Kaixa Driver (変身ベルト ＳＢ－９１３Ｂ カイザドライバー, Henshin Beruto SB-913B Kaiza Doraibā) 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.
Kaixa Driver can be used by anyone with Orphnoch DNA. However, it will shorten the lifespan of the user in quick and user without a great amount of Orphnoch DNA will die in a short time.
