It is located to the right of the Driver and slides over the Beam Equipper when the Driver is not in use or when removing a Progrisekey.

Rise Liberator ( ライズリベレーター, Raizuriberētā) - The Hiden Zero-One Driver's safeguard mechanism.

Additionally, it mounts suit and armor parts onto the wearer. Irradiation takes place within the Progrise Reactor. It utilizes a special lens that can convert a Progrisekey's Rider Model into Zero-One's 'Rise Architector' bodysuit via special moulding beams.

Beam Equipper ( ビームエクイッパー, Bīmu Ekuippā) - The Hiden Zero-One Driver's irradiation device.

The Authoriser can read a Progrisekey's status even without contact. When initiating a boosted deathblow (by pressing another Progrisekey against it), the Authoriser authorizes different up to six levels of attacks. By pressing a Progrisekey against it, it is 'authorized', unlocking the Progrisekey via an authentication code.

Authoriser ( オーソライザー, Ōsoraizā) - A device located to the Driver's left.

The surplus energy that is generated during this progrise process become photons, and when the Progrise Reactor's furnace is filled, a chamber effect reflects waves, increasing the internal pressure and thus accelerating reactor speed (creating better reactions). It is a device that performs 'progrise' operations by converting the inserted Progrisekey's Rider Model (the Key's graphic of an animal skeleton) into a physical form that maximizes that organism's unique abilities and converts that form into a shape that allows humans to better interact with it (in short, it creates a giant animal projection that turns into Zero-One's armor). Located within the central circular section of the Driver.

Progrise Reactor ( プログライズリアクター, Puroguraizu Riakutā) - The Hiden Zero-One Driver's main energy reactor.

By loading a Progrisekey, it connects the device into an internal Rise Port ( ライズポート, Raizu Pōto), a device that allows the Driver to read and learn the Progrisekey's abilities. Rise Slot ( ライズスロット, Raizu Surotto) - A slot intended to insert Progrisekeys into.

The Hiden Zero-One Driver is composed of the following parts:
