It is a communication device that connects to the communications satellite Zea.

Back Radome ( バックレイドーム, Bakku Reidōmu) - A device located at the rear of the Driver's Hiden Linker belt strap.

When equipping a new Progrisekey, it moves to the centre, shifting the Driver into a data storage and backup standby state. When a Progrisekey is inserted into the Driver, it shifts to the Driver's right side, allowing the Progrise Reactor to start working. 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:
