Driver System

The Driver System (ドライバーシステム) is the backbone of the various transformation gears used by the Riders in Kamen Rider Nio. Developed by Uzikiri, "the first bit of real science in Kegare since the beginning", it was originally meant to bring the Enmi deeper under the Nasi's corruption. However, during the Full Caste's first encarnation, a prototype was stolen, reverse-engineered, and modified by the Kane Shrine, leading to the development of the Toriiver and through it the Chain-linker. The plans for Kamen Rider Majokko's belt were intentionally planted by Uzikiri, and due to its user's non-Enmi DNA using it causes her considerable pain and internal damage. The Toriiver Black powering the Kamen Rider Maō transformation is the only one originally designed for human use; its components can be used to modify other belts for safe use by non-Enmi. Only the gear used for Kamen Rider Daimaō is considered entirely faithful to Uzikiri's original vision.
