Humans with insufficient DNA are rejected by the Faiz Gear with the word 'error'. Transforming into Kamen Rider Faiz burns Orphnoch DNA, so humans who have been implanted with this DNA will quickly run out and no longer be able to use the Faiz Gear.

Like most of the Rider Gears that Smart Brain developed, the Faiz Gear can only be worn by Orphnochs or humans implanted with Orphnoch DNA. The Faiz Gear had less power than the original Delta Gear, but had a much greater functionality. The Faiz Gear was the second set of Kamen Rider Gear developed by the Smart Brain Corporation to protect the Orphnoch King. Kamen Rider: Reiwa The First Generation Full list of appearances
