KivaArmor (キバアーマー,KibaĀmā) is a Kamen Rider Kiva-based form accessed by inserting the Kiva Ridewatch into the left-hand side of the Ziku-Driver. Its visor spells out "Kiva" (キバ,Kiba) and its shoulder pads are modeled after Kivat-bat the 3rd. This is the only Zi-O form with a yellow visor, like Kiva's base form (While other forms' visors are pink).
This form's finisher is the Wake Up Time Break (ウェイクアップタイムブレイク,Weiku Appu Taimu Bureiku).
Jiro was in possession of the Kiva Ridewatch. After a brief fight, he gave the Ridewatch to Sougo Tokiwa, saying he believes that Sougo is the person he's been looking to give the Ridewatch to. 2019: First Love, Finally!
