Rentaro Kagura

"Shinobi is written as heart of blade! Kamen Rider Shinobi!"

- Shinobi's introduction to Sougo.

Rentaro Kagura (神蔵 蓮太郎) is Kamen Rider Shinobi (仮面ライダーシノビ), a Rider from the year 2022 of Geiz Revive's timeline who appears in Kamen Rider Zi-O. His powers however were stolen in 2022 and reduced into an Another Ridewatch, where it made its way to Rentaro of 2019 and turned him into Another Shinobi (アナザーシノビ).

2019
After being beaten by thugs when standing up for a friend, Rentaro's desire for strength reaches Heure, who imbued him with the Shinobi Anotherwatch, transforming him into his corrupted future self. With his newfound ability, Shinobi went on a vigilante spree, killing the thugs from earlier before fighting against Zi-O and Geiz. Shinobi was subjected to the alternate Woz's future manipulation, first attacking Zi-O when he was spirited by his original iteration and second after being left defenceless against Kamen Rider Woz. Although he was doubted by his actions, the Anotherwatch influences him to become a king and continue hunting earlier thugs. Sougo's words of encouragement, however, reach him, allowing Rentaro to give a futile resistance against Sworz. With the Shinobi Ridewatch obtained, White Woz uses it to assume Futurering Shinobi and put an end to the Another Rider, saving Rentaro and destroying the Ridewatch.

2022
As a result of Oma Zi-O's destruction in the Day of Oma, Rentaro Kagura becomes Kamen Rider Shinobi in the future. When Sougo dreams of being in the New Year’s Day of 2022, Rentaro rescued him from a team of Stardust Ninja Dustards. When Sworz came into 2022, he harvested the Shinobi Anotherwatch, removing Rentaro of his powers and the Dustards he was fighting against.

Rentaro is a brave, strong-willed individual who protects the weak from those who misuse their powers for evil in 2022.
