Mitsuru Sano

Kamen Rider Imperer (仮面ライダーインペラー, Kamen Raidā Inperā?) is one of the 13 Kamen Riders in the tokusatsu TV series Kamen Rider Ryuki. Kamen Rider Imperer appeared later in the series. He also appeared in the 13 Rider Special and Kamen Rider Ryuuki video game. His name is based on "Impala".

Fictional character biography
Although he came from an affluent family, Mitsuru Sano worked in a parking garage, occasionally cleaning rich people's cars. His father sent him out into the world so that he could learn the hardships of life and not be soiled by a rich upbringing. Because of his poor lifestyle, he believed friendship, respect, and love could be bought, and thus accepted Kanzaki's proposal to become a Kamen Rider in order to become rich and lead a happy life. After his father died, he inherited his father's business and became the boss of a major company. Because of his new found lifestyle, he wanted to give up the Rider war and enjoy his wealth. However, Kanzaki reminded him of his contract with the Gigazelles and what would happen to Sano if he did not fulfill his side of the contract with them.

Shaken, Sano decided to use part of his inheritance to buy the services of the other Riders. He first approached Shinji Kido and Ren Akiyama and offered them the money in exchange for their services, and was initially turned down. Sano tried the same tactics on Suichi Kitaoka, and seemingly succeeded. But Sano cancelled the contract days later after deeming Kitaoka "unreliable", and turned to Tiger for assistance. But Tiger back-stabbed Imperer and wounded him, leaving him for dead. Though he survived the attempt on his life Imperer is ambushed by Ohja while attempting to make his escape back to the real world. Ohja destroyed Imperer's card deck, making him unable to leave the Mirror World and dissolve within mintues, screaming and begging for help. But Kanzaki's changing time allows Sano to have a second chance at life.

Imperer is unique among the other Riders because unlike the rest of them, his color scheme is inconsistent with his respective monster. Being melee-based with Muay Thai-style attacks, Imperer doesn't have much fighting experience, using the Gazelle Visor (ガゼルバイザー, Gazeru Baizā?) on his right knee to use his Spin Vent card which gives him a double-drill Gazelle Stab gauntlet. Aside from his Spin Vent, Imperer relies on his mass amount of Zelles to do the fighting for him, after which he lands the final blow. His Final Vent Drive Divider (ドライブディバイダー, Doraibu Dibaidā?) has the Zelles stampede a target before Imperer unleashes a powerful knee strike to the enemy's head.

Contract Monster
Imperer is the only Rider to have more than one Advent Monster from the start (unlike Kamen Rider Ohja, who had to kill Kamen Rider Gai and Kamen Rider Raia to gain Metalgelas and Evildiver). Besides his contract monster, Gigazelle, he is also joined by Megazelle and Omegazelle because these Gazelle-type Mirror Monsters travel in groups. Although these monsters aided Imperer, he had no cards for the others, save for the primary Gigazelle; this sometimes results in Megazelle and Omegazelle attacking Imperer.

Gigazelle (ギガゼール, Gigazēru?): Resembled a cross between a gazelle and a humanoid.

* Height: 2.43 m

* Weight: 125 kg
