Kota Kazuraba

"Let's finish this !"

- Gaim's slogan while arriving at the World of Monsters

Kota Kazuraba (葛葉 紘汰) is Kamen Rider Gaim (仮面ライダー鎧武), the protagonist of the show.

Gaim
Kota is the 2nd dancer for "Team Gaim" along with Mitsuzane Kureshima whom he sees as a little brother figure, but eventually stopped playing the game and left to look for a job in order to protect his lonely sister, Akira Kazuraba. He accidentally found his Sengoku Driver and was given a pair of Lockseeds (Orange and Pineapple) by a mysterious lady in white.

Wizard
"Did somebody call for help?!!"

- Kota hearing the childrens' plea

Kota hears the children crying for help and enters the portal, which takes him to the location of Wizard and Beast. When he arrives, he is immediately transformed and fights off the monsters. Afterwards, he introduces himself as Gaim to the other Riders.

After introducing himself to the Riders, Gaim goes back to his world just before the portal closes. He later arrives to help the Riders in the final battle with Amadam. During the battle, he learns of the Kamen Riders, and learns that he himself has inherited the title of Kamen Rider, promptly dubbing himself "Kamen Rider Gaim". After Amadam is defeated, Gaim vanishes back to his world.

Personality
Similar to Eiji Hino or Kamen Rider OOO, Kota is a type of person whom easily concerns with protecting everyone and due to this, "protecting people" is his very reason in fighting when it comes to his duty as a Kamen Rider.

Arms
Kamen Rider Gaim's forms are called Arms (アームズ).
