Gamer Driver

Gamer Driver (ゲーマードライバー) is a transformation belt for the Ex-Aid Riders.

History
A Gamer Driver is being transported by Asuna Karino when she runs into Emu Hojo, who takes and uses the Driver to become Kamen Rider Ex-Aid to save Sota Suyama from the Bugster infection. At the same time, Hiiro Kagami has already been in possession of one for an unknown period of time.

Playable games
It is revealed that the Gamer Driver has a set list of playable games from corresponding Rider Gashats, and when all Bugsters are defeated in a game, a projection from the belt states "Game Clear!" over the corresponding image of the Gashat in the Driver.
 * Mighty Action X
 * Taddle Quest
 * BangBang Shooting
 * Bakusou Bike
 * Gekitotsu Robot
 * DoReMiFa Beat
 * GiriGiri Chanbara

By pressing the button on the Kimewaza Slot Holder without any Gashat inserted in it, the gamer can choose one setting from an offered list. It is yet unknown how exactly this function works.
 * A modern, bright city.
 * A racetrack.
 * A dark city at night.
 * A blue sky.
 * A beach.
 * A lake surrounded by trees.
 * At least one other setting.
