Girori is a concierge of the Desire Grand Prix. He provides hospitality for the Kamen Riders at the Temple of Desire.
Girori secretly operates the DGP as the Game Master. He oversees and sets the rules of each game. He wears a mask and cloak to conceal his identity from the Riders. The Desire Grand Prix's staff are the only ones aware of his identity as the Game Master, notably Tsumuri and Hareruya Win.
Becoming frustrated with Ukiyo Ace's winning streak and his attempts to get closer to the staff, Girori increases the difficulty of each game, as attempts to stop Ace from uncovering the secrets behind the Desire Grand Prix. He assigned Win the task of outcompeting Ace.
As punishment for attempting to have Ace dropped out of the DGP, Girori was erased from existence by the DGP's Producer.
By unknown means, Girori was among several Game Masters that were revived for the final DGP initiated by Sueru.
Having learned about Ace's strive towards creating a world of happiness and fair play, Girori helps Ace infiltrate Sueru's location to confront the latter.
