The finals of the Desire Grand Prix are underway when Keiwa Sakurai, a man down on his luck after a failed job interview, is caught in the midst of things.

Ace has won the Desire Grand Prix and the entrants for the next series assemble as they are tasked to go on a treasure hunt.

Neon is asked by her mother to quit her successful streaming channel when a new zombie round of the Desire Grand Prix begins; Ace and Michinaga have a bet on who will do better in the next round.

With Kanato and Neon infected, and tensions surrounding them high, the remaining contestants prepare for the finale wave of the zombie round.

Michinaga's job has him renovating Ace's house when they are called in for round three of the Desire Grand Prix: a duos battle that resembles a concentration-like card game.

In the midst of the duos round, the others find out that Morio is a wanted criminal as he proposes to Michinaga a change in partners.

Keiwa rediscovers childhood memories of what he wanted to be when he grew up; the final boss of this Desire Grand Prix has appeared, who has left previous games with no winner.

Keiwa's sister calls with news of a monster attack, but before the Kamen Riders can finish the round, Keiwa learns a shocking truth about his past.

Kicking the can becomes near impossible, bringing forth a new side-quest of hatching eggs.

Ace gets another wish for winning the Desire Grand Prix, now competing with a brand new set of competitors in a new game. A game which includes the staff controlled Punk Jack from last game.

The second round of this game has begun, transporting the players to an alternate dimension where they must each escort a civilian, with Keiwa being among the group of civilians.

While the players must figure out a Jyamato password to leave, Keiwa rediscovers his desire for a better world.

A mysterious girl appears to all of the remaining contestants, forcing a competition to reclaim their drivers.

Win and Ace both still lack drivers in order to continue in the Desire Grand Prix, while the Gamemaster takes things into his own hands.

It's time for Keiwa, Neon, and Michinaga to compete in the Desire Grand Prix finals, but things feel odd with Ace not here with them.

Keiwa and Neon are told that the next round is a hunt to take out Ace, but they and Tsumuri struggle with the gamemaster's decision for this illegal game.

A new gamemaster is in place and a new Desire Grand Prix is set in motion that sees the contestants living together to find a spy among them.

The contestants learn that they must vote on who the DisaStar is, and they will be ejected, no matter if they are the spy or not; Jamato arrive to compete in a sports game against the contestants.

The contestants continue their ball game as the time ticks away to place votes for the DisaStar.

A new game begins that involves the Jamato delivering bombs.

Sae must save her family from a bomb while Beroba puts together her own anti-Kamen Rider team.

The Jyamato haven't been sent out in a while, so a new game begins against the Gamemaster - a game of tag.

Beroba has taken Chirami's Driver, rendering the current round of the Desire Grand Prix null.

Ace, Keiwa and Neon talk with their supporters as the Desire Grand Prix is put on hold and replaced with a special episode.

Beroba starts up her own Jamato Grand Prix, but the Desire Grand Prix contestants refuse to sit idle as the Jamato run loose on the city.
