Kamen Rider Series

Mysterious monsters appear to attack the city and a team of Kamen Riders is assembled to fight them in a competition. One of such riders is Ace Ukiyo who can transform into the fox-like Kamen Rider Geats.

Keiwa, Neon, along with many others are chosen to participate the previous survival competition Desire Grand Prix. Among the participants happens to be the returning veterans who saved Keiwa and Neon from the previous competition, Ace and Michinaga.

Keiwa's trauma further increases following Takahito's death during the first bout of the new competition. While trying to get away from her strict mother, Neon happens to meet Ace and offers him to guest star on her live-streaming show. However, as Neon's show is interrupted, the second bout of D.G.P. suddenly begins. Somewhere, Michinaga is approached by Kanato, who offers an alliance with him, despite the former's claim that all Kamen Riders are enemies to him.

Neon is infected by a Zombie Jyamato's bite during Round 2 of the Zombie Survival-theme bout of D.G.P. while her mother deletes all of her streaming videos. As the third round begins, a certain accident occurs at the same time.

Nago is now cured and found a new way to live normally thanks to Keiwa. In response to Kanato's betrayal and disqualification, a mysterious A.I. Kamen Rider Punkjack replaces him to presumably accompany Morio on the third bout at D.G.P. admins' behest.

Keiwa's older sister, Sara has been kidnapped by a Knight Jyamato. Despite his injuries, Keiwa is re-motivated by Ace not to give up on saving Sara, while the latter apologize for using the former during its first round. After finding Sara's whereabouts, the four surviving Riders transforms in front of her. While Keiwa protects Sara, her hand accidentally touches her brother's Tycoon ID Core, revealing an unexplained terrifying past that Keiwa did not know about.

Although the can was kicked, Keiwa almost won but was ultimately eliminated, due being critically injured and thereby saved him from death. Sakurai siblings' parents was also revealed to be involved in some previous D.G.P., but somehow permanently died for some reasons, despite being civilians. Leaving only Ace, Neon, and Michinaga left in the D.G.P., who learn they must hatch eggs. Despite everything that has happened, Ace continues to fight as his desire to win only grows, while being moved to carry Keiwa's last wish to protect world peace.

As Ace becomes a Desire Deity once more, he suddenly calls Tsumuri "older sister", who considers Ace's world "unacceptable". He and Michinaga return for the new DGP tournament, along with Neon after she unexpectedly received permission from her father Kōsei. The three soon learn that they have been joined a mysterious guitarist named Win Hareruya, who reveals himself as the true identity of Punk Jack. Concurrently, Giroli is secretly revealed to be the DGP's masked game master as he privately entrusts Hareruya with important tasks.

The next bout of the "Stratagem" DGP sees the players helping vine-covered civilians, such as Keiwa, escape a Jyamato labyrinth and fighting a Jyamato that obtained the means to transform into a Kamen Rider-esque form. Meanwhile, the DGP's organizers secretly plot to eliminate Ace in retaliation for him making them part of his family.

As the players struggle to decipher a code that will let them escape a mansion and save the captured civilians from the Jyamato Riders, Win tries to give Michinaga tips on how to outwit Ace while finding their owns of escape. Meanwhile, knowing Keiwa will not survive the Jyamato Riders without his memories from the previous tournament, Ace asks him to touch the former's Desire Driver to restore them, leading to Keiwa eventually finding his own Desire Driver and returning to the DGP.

Keiwa rejoins the DGP after new player Ittetsu Tanba voluntarily gives up his place in the tournament to him and becomes motivated to revive those who have died in previous DGPs. However, he and the remaining players discover a mysterious woman in a white dress and red hat has stolen their Desire Drivers and given them to the Jyamato, forcing them to regain them quickly lest they risk getting disqualified.

Ace and Win compete to reclaim their Drivers back from a Jyamato Rider, with a pleased Girori confident that the former will finally lose. Concurrently, Michinaga fights to claim his own form of victory over Ace while Neon discovers her family's company has been sponsoring the DGP for generations and her bodyguards are former DGP players.

Following Win's failure, Giroli breaks the rules to become Kamen Rider Glare, brainwash Win into becoming his mindless servant, and eliminate Ace from the DGP personally. Meanwhile, Keiwa, Neon, and Michinaga struggle to win the "Conspiracy" tournament and potentially become the new "Desire Deity" until Ace suddenly appears, having retained some of his memories of the DGP.

Refusing to allow Ace to be declared the winner of the "Conspiracy" tournament, Girori sets up a new final round where either Keiwa or Neon could win if one of them kills Ace. While both are reluctant, Girori manipulates them with their desires to do his dirty work. Despite Girori's best efforts and turning Win into a suicide bomber, Keiwa and Neon play along until they are able to expose Girori's illegal actions during a broadcast, allowing the DGP's producer, Niramu, to officially fire him. Meanwhile, Michinaga's body ends up in Archimedel's garden.

As a new DGP gets underway under the direction of a new Game Master to replace the disgraced Girori, Ace, Keiwa, and Neon are joined by two new participants in spectacular fashion. This time however, new rules tailored to limit Ace's power become known, such as popularity reviews. Meanwhile, Michinaga awakens in Archimedel's garden, having been resurrected by his constant use of the Zombie Raise Buckle, and eventually learns the Jyamato have gained the ability to mimic fallen players' appearances.

The five competing Riders must team up against a Jyamato team in the tournament's ball-themed second round, "Jyamaball". In the middle of the match however, Keiwa is suddenly accused of being a traitor.

Following Daichi's elimination from the tournament and confirmation that he is not the Desire Star, the remaining players must find a fruit-shaped time bomb hidden by the Jyamato to identify the Desire Star in the next round. However, Keiwa's anxiety worsens while Michinaga's use of his Jyamato Buckle gradually takes his humanity. Meanwhile, Keiwa's older sister Sara gets caught in the crossfire of the DGP after unknowingly buying a pineapple-shaped bomb from a Bomber Jyamato. After being rescued, she reaffirms her desire to support her family.

Sae discovers she has become the Desire Star and must complete a Secret Mission. However, she also learns her remaining family were taken hostage the previous round. She and her fellow players attempt to rescue them, but Michinaga goes berserk once again, taking the Zombie Buckle back from her due to Beroba, a fan of his and the Jyamato's sponsor who seeks to obliterate all of the Riders, until the mysterious Kamen Rider Gazer arrives to put an end of their madness.

Due to the Jyamato not appearing in the latest round, the DGP's producers fear their ratings will decline and make the Riders compete in a modified form of tag wherein they must capture Chirami, who reveals he was forced to become the Game Master before running away. Meanwhile, Beroba and Michinaga gather at the Jyamar Garden as a new plan unfolds.

On Neon's birthday, Michinaga uses the Vision Driver he stole to establish a one-on-one fight with Ace in the JGP's final round. However, Beroba has her own plans for the round.

To end the JGP and reunite with his mother, Ace challenges Michinaga to a duel.

As the winner of the JGP, Michinaga resets the world and Neon lives her days in peace with no memories about her days as a Kamen Rider while Ace, Keiwa and Niram have gone missing. However, Chirami and Ziin decide to challenge Michinaga in order to bring them back.

With surviving Jyamato hiding themselves as miniature parasites that can infect civilians and infiltrate society to cause chaos, along with Kekera and Beroba being up to no good, Ace, Win and Tsumuri recruit Keiwa and Michinaga when the former sets up a friendly contest between them to deal with the troublemakers. It is eventually revealed that Daichi took over Archimedel's legacy on further evolving the Jyamato. Furthermore, Suel sends a new Game Master, Jit, to the present era to retrieve Tsumuri. As consequence of the DPG now public knowledge, Kurama Zaibatsu suffers the consequences with Kōsei arrested for bribery and conspiracy. Thankfully, Neon was able to find an apartment with Sara as her roommate before the former got caught up in the scandal.

With help from Kekera and Beroba, Keiwa and Michinaga return to their Rider duties to join Ace in stopping the parasite Jyamatos' widespread infections on civilians caused by Daichi. In the midst of the crisis, Daichi kidnaps Sara, when she learns the source behind the existence of the parasite Jyamato.

With the Parasite Jyamato round over, Keiwa's wish to revive those who were victims of the previous DGPs and free those who were trapped inside Jyamar Tree, such as Sara, has been granted.

Michinaga and Ace attempt to save Keiwa from himself, but he refuses to listen while consumed in darkness over him indirectly killing his family with a wish that was meant to bring them back. This forces Ace to confront Keiwa's inner demon, whose existence was alluded in the first Desire Royale, and fights him to save Keiwa. Meanwhile, with Kōsei hospitalized, Neon learns that the events that caused Akari's death were caused by Beroba for her own amusement. Regaining her ability to become Na-Go while entrusted with the Fantasy Raise Buckle, Neon decides to put an end to Beroba for the suffering she brought to her family.

Beroba recruits Kanato Sumida, formerly Kamen Rider Dapaan, to help her get revenge on Neon, for making her feel despair. Meanwhile, Keiwa resolves to defeat Ace, and turn Tsumuri into the Goddess of Creation. Win rescues Tsumuri from Jit's clutches. Furious, Jit fight and knock Win out. As the two battle, however, two mysterious people from the future watch on: Mela, Kamen Rider Cross Geats, and his assistant, Melo.

After deploying Win to rescue Tsumuri, Ace sacrifice his freedom by absorbing Tsumuri's power to prevent DGP from misusing it to enact misfortunate endings, and frees Keiwa from being manipulated by Kekera and Beroba and the organization. Furious by his own failure, Jit created an evil doppelgänger of Tsumuri. In response and concurrently, despite having no, Michinaga takes his risk dispose his and Keiwa's former supporters.

As Ace's life force as a God of Creation is starting to run out before he gets petrified, his friends must stop Jit and Kekera from destroying Earth, with a redeemed Keiwa must settle against his former supporter alone to atone his deed.

Suel's plan of the DGP's Series finale turns Earth into an apocalyptic war amongst everyone killing each other for a chance at happiness. Ace wants to end this game for the sake of his world, but is confronted by Black Tsumuri.

Tsumuri points her Magnum Shooter 40X at Ace... and a gunshot rings out! Was Ace shot?! A world where everyone can be happy, just what is Ace's true wish? For that... we witness the end!
