The Hikari Studio arrives in a new A.R. World where, after seeing that Tsukasa's photos of this world are coming out perfectly, Natsumi realizes they may be in Tsukasa's home world. Finding a mansion depicted on the backdrop that took them here, Tsukasa and company enter and meet a girl named Sayo, who identifies Tsukasa as her older brother. Tsukasa still cannot remember as Sayo's caretaker Nobuhiko Tsukikage arrives to tell that Tsukasa's arrival has distorted the world and this can only be fixed by the strongest Kamen Rider existing in this world. After his memories return, Tsukasa orders Nobuhiko to summon every Rider for a tournament to determine the strongest one. After numerous matches, it comes down to a 6-man tag team match between the team of Decade, Kuuga, and Diend vs. V3, BLACK, and Super-1. Upon victory, Tsukasa and company end up into a giant castle with Yusuke and Natsumi finding themselves in the throne room surrounded by monsters. Eijiro appears shortly after, only to reveal himself as Doctor Shinigami. Yusuke and Natsumi learn that they are in Dai-Shocker's base of operations as the organization welcomes Tsukasa's return as Dai-Shocker's leader.

Ending up in the dungeon, Natsumi and Yusuke are ejected into the sewers while coping with these shocking revelations. The two escape to the Kadoya mansion, only to learn that Nobuhiko and Sayo are with Dai-Shocker as well. Nobuhiko reveals himself as Shadow Moon and Sayo uses the powers she has from the Stone of the Earth to attack Yusuke, unleashing the greatest and most dangerous of Kuuga's powers within him. Yusuke tells Natsumi to run away before the powers are unleashed. Nobuhiko and Sayo then approach Tsukasa, who reveal their plans to overthrow him. Sayo tells Tsukasa that she cannot forgive him for abandoning her and has now become High Priestess Bishium. Nobuhiko attacks Tsukasa with the Satan Saber and drops him into the sewers, where he is attacked by Yusuke as Kuuga Rising Ultimate Form, under the control of Sayo. Although Tsukasa escapes, Nobuhiko orders an attack on the city to eliminate all of Dai-Shocker's enemies. Tsukasa goes to the Hikari Studio to try to reconcile with Natsumi, who can no longer trust him knowing that he was the leader of Dai-Shocker. Tsukasa pleads with her as the Hikari Studio is now his only home, but Natsumi still refuses, as she is now alone in the world.

Later, Natsumi finds herself in the middle of Dai-Shocker's attack on the city when Narutaki comes to save her. They run off and are then saved by Daiki who had disguised himself as one of the attacking Dai-Shocker Soldiers. Narutaki tells Daiki that the only way to possibly save the world is to gather the rest of the Kamen Riders. Elsewhere, with no one to turn to, Tsukasa is confronted by Jōji Yūki who attempts to get revenge on him for having lost his arm while working for Dai-Shocker. He is about to finish Tsukasa off until he realizes that Tsukasa has changed and that he is now Dai-Shocker's target. Yūki pulls off his arm, revealing its robotic replacement and allows Tsukasa to escape as he prepares his transformation into Riderman. Back with Natsumi and Narutaki, Diend runs into Ohja and Kick Hopper and asks them to help fight Dai-Shocker, but the two Riders decide that they would rather side with Dai-Shocker instead. Diend summons Raia, Gai, and Punch Hopper to distract their new enemies as he flees the area with Natsumi. The two attempt to escape, but they are shortly ambushed by a Dai-Shocker platoon under General Jark as Tsukasa arrives, now intent on fighting Dai-Shocker and saving his friends. With Diend's help, Decade drives off the monsters as Jark is destroyed by Diend.

Making their way to Dai-Shocker's castle, Tsukasa, Natsumi and Daiki are confronted by the entire Dai-Shocker army led by Doctor Shinigami and Ambassador Hell as Ikadevil and Garagaranda respectively. Things seem bleak until all of the other Riders arrive to help. After Garagaranda and Ikadevil are destroyed, the Bishium-controlled Kamen Rider Kuuga Rising Ultimate arrives to kill Decade. Upon realizing that he is actually talking to his sister, Tsukasa makes Sayo realize that Shadow Moon is only using her to further his goals. Sayo realizes the error of her ways, and destroys the Stone of the Earth, freeing Yusuke of her control. Together, Decade and Kuuga Rising Ultimate Form fight Shadow Moon, but are overpowered. Before Shadow Moon could move in for the kill, the new Kamen Rider Double arrives. Double takes out Shadow Moon on their own before taking his leave, pinning Shadow Moon into the castle. All of the other Riders join Decade in an All Rider Kick, destroying Shadow Moon and the Dai-Shocker castle. The resulting shock revives King Dark as Diend arrives with Kamen Rider J. Using the Decadriver Final FormRide card, he turns Decade into the Jumbo Decadriver which then turns J into Decade Complete Form Jumbo Formation and he destroys King Dark with a variation of the Dimension Kick, using the other Riders as giant Kamen Ride Cards. After parting ways with the Riders, and making amends with Sayo, Tsukasa decides to continue his journey within the Hikari Studio, his true home, where Eijiro reappears as if nothing had happened.

So...Enjoy it ^^b
