Accepting his fate as the Destroyer of Worlds, Tsukasa has been fighting Kamen Riders, carding the search group of Skyrider, Super-1, and Kabuto, before running into a group of Riotroopers under Yusuke. Elsewhere, Daiki Kaito visits the Hikari Studio, convincing Natsumi to destroy Tsukasa’s camera and photos, as they are only bittersweet memories of what used to be. By then, Decade’s fight with Kamen Rider J enters their dimension as he uses Kamen Rider G4’s Gigant and the Side Basher to card J. Confronted by the Riotroopers, a young girl named Yuriko Misaki arrives and becomes Electro-Wave Human Tackle to take down the Riotroopers. She follows Tsukasa as he runs into Natsumi and Yusuke, who intends to stop Decade regardless of his injuries from the aftermath of Kamen Rider J’s destruction. After explaining that he merely accepted his mission, Natsumi wants Tsukasa to remember who he was. However, Tsukasa throws his camera because he has no memories of Natsumi. Natsumi feels powerless until Kivala arrives to remind Natsumi of Narutaki’s words that only she can defeat Decade, offering her power to ensure it…

It is the holiday season and Shotaro Hidari reminisces of the first Christmas he spent with his mentor, the great Soukichi Narumi, until Akiko Narumi breaks him out of his daydream so they can decorate the office. However, a woman arrives, revealed to be pop star Asami Mutsuki. She has come to the Narumi Detective Agency because she has been constantly haunted by the apparent ghost of her sister and pop star partner Erika who died in a boating accident a year ago. Shotaro takes the case, with Phillip intrigued as ghosts should not exist. The whole group investigates, with the Fuuto Irregulars hunting down clues in their own way, as Shotaro and Akiko visit Erika’s grave and speak with the cemetery’s caretaker Father Roberto Shijima, who Shotaro finds suspicious. As they leave, they find Erika and pursue her before being attacked by the Death Dopant. After calling to Phillip, Shotaro transforms to fight the Dopant who escapes as Shotaro confronted by his old boss: Soukichi Narumi. Soukichi produces the Lost Driver and the Skull Memory, transforming into Kamen Rider Skull. Double and Skull fight, with Shotaro reluctant to fight his mentor and Philip reminding him that Soukichi should be dead. Akiko overhears this as Double is taken down by Skull, with Soukichi warning him not to investigate any further. Shotaro decides to quit the detective business while Akiko insists that he stay on the case. The next day, Shotaro goes to the last known resting place of Soukichi Narumi: the island where he and Phillip first met. Phillip is already there, and tells Shotaro that if they are going to solve this case and find out why Soukichi is still alive, they must remember what happened on the night that he died: the Begins Night.
