Terui and Katsuragi learn from a surviving pickpocket that the pickpocketing ring's leader has the item. Arriving at a den of thieves, Terui discovers the item Katsuragi stole is a Gaia Memory Enhancing Adapter and takes it from the crime boss. Terui and Katsuragi arrive at the rendezvous point, but Ohno attempts to arrest Terui until Sagami arrives and kidnaps Katsuragi, who reveals he is the Commander Dopant.

Years prior, following a fatal car crash, Foundation X scientist Maria revives her son Katsumi Daido as an undead Necro-Over. Despite the experiment being a success, Foundation X abandons the Daidos and the Necro-Over project in favor of the Museum's Gaia Memories. Swearing revenge, Daido goes on to form the mercenary group NEVER and recruits expert marksman Ken Ashihara, former Yakuza subordinate Kyosui Izumi, strongman Gozo Domoto, and serial criminal Reika Hanehara after turning them into Necro-Overs. Sometime later, NEVER heads into a Southeast Asian country to kill the leader of a terrorist cell, only to learn a Quark named Mina beat them to it. She overpowers the mercenaries, but Daido defeats her and spares her upon learning she was forced to fight. Following introductions, Mina's fellow Quarks Lloyd and Shion arrive to take her back to their leader, Doctor Prospect of Foundation X. Daido and Hanehara attempt to stop the Quarks, but are stopped by Jun Kazu. Daido finds himself inexplicably attracted to Kazu's Eternal Gaia Memory, negating the latter's Rider powers. In response, Kazu uses his psychic powers to subdue Daido and Hanehara while Mina surrenders. Daido comes to amongst Foundation X's Quark prisoners. A fight ensues until Mina stops them, seeing something in Daido that Prospect lacks. When Prospect arrives and reveals he controls the Quarks via his Dopant powers, Daido attempts to kill him, but Prospect overpowers him until a recently freed Hanehara spirits her leader away. While returning Daido's harmonica, Mina accidentally accesses his memories and reveals he will not be able to succeed in freeing the Quarks due to the Heaven's Fall barrier around the Quarks' camp. Refusing to listen, Daido and Hanehara inspire the Quarks to rebel. While NEVER leads the Quarks in fighting Foundation X, Daido leaves to face Prospect. Kazu impedes him, having acquired Dopant powers to replace his Rider powers, but Daido synchronizes with the Eternal Memory and utilizes Kazu's Rider equipment to kill him and destroy the Heaven's Fall controls. As NEVER evacuates the Quarks, Prospect attacks Daido, revealing all the latter did was ensure their deaths. A horrified Daido attempts to reach the Quarks, but Prospect uses his powers to kill them before they can leave the complex. Prospect gloats over Daido, believing he broke the latter. However, Daido goes insane and thanks Prospect for reminding him that all people are devils before killing Prospect with NEVER's help, losing the Eternal Memory in the process. Refusing to revive Mina as a Necro-Over at Hanehara's request, Daido decides to seek revenge on the Museum by destroying Fuuto. Unbeknownst to NEVER, Foundation X takes Kazu's body to revive him as a Necro-Over while Mina awakens. In the present, Mina learns Daido was killed by Shotaro Hidari and Philip and attempts to seek revenge on them. After restraining her, the pair demand answers, but are caught off-guard when she reveals she knew Daido as a hero before recounting his story.
