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.

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.
