Emu follows a patient who’s fled in fear of a doctor and encounters Taiga, who transforms into Kamen Rider Snipe. Once Emu learns of the past connection Taiga had to CR, he visits the dark hospital Taiga resides in to rescue the patient.

Taiga tries to find out more about Emu's infection, and starts to discover the secret that might be why Kiriya was killed. Meanwhile, using data collected from fights with Mighty Brothers XX, Parad makes his move and reveals his new form: Kamen Rider Para-DX Level 50.

Emu thinks Taiga and Hiiro attacked him since he is the source of stress for Nico, who is suffering the Game Disease. He does not realize the true intention of the other two riders is to eliminate the Bugster virus residing in Emu himself, who is unknowingly infected with the disease as well.

Brave attacks Ex-Aid again but Revol Bugster and some grunts appear to…defend Emu! He is further convinced he is the source of Nico’s stress. Genm Level X appears and attacks both riders. He succeeds in stealing all of Hiiro’s Gashats and seems intent to do the same with Emu’s.

Thanks to the public announcement by the Ministry of Health, the number of Kamen Rider Chronicle players seems to have decreased significantly, which would subsequently reduce the amount of game disease patients. However, unbelievable information about Kamen Rider Chronicle is released by Ren Amagasaki, the new CEO of Genm Corp. There is a hidden component inside Kamen Rider Chronicle, one that is said to dramatically increase player participation! However, Taiga, who was suspicious of the love and go CEO's actions, goes into Genm Corp. to confront him himself...
