With Ren doubting his ability to go through killing other Kamen Riders, Shinji and Miyuki contemplate his possible paths and the potential doom that he faces. As Sanako decided to go out for her 'secret association meeting', Yui continues to investigate the truth behind the secret experiments her brother conducted. Meanwhile, Shuichi attempts to release a prisoner.
==Plot==
Ren was left injured, while Jun mocks him that he could not finish him off. Shinji on the other hand asks Jun that what's wrong with that and Jun said that it's a game. Miyuki eventually made a prediction of Jun that he will be confronted by the police. Jun, being ignorant eventually ignored the warning. Shinji tries to cheer Ren up that when Jun said is wrong, but Ren lost his temper and eventually faints.
