Sougo is at risk of being unable to graduate unless he passes his final examination! Sougo starts to focus and study hard but he dozes off and starts to dream again. In his dream he sees a future where humans and machines confront each other, as well as Kamen Rider Kikai!


"According to this book, average high schooler Sougo Tokiwa embarks on a path which leads him to become the demonic king of time, Ohma Zi-O. He defeats the alternate self of Shinji Kido (Kamen Rider Ryuki) known as Another Ryuga and evolves into Kamen Rider Zi-O II, who can see into the future. Of course, the other me, White Woz isn't going to stand for this. His goal is for Geiz to evolve into GeizRevive."
