Used once. Woz Sense Folding fan Series: Heisei Riders Kamen Rider Zi-O This is the 20th anniversary work of the Heisei Kamen Rider series and the last work in the TV series [6][7]. In connection with this, a commemorative logo mark "Since 2000 Heisei 20 Kamen Rider Kicks" was newly created and used on the official website, related products, and when the opening title was displayed. In this work, which features a clock motif, the Kamen Riders, including the protagonist Zi-O, are positioned as "time travel riders" who travel through time and space to fight [8]. The element of time travel, which includes the eras of each work from the first work, "Kamen Rider Kuuga," to the 19th work, "Kamen Rider Build," and the setting that Zi-O is the "future demon king," is due to the ambition for a grand scale befitting the 20th work [9]. Woz (Black Woz) / Kamen Rider Woz A mysterious young man who appears from the future and reveres Sougo and Ohma Zi-O as his master ("My Demon King"). He also serves as a storyteller in the avant-title, etc. [ep 9]. He always carries a book of prophecy called the Oma Rinri Calendar, which records the legitimate history, and under the purpose of "correctly guiding Sougo," he mutters words that predict the future to Sougo, such as "According to this book..." [44][45], and gives Sougo the Ziku-Driver when he decides to become the best and greatest demon king [ep 2]. He shows a cooperative attitude towards him, but he is only worshiping Ohma Zi-O, and as mentioned later, he sometimes takes an overbearing attitude towards the 18-year-old Sougo.
