Woz reading the Ohma Advent Calendar

Through this book, Woz was aware that Sougo Tokiwa first transformed into Kamen Rider Zi-O, which Woz viewed as Sougo's first step to one day becoming King of the world. Traveling back to this day, Woz told Sougo that it would be a momentous one for him, but that he must beware the "red robot". Indeed, after Woz appeared, Sougo was attacked by the Time Mazine, a red-colored giant robot piloted by Geiz Myokoin, whom also travelled back from 2068. When Sougo unlocked the Zi-O Ridewatch, Woz appeared before him again and urged him to use his new power to shape the world to his will. Sougo, having been made aware by Tsukuyomi that Ohma Zi-O was the most despised tyrant in history, vowed to instead become the greatest and most beloved king. Though this came as a surprise to Woz, he nevertheless provided Sougo with the Ziku-Driver which enabled the youth to achieve his fated transformation into Kamen Rider Zi-O. Kingdom 2068

Following Zi-O's first battle, Woz informed Sougo that he was destined to rise as the ruler of time through a path of conquest. He also warned him of the Time Jackers who sought to impede his ascension in an attempt to groom others to become king. Soon after, Woz informed him that the emergence of Another Build has altered history, usurping Sento Kiryu as Kamen Rider Build. He warned Sougo that, even as a potential overlord, he was yet to acquire the ability to defeat Another Build, who was being engaged by Geiz in the meantime. Traveling to 2017, Woz caught up with Sougo as he accessed the Build Ridewatch, advising him that victory would include a great deal of responsibility. It was at this point that Sougo used the Ridewatch to assume the BuildArmor, commemorated by Woz as the first time Zi-O would receive the power of another Kamen Rider. Best Match 2017
