No matter what predicament he falls in, he smiles and has a positive outlook. Even though he was told that he'll become the demon king who will rule the world 50 years in the future by Tsukuyomi, he use this as his motivation to become a king who realizes the happiness of his people.
Junichiro on the other hand, is Sougo's uncle and the owner of Kujigojido, a watch shop. He specializes in watches, but is also handy when it comes to repairing electric appliances. Despite the warnings about Sougo's future, he provides a gentle guidance to his nephew. He allows Geiz and Tsukuyomi to live with Sougo and even makes lunches for them. He also enjoys casually dropping hints about past Kamen Riders.
Fighting our heroes is a mysterious group called Time Jackers, another group of fighters from the future who are also fighting against the demon king. The Time Jackers give different people who they want to replace past Kamen Riders devices called "Another Watches" for them to become "Another Riders", the monsters in this series. These creatures are based on the designs of past Kamen Riders. The first few members of this group that we will meet in the series are:
Aura (played by Ayaka Konno), whose job is to create Another Riders in pursuit of a new king. Unlike Wool, she has a much calmer personality.
Schwartz (played by Kentaro Kanesaki), a powerful member of the Time Jackers as he has the ability to completely stop the flow of time. He's older than Wool and Aura and looks down on them due to his seniority. Also unlike the two, who talk to people into becoming Another Riders, he forces them to transform into one.
