Kamen Rider ZI-O

In the fall of 2018, a time machine appears before Sougo Tokiwa, a high schooler that has always dreamed of becoming a king. Then, Tsukuyomi appears from the time machine, telling Sougo, "I come from the year 2068, a world without hope where the Oma Zi-O, the king of time reigns supreme." She has come from the future in a desperate effort to change her own time. She then gives Sougo an ominous warning, "You will become Kamen Rider Zi-O, King of Time, the demonic king destined to rule the world." Can this really be Sougo's fate? This is the story of a Kamen Rider who would be king, who will fight to save the past, present, and future, encountering the various Heisei Kamen Riders throughout space-time.
