Sougo C

, alternatively known as , is a 3rd-year high school student at Misawa High School who transforms into .
==History==
===Meeting other Zi-O===
When the Elementary Inves attack lost students in the wasteland, Sougo arrives and transforms into Kamen Rider Zi-O to save them. He later arrives, where another fight happened with some Inves against Geiz, his main counterpart as well as another one. However, as he and the main Sougo are confused, the Hanazono Sougo feels interested in this situation. 
The Sougo from Misawa, now dubbed Sougo C, later attempts to become Hikarigamori's president in an election; compared to the efforts of Sougo A and B, he is seen bribing the students with sweets rather than truly placating them. At night, Sougo A catches him talking to an unknown individual (later revealed to be Misa Kuon plotting to kill Sougo A) after an Inves is let into the school; during lunch the following day, he claims that he had tried to stop the Inves as well before it escaped.
After Heure confesses to Sougo A, Sougo C runs into him, and suggests they trade places. After doing so, Heure is dropped off the school's roof by Sougo C with intent to feed him to the nearby Inves, causing Sougo A to intervene. Sougo C seems to be the winner while Sougo A seemed to perish in the process.
Later after Misa Kuon had pulled Sougo C aside to thank him for taking Sougo A out, Sougo C revealed himself to actually have been A all along. He revealed that to avoid Heure, C had swapped clothing with him. As for the result of the battle, it was actually another Kamen Rider who had killed C.
==Personality==
Sougo seems to be pretty self-confident and proud, but somewhat clumsy. His true skills, however, lie in his manipulation, bribing his classmates into voting for him and giving off the impression of being a villainous counterpart of Sougo A by appearing to hold Heure hostage to draw Sougo A out.
==Powers and Abilities==
His powers and abilities seem to be those of the original Sougo Tokiwa when he just became Zi-O. However, as mentioned above, he is also a keen manipulator.
