This article is about a/an ally in Kamen Rider Zero-One.

Satoshi Sakurai (桜井聡) was an employee of Hiden Intelligence in charge of Daybreak Town's Humagear Factory. He was partially responsible for the Daybreak Town Accident, which led to his son Go Sakurai attempting to discover the truth with Aruto Hiden and Isamu Fuwa. Approximately 12 years after his death, he was posthumously declared a hero.


Satoshi was an employee of Hiden Intelligence, and was made head of Daybreak Town's Humagear Factory. During the day the Humagears went rogue, he oversaw the evacuation of all personnel and civilians through the Central Control Center of the factory. Being that he was the only one left inside the building, he was the only one to receive the video message of MetsubouJinrai.net's messenger claiming the incident as their own doing. To prevent the terrorist group from gaining control of the Humagears, Satoshi shut-off all Factory Gates, leaving him trapped with the undeployed Humagears inside the factory. He then proceeded to blow up the Humagears in Daybreak to prevent them from escaping the towns' borders and attack more humans. As the Humagears inside the factory blew up with him still inside the control center, his last moments were shown to be thinking of his own son, Go.

Due to the first investigative committee learning the cause of the destruction originating from the factory, and that his remains were found inside the control center, it was concluded that the cause of the accident was faulty maintenance, with the public openly blaming Satoshi for the incident. His heroic actions were later revealed when Aruto and Fuwa went to investigate further, with his son finding a memory card containing footage of Satoshi's last moments.
