Description
Ken Sakuma is a character from the Japanese television series Kamen Rider V3, serving as an ally to the main protagonist for a portion of the story. His background is that of a professional agent working for Interpol, the international law enforcement agency. Within this organization, he holds the designation of Destron Hunter Number 5. The Destron Hunters appear to be a specialized unit within Interpol dedicated to combating the series' primary antagonist organization, Destron. Sakuma is presented as the sole survivor of this group after his comrades are systematically eliminated by Doctor G, a high-ranking Destron general.

His primary role in the narrative is to assist Kamen Rider V3. As an agent on the front lines of the fight against Destron, his motivations are intrinsically professional and personal; he is driven to stop a criminal organization that threatens global security and to avenge the fellow hunters who were killed in action. His expertise and resources from Interpol make him a valuable, if temporary, partner to the hero. Later expanded material, specifically the Kamen Rider Spirits manga continuity, depicts Sakuma's career progressing significantly. In this storyline, he rises to the position of head chief of Interpol. From this influential vantage point, he provides clandestine support to the ten Kamen Riders. This support takes a tangible form when he supplies equipment and resources to another character, Kazuya Taki, enabling Taki to operate as the combatant Skull Rider. Furthermore, he is credited with founding a mercenary group called Spirits, which he assigns to Taki and another individual named Anri to lead.

Regarding his key relationships within the primary television series, Ken Sakuma is explicitly listed among the allies of the hero Shiro Kazami, who transforms into Kamen Rider V3. This group of allies includes other recurring characters such as Tobei Tachibana, Junko Tama, and the Boys' Kamen Rider Squad. His development from a field agent and the last of the Destron Hunters in the original series to a high-ranking chief in Interpol who orchestrates support operations from the shadows is a notable aspect of his character arc, as explored in subsequent manga stories. While his precise combat abilities are not detailed in the source material for the original television show, his designation as a Destron Hunter implies he possesses considerable training in investigation, fieldcraft, and likely armed or unarmed combat to engage the forces of Destron directly. His notable ability, particularly in the later continuity, is his strategic acumen and his capacity to mobilize significant resources and personnel to aid the Kamen Riders without fighting on the front lines himself.
