Kuzuu is a supporting character and a minor antagonist within the world of Future Boy Conan. He serves as a member of the Administration forces of Industria, the industrial nation state that opposes the protagonists. Specifically, he acts as a subordinate and right-hand man to Monsley, a high-ranking officer in the Industrian military. He is a 26-year-old man with dark brown hair and black eyes. His role in the narrative is that of a somewhat bumbling henchman. He is directly responsible for a pivotal act of early violence: during an altercation on Remnant Island, he fires the gun that causes a rocket explosion, an event that kills Conan's grandfather and sets the boy on his journey.

In terms of personality, Kuzuu is bossy and arrogant when in a position of power, but fundamentally weak-willed and lacking in intelligence. He frequently overestimates his own abilities and is easily startled or cowed when faced with genuine resistance. Despite his authority as an Industria soldier, he is repeatedly defeated and humiliated by Conan, often in a comedic fashion. He does not undergo meaningful character development and remains a static, minor obstacle throughout the story. His motivations are simple: he follows orders from Monsley and the Industria regime without displaying any deeper convictions or personal goals. His key relationship is with his superior Monsley, and his function is primarily to serve as a recurring, ineffective enemy whose failures highlight Conan's resourcefulness.
