Kuze is a full cyborg and is a main suspect in Section 9s investigation of the Individual Eleven. He is unusual among prostheticized individuals since he has chosen to have a sculpted face, which is far more difficult to manipulate than a standard prosthetic face. Due to this, Kuze's mouth typically remains motionless while he speaks.

Hideo Kuze is one of the known eleven members of the terrorist group known as the "Individual Eleven." During a mass suicide by the Individual Eleven, Kuze alone survived, leaving and hiding out in the Refugee Residential District. He spearheads a revolutionary socialist independence movement by the refugees in Japan.
