Tsuyoshi Utada, one of twin brothers and joint Robo Masters of Gyro Robo in the Blue Sirens’ second rescue team, specializes in police interventions and road emergencies. Born November 16 in Tokyo, he shares an unspoken mental connection with his brother Susumu, allowing flawless coordination in high-pressure scenarios. Though minor rivalry surfaces, both prioritize neutrality during team disagreements, channeling energy into their rescue roles.

Recognizable by his right-parted hair and a "#2" shirt reflecting his self-effacing humor, Tsuyoshi combines technical brilliance with moments of doubt. Defying their father’s wrestling aspirations, the twins joined Machine Robo Rescue, applying engineering prowess to critical missions: diverting volcanic eruptions, stabilizing a collapsing dam breached by a rogue Gura Gorro, and rescuing civilians from tangled traffic disasters. During a family visit, a brotherly wrestling match turned urgent when their father became trapped underground, requiring collaborative ingenuity to free him—a feat that finally earned paternal pride and cemented their command of Gyro Robo.

Later operations included thwarting a high-speed train hijacking and venturing into space to recover stranded teammates. After graduation, Tsuyoshi relocated to New York with Susumu under an international rescue banner, battling global threats while maintaining their bond with Gyro Robo. Their synergy shone in both crises and camaraderie, exemplified by a playful trenchcoat disguise to covertly monitor a colleague.

Tsuyoshi evolved from a meticulous technician hesitant to take risks into a decisive leader unafraid of unorthodox tactics. His journey—marked by quiet resilience and growing self-assurance—solidified his role alongside Susumu as guardians of safety, blending calculated precision with adaptive problem-solving to protect communities worldwide.
