Elias "Ace" Honō, a Florida native born May 3, begins the main events at approximately ten years old with blood type AB. His father, a fireman and fire disaster expert, significantly shaped his career path and fire expertise. Ace serves as the Robo Master for Fire Robo on the Red Wings team, specializing in firefighting and fire prevention rescue.

He possesses a strong sense of self-reliance, positioning himself as someone teammates can depend on entirely. This drive sometimes manifests as overconfidence, leading him to believe he can handle situations single-handedly without sufficient teamwork. His competitive nature is evident early on, frequently clashing with peers like Taiyō Ōzora, Makoto Aikawa, and Daichi Hayami during training and missions.

His background instilled a highly knowledgeable, proactive approach to fire emergencies, aligning with his rescue specialist role. He tackles challenges methodically, though his initial preference for individual action over collaboration creates occasional operational friction. Team experiences gradually refine his understanding of mutual reliance during critical rescues.

Following active duty, Ace volunteers as an instructor for the next MRR program generation. This role leverages his accumulated expertise, marking a shift from individual capability to training new talents. His commitment to guiding others reflects growth beyond his earlier self-sufficient mindset and dedication to the organization's future.
