Ono presides as president of Shibahama High School's Robot Club, relentlessly pursuing his dream to build and pilot a giant robot. He approaches robotics with intense passion, declaring it serious business.

He possesses short, shaggy hair that falls just below his ears. Thick black glasses conceal his eyes. Ono wears the standard male school uniform: a short blazer over a tie, matching pants, white socks, and brown loafers.

His key narrative action involves approaching the Eizouken club to request their help in increasing the Robot Club's popularity, initiating a collaboration with the main characters.
