Hiromichi Gō is a Senior at St. Ishiyama High School, and participates in the Amateur Radio Club, and International Amateur ARDF Contest. He is a member of the Rokkesei, and the most violent member of the school, excluding Ishiyama transfers. He is ruthless and actively seeks fights, and attacked out of impulse once Mikki admitted that Oga was the strongest of the four who showed up for the rooftop fights. His advance was intercepted by Shintarou Natsume and the two had a reasonably matched fight.
