A young man devoted to his little brother Youta who's a fan of the Greatman TV show, particularly Greatman Red. Matsumoto joined the Right Trading Company because his father was a loyal company employee. Imagine his surprise when he learned that he was to wear a costume. During his job interview, he was asked what color a superhero should be by Kyoko Sakakibara. Remembering his brother's preference for Greatman Red, Hiroya's response of red would ironically be the color of his Pro-Suit.
