"Hiroshi Nakamura is one of the main characters in the Japanese manga ""Flaming Heaven: Valkyrie"". Hiroshi is a young man in his early 20s, with short black hair that is sometimes styled in a messy, spiky fashion. He stands at an average height and has a lean yet muscular build that is well-suited for his role as a pilot.

His relationships with his fellow pilots, such as his best friend and wingman Takashi, and with his love interest Rei, are a key part of his character development.
