Tsukuda Kohei was once a researcher and engineer with the Aerospace and Science Exploration Agency and now runs Tsukuda Industries, a small factory which was left to him by his father. He accepted that the failure of a major launch was due to an inadequate item he produced and now struggles to design and supply a far better replacement. At the same time he also works on redesigning the engine and guidance systems of driverless tractors (imdb & me)
