In the 1960s, British-made lightweight open sports cars such as the Lotus Elan, MG MGB and Austin Healey were extremely popular in Europe and the USA. However, in the 1970s, emission regulations and revised crash safety regulations began to weed out these cars from the market, and by the 1980s, lightweight open sports cars themselves had almost disappeared from the market. It was against this backdrop that a new sports car was planned by Mazda North America. In the 1980s, a member of the development department at Mazda's North American technical centre said, "If only there was a lightweight car like the MG", and this sparked the development of a lightweight open-air sports car by volunteers, mainly from Mazda staff in North America. In 1986, the project by the volunteers was approved by Mazda's planning committee and the development project was officially launched. However, at the start of the project, it was far from smooth sailing, as the number of people working on the Roadster (MX-5) was small and there was much opposition to the project within Mazda. Despite these circumstances, Mazda's engineers poured their utmost passion into the development of the MX-5. The development concept was "Jinba Ittai" (rider and horse as one), and Mazda's engineers poured all the elements they could think of to bring driving pleasure, including a 50:50 front-rear weight distribution, compact body size, FR drive layout, a vehicle weight of less than one tonne, low centre of gravity and low moment of inertia. On the other hand, in order to generate sales volume, a low price had to be achieved. Therefore, the existing engine and gearbox were used to reduce costs and achieve an affordable selling price. However, Mazda did not compromise on the chassis in order to realise 'Jinba Ittai' (rider and horse as one), for example by equipping it with Mazda's first high-cost double wishbones front and rear. When sales began in 1989, the Roadster (MX-5) became extremely popular all over the world thanks to its affordable price and excellent handling. This was a phenomenal sales record for a two-seater convertible. As a result, a wide variety of followers were sold by many manufacturers worldwide from the 1990s onwards. Later, due to profitability and market needs, many manufacturers other than Mazda stopped selling two-seater open sports cars, or increased the price and body size of the two-seater open cars they sold. On the other hand, Mazda continued to produce the Roadster (MX-5) and maintained its development policy of 'Jinba Ittai' (rider and horse as one), and kept the lightweight, affordable, lightweight open-air sports car. The Roadster (MX-5), which continued to be a lightweight open sports car through model changes, became a car loved by many enthusiasts around the world. As a result, in April 2016, when the fourth generation, the ND model, was manufactured, the total sales of all generations reached one million units, setting an unprecedented milestone for a convertible car. This vehicle is the first generation of the Roadster (MX-5), the NA model. It was a phenomenal sales success for a two-seater open sports car, and is still loved by many enthusiasts around the world as a customisation base and sports car.

In the 1930s, the Neuroi, enemies of mankind, suddenly appeared mainly in Europe. The Neuroi are difficult to destroy with conventional weapons, and only girls with special magical powers, known as Witches, are able to fight them... Brave Witches is the story between the first and second seasons of Strike Witches. In September 1944, thanks to the activities of the Allied Forces, led by the 501st Joint Combat Wing 'Strike Witches', the Neuroi nest over the Republic of Gallia was obliterated and the safety of western Europe was secured. Taking this opportunity, the Allied Forces planned a full-scale counterinsurgency operation in central and eastern Europe. The 502nd Joint Combat Wing "Brave Witches", based in Petersburg in the Orasya Empire, was also about to be ordered to go into action. With the hope of humanity on their backs, these courageous Witches run across the cold Eastern European skies.
