Since its introduction in 1984, the Honda NSR500 was a famous competition-only machine that dominated the WGP for a long time until it was handed over to its successor, the Honda RC211V, in 2002. Based on this design concept, the NSR50 is a racer-replica model that has been downsized by about three-quarters. In the 1980s, minibike racing and racer replicas were all the rage. Honda entered this market in earnest and launched the "NSR50" in 1987. The engine mounted on this model was a small-displacement, 2-stroke 50cc engine. Although it did not excel in terms of maximum speed or acceleration performance, the NSR50, which inherited the design of the works racer NSR500, boasted very good cornering performance and was unrivaled in speed on mini circuits. The excellent chassis design also made the NSR50 a very rare machine that is still active on the circuit today, more than a quarter of a century after its introduction. Production of the NSR50 was discontinued in 1999 due to exhaust gas regulations. It was loved by many fans, and its popularity has not diminished.

Madoka Kaname, a kind-hearted girl, is an ordinary eighth grader at Mitakihara Junior High School. One day, a mysterious creature who speaks human language and calls himself "Kyubee" appears before her. "I want you to make a contract with me and become a magical girl.” Kyubey says that he will grant Madoka one wish, anything, in exchange for becoming a magical girl and fighting the witches who bring misfortune to this world. The peaceful fate of Madoka and her surroundings begins to go awry. She is caught up in the great current that moves the world.

She is a third-year junior high school student who attends the same junior high school as Madoka. She is an active Puella Magi who has a contract with Kyubey. It is not unusual for magical girls to act out of self-interest, but she is an altruistic person who puts protecting people from witches' evil first. She is also very considerate of her younger colleagues. She is a good friend to Madoka and her friends, and is a reliable older sister. When she transforms into a Puella Magi, she uses a musket gun and a huge cannon as weapons. She is also one of the most powerful among the Puella Magi. When she shows her true potential, she clearly surpasses Homura Akemi, another top-level Puella Magi.
