School life with armed girls
The story is set in a world where "Judo" (The Way of the Gun), a modern martial art born about 50 years ago, has become widely popular. Judo utilizes competition-specific firearms that are as close as possible to real guns, aiming to cultivate not only marksmanship but also courage, composure, discipline, and etiquette. There are two main categories: the "Competitive Shooting Division," where participants compete in accuracy and speed against targets, and the "Opponent Shooting Division," where athletes fire directly at each other using special non-lethal "Judo Regulation Rounds." While these rounds do not cause injury or death, they carry a sharp sting and splatter blood-like paint upon impact. Consequently, opponent shooting has gained massive popularity among the youth as an extreme sport with the tension of actual combat. The heart of the story is Ryosei Private Academy, a school centered on Judo education under the motto "To foster individuals who are strong, resilient, and become stars that shine upon the world." Due to a free-spirited school culture that respects autonomy, there are no unified regulations for equipment; students are free to choose firearms and gear according to their preferences and roles. Many students favor equipment derived from Western nations. At Ryosei Academy, the "Stella Squad" is a high-caliber team active in the Opponent Shooting Division, consisting of five members: Chika, Akane, Ao, Shino, and Shiori. The story unfolds around their Judo competitions and daily school life.
