Yura Yamato begins her time at the high school section of Stella Women's Academy and is approached by Sonora Kashima, a third-year student who leads the C³ club focused on military survival games. The club consists of two second-year members—Karila Hatsuse, who is part-Japanese, and Honoka Mutsu, who uses a G36K weapon—as well as two new students: Rento Kirishima, whose family owns a Japanese sweets shop, and Yachiyo Hinata, who is very short.
