Stella Jogakuin narrates the adventures of Yamato Yura, which was just entering the Institute Stella Academy for girls and Kashima Sonora invites to join a club called C3. Sonora is a third year student and the President of the Club’s games called C3 based on the games of survival with Airsoft guns and BB guns. The other members of the Club include two daughters of second years called Hatsuse
Karila and Mutsu Honoka, and two other freshmen (Kirishima Rento, with families having a candy store and a very small girl Hinata Yachiyo) as Yura. Thus, we follow the lives of these students the day and amateurs of war games during their free time. What Yura ignores is that they are passionate about all compressed air weapons and survival games. The new recruit will then understand the meaning of the name of this club: Command, Control, Communication. Yura wonders if she will be able to integrate the group while remaining itself?
