In the early twentieth century, the unveiling of Cavorite enabled the creation of cutting‑edge armaments and pushed the nation into conflict. London is now split by a barricade, and the Kingdom together with the Commonwealth of Albion wage an invisible war where covert operations are the sole means to unbalance the foe. A cadre of girls from the esteemed Queen"s Mayfaire academy serves as clandestine agents for the Commonwealth.
Under Dorothy, a seasoned driver with an arresting presence, the team features Ange le Carré—a ruthless liar and marksman; Chise, a skilled samurai; and Beatrice, an expert in voice impersonation. They deploy their distinct talents to help the Commonwealth endure a bleak landscape of intrigue, enigma, and penetration. Amid the war"s gloom, their singular objective remains: to finish their assignment.
