## Plot

Princess Principal is set in a fictional analogue of Britain called Albion. During the early 20th century, the Kingdom of Albion monopolized a mysterious substance called "Cavorite" to construct a fleet of heavily armed airships that made Albion the dominant power in the world. However, the proletariat of Albion grew angry at their country's ruling class for largely ignoring their plight, sparking the "London Revolution" in which the lower classes attempted to overthrow the royal family. Eventually, the two sides reached a stalemate, and a great wall was erected through the middle of London, splitting Albion into two nations: the Commonwealth and the Kingdom.
Several years later, the Commonwealth launches "Operation Changeling", a plan to replace the Kingdom's Princess Charlotte with Ange, a girl who bears a strong resemblance to her, in order to have a highly placed agent within the royal family. However, the Princess turns the plan on the spies, offering to work with the Commonwealth if Ange and her friends will help her become the Queen of the Kingdom. So begins the story as five girls, including the Princess herself, serve as undercover spies in the Kingdom working for the Commonwealth, while enrolled as students at the prestigious Queen's Mayfair school.

Her grandmother, the Queen, bears a very close resemblance to Queen Victoria in the latter part of her reign.

Dorothy approaches Morgan, who is in possession of the key, but is turned away by his bodyguards. Ange then goes over to the Princess to befriend her, while "accidentally" spilling a "drink" on her dress. While Princess waits for a new dress, Ange impersonates her to get the key from Morgan. However, Princess is already aware that Ange and Dorothy are spies, and offers to work with them if they help her become Queen of the Kingdom. Ange signals to her handlers to ring a nearby church bell if they accept Princess's terms. The Duke of Normandy realizes the key has been taken from Morgan and orders a search of everyone at the party.

Ange agrees to carry out her wish. Ange and Dorothy then receive a mission to board HMS Gloucester and recover stolen printing plates. They decide to use Princess as way to board the ship, though Beatrice protests her participation in the mission. However, Beatrice's voice becomes odd as she shouts, and she flees in embarrassment.

After school, Chise participates in spy missions with Ange, Dorothy, and Beatrice, though she feels insecure about the fact that her fighting skills aren't always needed. She also regularly reports to Lord Horikawa, who wants to know whether Princess' plan to become Queen will succeed so he knows whether to side with the Kingdom or the Commonwealth.
