Spy Classroom, Vol. 10 (light novel) — Takemachi

To learn the truth about the Nostalgia Project, Lamplight sets their sights on the Lylat Kingdom, the country where it all began. Separated from the others and living a lonely double life, Erna and Annette diligently lay the groundwork for a revolution. Unfortunately, they've embarked on a mission so difficult, even the Inferno twins once failed to get it done. Lylat is known as “the land where revolutions die,” and that title is thanks to a world-class counterintelligence agent. The girls' resolve and values are put to the test. It's far too late to back down now!
