Tearmoon Empire (Manga) Volume 3 - Nozomu Mochitsuki

With the school dance finished (and with only a moderate number of injuries and kidnappings having occurred over the course of it), Mia's stay at Saint-Noel Academy has finally begun in earnest! That's right--it's time for her to sit back, relax, and enjoy a luxurious and leisurely school life filled with... Wait, what do you mean, lessons? \nIndeed, not even the children of nobility can escape the myriad horrors of schoolwork. Fortunately for Mia, she's been through all of this once before! Unfortunately for Mia, her memory is, shall we say, not her strongest asset. But hey--Mia's survived worse, and compared to saving an empire from imminent doom, tricking her classmates into thinking she's academically gifted should be a cakewalk! Besides, it's not like she'll have any conspirators to punish, connections to forge, or charming princes to woo in the meantime...right?\n
