Nejimaki Seirei Senki: Tenkyou no Alderamin

A conflict exists between the Katjvarna Empire and the Kioka Republic, with Katjvarna defending its borders. Yatorishino, a member of a prominent imperial family, is preparing for high-ranking officer exams. To secure a top position, she enlists Ikuta, a disinterested and pacifist individual with a tendency to chase women, to take the exams alongside her in exchange for a favor from her family. The initial written exam proceeds smoothly, and they travel by boat for the next stage. However, the vessel is lost, leaving Yatorishino, Ikuta, several other candidates, and an enigmatic, significant young girl stranded in enemy territory.
