Ikta is a brilliant, but lazy and unmotivated boy.  His childhood friend, a high-ranking daughter of a noble, offers him an easy position at a library if he can help he get the top score on a military exam.  But their lives take a sudden turn when the boat carrying them to the exam runs aground, and Ikta rescues a mysterious girl on board.  When she turns out to be a princess, and they all find themselves behind enemy lines, Ikta is going to start having to work hard for real...
Even if we're taken prisoner, 
our safety is assured, right?
حتّى لو تمّ أسرنا، سلامتنا
مضمونة، صحيح؟
Unsere Sicherheit als Kriegsgefangene
ist doch gewährleistet, oder?
Aunque nos tomen como prisioneros,
nuestra seguridad estará garantizada, ¿no?
Si nos toman como prisioneros,
garantizarán nuestra seguridad, ¿no?
L’ennemi nous épargnera
Se anche dovessero farci prigionieri, 
saremmo comunque al sicuro, no?
Sendo prisioneiros de guerra,
Если сдадимся, нам не будет ничего угрожать?
