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...
Not only am I a commoner,
،لستُ من عامّة الناس فحسب
Ich bin nicht nur von schlichter Geburt,
Además de no ser noble,
tampoco tengo padre o madre.
Además de no ser noble,
Je n’ai ni père ni mère,
alors pour ce qui est de ma lignée…
Non solo non vengo da una famiglia nobile,
Além de não ser de 
uma família nobre,
Я мало того что простолюдин,
