Inept with a sword, unable to ride a horse, and apathetic toward the empire he serves, Regis Aurick is a hopeless soldier who spends his days buried in books. Banished to the borderlands, he encounters a stirring young woman with red hair and ruby eyes. She is Fourth Princess Marie Quatre Argentina de Belgaria, known simply to Regis as Altina. “…Do you want to become my tactician or not?” Having sought him for his rumored strategic prowess, she aspires to reform an empire led by self-seeking nobles and driven to pointless wars, the legendary blade of an emperor, the Grand Tonnerre Quatre, at her hip. Continuously underestimated by her regiment, including her would-be tactician, the princess resolves to prove her worth beyond a shadow of a doubt—no matter the risk. Here is a tale of war, love, and politics, woven by the bookworm and the sword princess.

“There are plenty of ways to defeat a navy that has nothing but its strength going for it...” After going up against High Britannia’s newest weapons, the Empire’s Seventh Army is helplessly defeated. While Regis’s command allows them to barely avoid complete and total annihilation, the Empire remains in a terrible predicament—the only way to stop the enemy invasion is by severing their sea routes, but the Belgarian Navy is facing great difficulties from another new innovation known as the steam ship. And so, Altina’s army heads to Port Ciennbourg to salvage the naval front. But with only sailing ships at its disposal, does Belgaria really have the means to turn the tide?! Here is the sixth volume of a tale of war, love, and politics, woven by the bookworm and the sword princess.

Fourth Princess Altina has been chased from the imperial court and assigned to command a faraway unit on the border. If she wants to one day become empress, what she needs most is wisdom. “The Eve” recounts the first time she learns about the bibliophagic tactician who goes on to become her biggest ally. A young Felicia must uphold a deception of the grandest scale, taking on a new identity to live as her late brother. Find out her fate in “Auguste, the Silver Princess.” Finally, in “A Vow to the Morning Star,” Third Prince Bastian sets off with Elize—whose right to the High Britannian throne has been stolen from her—to write a new story. Here is a set of short tales from the popular military fantasy!

What will happen when the bibliophagic tactician Regis faces off against the strategy officer chosen by a queen? Led by Oswald, the High Britannian Army begins its march across Belgarian soil. Altina’s forces must lend their aid to the losing imperial army, but the Grand Duchy of Varden chooses this exact moment to attack Fort Volks. Regis proposes a plan to send Varden’s troops packing in a single night, but it comes at a cost: the treasured sword is put out of commission, and Belgarian casualties are continuing to pile up. Will they really be able to protect the Empire!? As the battle continues, an unexpected encounter reveals more about Regis’s past... Here is the fifth volume of a tale of war, love, and politics, woven by the bookworm and the sword princess.
