The mission to liberate Grebeauvoir ends in success, settling the war against the formidable High Britannian Army. Now with more achievements to his name, Regis receives another proposal from Latrielle...but the tactician promptly refuses, unable to agree with the prince’s ideals. With no other options, Latrielle gives the order: Regis d’Aurick must be assassinated. Regis plots his escape with the Renard Pendu mercenary brigade, but will our tactician manage to reunite with Altina? And how does he intend to oppose the budding new emperor?! Here is the eleventh volume of a tale of war, love, and politics, woven by the bookworm and the sword princess.

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.

High Britannia and Langobarti have joined forces, and now the two nations’ troops occupy the fortified city of Grebeauvoir! At the request of Second Prince Latrielle, Regis joins the First Army in its campaign to recapture the stolen territory, devising a scheme that ultimately allows Third-Grade Combat Officer Jean Juris de Varèse to infiltrate the city. With the cooperation of a girl named Fel, it is the esteemed officer’s duty to meet the representative of the captive civilians. Will the conflict with High Britannia finally reach its conclusion? Here is the tenth 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!

“I’ll go to the capital. Even if nothing but darkness awaits me there!” Despite the odds, Princess Altina succeeds in capturing what was once considered to be an impregnable fortress. However, as the newly labeled “Marie Quatre’s Army” settles into their new base of operations, a letter arrives. It is a request from Second Prince Latrielle—an invitation for Altina to return to the capital to celebrate the day the nation was founded. The second prince is a considerable threat, especially given his complete authority over the Belgarian military, but the princess has no shortage of possible enemies. First-Grade Admin Officer Germain, First Prince Auguste, and the Vixen of the South are all in attendance, and a clash of sides seems almost certain. But have those dead set on obstructing Altina’s ambitions already made the first move...!? Here is the third volume of a tale of war, love, and politics, woven by the bookworm and the sword princess.

An impregnable fortress able to withstand ten thousand men lies before them. If they refuse to capture it... the princess is a traitor!? Through a duel with Black Knight Jerome, Princess Altina earns the respect of her regiment and becomes the recognized commander of Fort Sierck. But celebrations are cut short by a barbarian attack, and in their vanguard stands an infamous warrior known as the barbarian king. Thanks to the wit of their tactician, Regis, the army snatches victory. But when news of their achievement spreads to the capital, Altina’s brother, Second Prince Latrielle, issues an order to capture an untouchable fortress in the Grand Duchy of Varden. It is an unreasonable demand made to weaken the princess’s growing forces, but they have no choice—refusal would have them branded as traitors to the empire. Regis speaks up. He has a plan to succeed where no army has before. Here is the second volume of a tale of war, love, and politics, woven by the bookworm and the sword princess.

Enter Bastian, the third prince of the Belgarian Empire, soon to bear witness to why the war truly began! Thanks to Regis’s careful planning, the princess’s return to the capital—as well as her subsequent battle with the White Wolf Brigade—ends in her favor. Altina’s army breathes a sigh of relief upon their safe return, but once again that peace is short-lived. Out of seemingly nowhere, the Belgarian Empire is invaded by its neighboring powers. Colonel Oswald Coulthard leads a fleet of steamboats from High Britannia, and the Grand Duchy of Varden launches a surprise attack on Fort Volks! But what drove them to attack? And how exactly is Bastian, who has gone to High Britannia as a foreign exchange student, involved in the war? Here is a tale of war, love, and politics, woven by the bookworm and the sword princess.
