Now thought to have been assassinated at the second prince’s order, Regis returns to Verseilles in disguise. There, he unites with an unexpected ally, enacting a plan to sow political discord. In the midst of this covert operation, Altina leads her army to the capital where she at last reunites with her tactician. There is no time to rejoice, however—tensions linger, and a new emperor soon takes the throne. Latrielle issues a declaration of war to all surrounding nations, and Altina is dispatched to the disastrous southern front. Here is the twelfth 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.

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!

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.

“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.
