Her Majesty’s Swarm

Our protagonist is a college student who enjoys playing as the evil-aligned faction Arachnea in her favorite real-time strategy game. One day, she finds herself in a world similar to the one in the game; additionally, her body is now that of a fourteen-year-old girl. While things are a bit different from how they were in the game, one element has remained the same: she is the leader of the Arachnea. The insects under her control, collectively known as the Swarm, praise her and implore her to lead them to victory. In order to survive, she raises her Swarm and forms friendly relations with the elves of the neighboring forest. But after a slaver traveling through the forest murders one of her Swarm and the nearby kingdom's knights burn down the elven village and massacre its people, she prepares to launch her counterattacks in the name of revenge. However, revenge is merely a pretense for attacking the countries of this world. Her command is masterful and severe, as one who has played the game in real life...

After quickly conquering the great power of the north, the Kingdom of Maluk, Grevillea and the Arachnea prepare for their next war. They set their eyes on the Dukedom of Schtraut, a country of merchants northeast of their territory that will provide a shortcut to defeating the other nations. Accompanied an elite squad of her strongest units, Grevillea sneaks into the Dukedom and begins gathering information on the country’s topography, defenses, and culture. She and her group establish themselves as members of the local Adventurers’ Guild, and they begin hunting monsters to fulfill the guild’s quests. While they work to form connections, however, Grevillea secretly prepares to bare the Arachnea’s fangs against the Dukedom...

Grevillea, Queen of the Arachnea, has rapidly decimated the Kingdom of Maluk and now the Dukedom of Schtraut. After receiving troubling reports that the shores of her newly obtained territory are being raided, she investigates the matter. She discovers that these raiders are pirates under the command of a female captain named Isabelle. The pirates belong to a colony on the island of Atlantica, and they are a formidable faction not to be trifled with. Grevillea conspires with Isabelle and improves her navy. Strengthened by this partnership, she aims to plunge the Popedom of Frantz into the depths of despair...

After subjugating three countries, Grevillea sets her sights on her next target: the supreme military power and land of swooping wyverns, the Nyrnal Empire. In order to secure a path into the country, she must first seize the neighboring Eastern Trade Union. The Union’s capital city of Khalkha is a paradise where any and all pleasures are within arm’s reach—but when Grevillea and Emperor Maximilian vie for supremacy, will its utopian streets run red with blood? The Arachnea and the Empire, the two remaining great powers on the continent, clash for the right to rule. As Grevillea’s secrets are dragged out into the light, the story hurtles toward its climax!
