Toushi no Aibou.

In the age of Tartaria, science was the only wall between humanity and the abyss. But when an ancient, mystical relic surfaces, that wall shatters. What starts as a mere technological glitch rapidly spirals into a war that threatens to consume everything. Caught in the eye of the storm is a brilliant princess, a girl whose obsession with the unknown makes her the kingdom’s greatest asset—and its biggest target. Thrown from the safety of her palace into a brutal front line where steel clashes with impossible horrors, she’s forced to master the art of war on the fly. Amidst the smoke and the chaos, she discovers a connection that will shift her fate forever. As the world teeters on the brink, the question isn’t just whether her intellect can save the Ten Realms—is it possible that the dangerous attraction she finds in the shadow of war will be the thing that finally breaks her?In the age of Tartaria, science was the only wall between humanity and the abyss.
