Showing mercy to the enemy is a betrayal of one's own allies.
A hero of war, she is... A monster wearing the skin of a young girl. A young girl stands at the front lines of the battlefield. With blonde hair, blue eyes, and skin so pale it's almost translucent, she flies through the sky, ruthlessly shooting down her enemies. Commanding the army with the lisp of a child, her name is Tanya Degurechaff— But inside dwells an elite salaryman, reborn as a woman due to the whims of a god. As tensions rise between the great powers, a war breaks out by chance. In the vortex of destruction that eventually escalates into a "World War," Degurechaff, who values efficiency and her own career above all else, becomes the most dangerous existence among the Imperial mages.
