Youjo Senki

A young girl engages in intense aerial battles with army mages, using bullets, spells, and bayonets from above muddy trenches. Known as the Devil of the Rhine, she is considered one of the Empire’s greatest soldiers. Within her mind, however, resides a former salaryman from Japan who once lived a quiet life. After waking in a war-torn world, he finds himself reborn as a poor, orphaned girl with only past-life memories to guide her. Driven by the need to survive, she is willing to take any path, even one lined with danger and violence.
