On the front line of the war, there’s a little girl. Blond hair, blue eyes and porcelain white skin, she commands the army with lisping voice. Her name is Tanya Degurechaff. But in reality, she is one of Japan’s most elite salarymen, reborn as a little girl after angering a mysterious being X who calls himself “God.” And this little girl, who prioritize over anything else efficiency and her own career, will become the most dangerous being amongst the sorcerers of the imperial army… The Youjo Senki Manga is the manga adaption of Youjo Senki light novel series. It is written by Carlo Zen, illustrated by Chika Tōjō and published by Kadokawa.
Though the anime follows closely to the original source, it markedly highlights the brutal and cruel side of Tanya’s character. This could be seen from a number of differences in her monologue and action. In the first episode, Tanya purposely arranged the death of two insubordinate soldiers under her, while in the original source they were simply taken off of her platoon to prevent discord. She also behaves colder and distant towards Visha; as opposed to being delighted by her help during the recruitment period of the new mage battalion, she wishes she could have left Visha in the Rhine instead.
