Saga of Tanya the Evil

On the front lines of the war, there is a little girl. Blond hair, blue eyes, and porcelain white skin, she commands her squad with lisping voice. Her name is Tanya Degurechaff. But in reality, she is one of Japan's most elite salary men, reborn as a little girl after angering a mysterious being who calls himself God. This little girl, who prioritizes efficiency and her own career over anything else, will become the most dangerous being amongst the sorcerers of the imperial army.

For having insulted God, an arrogant Japanese salaryman in the moment of his sudden death is sentenced to be reborn in an alternate universe similar to 1910's Europe, in an empire torn apart by countless wars with all nearby countries. The salaryman is reborn as Second Lieutenant Tanya Degurechaff of the Imperial Army, a 9-year-old soldier girl. Plus this, according to God's words, if she's not able to die a natural death or she refuses to have faith in Him, her soul will leave the circle and be sent to hell for the countless sins that Tanya has committed in her previous life. In search for an escape, Tanya decides to enter into the Empire's Mages Division, hoping to reach a high enough rank as fast as possible to remain far from the battlefield and in this way avoid the risk of being killed. Even if she's now forced to speak with a young girl's lisp, Tanya soon turns into a ruthless soldier who prioritizes efficiency and her own career over anything else.
