In a land similar to WW1 Europe, war is on the horizon. With her high magic aptitude being acknowledged by her carers and scientists of the empire at a young age, nine-year-old Tanya Degurechaff is quickly recruited into the Empire’s military, becoming (a loli) one of the youngest soldiers in its ranks. Tanya’s fighting powers and military brain is nothing to joke about, and with these two attributes, she quickly climbs the ranks in the military. However, my audience, sensei and I are here to tell you the reason for this: She is a reincarnation of an modern japanese salaryman, who is someone you wouldn’t bring home to your parents. He was pushed into the path of an in-coming train by the co-worker he helped laid off and just before the impact; he starting blaming this event of the supidity of god. Suddenly time stopped, a being claiming to being god (dubbed being X by our MC) challenged his views and set a out to turn our atheistic salaryman into a thesist. Being X did this by putting our MC soul’s inside a little girl, so our MC set out to plot his revenge on Being X.
