Tanya & Mary Sue

The Saga of Tanya the Evil" tells the story of a Japanese salaryman who is reborn as a young girl, Tanya Degurechaff, in an alternate version of World War I-era Europe, after angering a self-proclaimed god. His atheist views and dismissal of the deity, dubbed "Being X," lead to his reincarnation as a punishment, with the promise of hell if he dies naturally or rejects faith. Tanya, now a powerful mage, is determined to survive the brutal war and find a way to retire comfortably, constantly clashing with Being X's attempts to make her believe Tanya: Tanya is a magically gifted Mage in the Empire's military at just nine years of age, quickly rising through the ranks due to her tactical genius, deadly efficiency, and unrelenting ambition. Tanya is a very complex character. In her past life, Tanya described herself as someone with many complexes and that he was twisted. She has both superiority and inferiority complexes, which is shown by how she compared herself to real geniuses she couldn't compete with, while also desired to be above others.Tanya has a lot of sociopathic traits; cold, calculating, and often sees others as objects she can use to her advantage. This allowed her to rise rapidly through the ranks of her careers in both lives. Mary: Mary Sue or Mary Sioux is one of the main antagonists of the series. She is the sole daughter of Anson Sue and his wife, who hailed from the Unified States. When she was a citizen, she was a caring and loving girl. She loved her father very much. Though her father's death almost crushed her mom, she joined the US volunteer forces more for patriotism than taking revenge to the Imperial soldier who killed her father. After she identified her father's submachine gun in Tanya's hands, she became more vengeful and serious. Her hatred grows whenever she hears the name "Devil of the Rhine", leading to her becoming enraged, resulting in her exposing herself to danger.
