Tanya Degurechaff is the most important character. She is a reincarnated salaryman in a girl's body in a military - focused world. She is highly intelligent and ambitious in the military.
The theme of identity is present as well. Tanya, with her reincarnation into this new world, has to deal with her new identity and how it affects her place in society and the military.
The main character is Tanya Degurechaff. She is a young girl who is actually a reincarnation of a salaryman from Japan. There are also other important characters like Colonel Viktoriya Ivanovna Serebryakov who is Tanya's superior in the military.
The moral and ethical questions raised in the Saga of Tanya the Evil are thought - provoking. Tanya is often in situations where she has to make tough choices. Is she a hero or a villain?
