The Saga of Tanya the Evil

The Saga of Tanya the Evil, known in Japan as Yōjo Senki (幼女戦記), is a Japanese light novel series written by Carlo Zen and illustrated by Shinobu Shinotsuki. It began serialization online in 2010, on the user-generated novel publishing website Arcadia. Enterbrain acquired the series in October 2013 and has published fourteen volumes by September 2023. A manga adaptation with art by Chika Tōjō began serialization in Kadokawa Shoten's Comp Ace magazine from April 2016.

The series focuses on a salaryman whose reincarnation as the titular character living in an alternate version of World War I leaves her to be trapped in an endless cycle of reincarnation. Willing to avoid being killed whilst dying of natural causes, Tanya must take it upon herself to don a bloodthirsty, sadist ego in hopes of joining the ranks of the Empire’s Mage Corps as part of her plan to become a seemingly indestructible foe.

An anime television series adaptation by NUT was broadcast on Japanese television from January to March 2017, and was licensed by Funimation, Crunchyroll and Medialink. Saga of Tanya the Evil: The Movie, a theatrical film taking place after the events of the anime series, was released in Japan in February 2019. A second season has been announced.

Plot
In 2013 of modern-era Tokyo, an unnamed atheist Japanese salaryman, in the moment of being murdered by a disgruntled subordinate whom he had fired due to poor performance at work, is confronted by an entity that declares itself to be God who condemns the salaryman for not having 'faith'. The salaryman disbelieves in its existence, criticises its various statements from his perspective as an atheist and mockingly terms it as 'Being X'. The entity decides to reincarnate the salaryman into a world where he would face sufficiently difficult circumstances to turn to Being X for help.

The salaryman is reborn as Tanya Degurechaff, an orphaned girl in an alternate universe's equivalent of Imperial Germany, known as the Empire, in which World War I has been delayed until the 1920s and where magic has been incorporated into the military. According to Being X, if Tanya either does not die a natural death or refuses to have faith in it, her soul will leave the cycle of reincarnation and will be sent to hell for the countless sins that Tanya has committed in her previous life. In search for an escape, Tanya decides to join the Empire's Mage Corps and fight in the war, 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 lips, Tanya soon turns into a ruthless soldier who prioritizes efficiency and her own career over anything else, even the lives of those beneath her, especially those that get on her bad side.

Empire

 * Tānya Degurechafu (Tānya fon Degurechafu) (ターニャ・フォン・デグレチャフ)
 * Tanya is a young blonde, blue-eyed girl who is the reincarnation of a cold-hearted, atheistic, and social-darwinistic Japanese salaryman (briefly voiced by Kōsuke Toriumi in Japanese, and Josh Grelle in English). She is a mage with magical powers that enable her to fly and fire explosive bullets from guns. Compared to others, Tanya has a high latent magical ability and is the only one capable of using an experimental Type-95 operation orb due to Being X's interference. She controls a battalion of elite mages whose main purpose is to overwhelm enemy forces while also remaining highly mobile and relatively small. Tanya is quite ruthless and intolerant of failings in others, much the same as in her previous life, and employs several extreme punishments and training methods. After she graduated from War College as one of the Twelve Knights, she was granted the title of von. By the end of the TV series her rank is major. At the end of the movie, she finally gets her dream job working with an office job in the rear for 2 months with a promotion to lieutenant colonel, much to her joy and triumphs against her hated enemy, Being X. But that joy was short-lived when she received a phone call from General Zettour, who informed her that he had put her proposal, titled "Unit Usage and Operational Maneuvers in the Current War" to use and organized a Kampfgruppe codenamed "Salamander", which consisted of infantry, armor, and artillery, gave her command of the special army and wanted to see her research in action by having her and the 203rd mage battalion return to the front lines once more, much to her shock and horror.

 * Vīkutōriya Ivuānovuna "Vīsha" Sereburyakōfu (ヴィクトーリヤ・イヴァーノヴナ・セレブリャコーフ (ヴィーシャ))
 * Viktoriya is a Second Lieutenant in the Imperial Army and serves under Tanya Degurechaff, and later becomes her adjutant. Different from other characters from the Empire, Viktoriya is a refugee from the Revolution of the Rus' Union and her family was originally a member of the Rus aristocracy. Having served under Tanya during the Battle of the Rhine, Viktoriya is more familiar with Tanya's true personality, to which she shows fear, but also respect. As a result of knowing Tanya, Viktoriya is more able to keep up with Tanya compared to her other soldiers. However, despite knowing Tanya's side character, Viktoriya seems to believe that Tanya actually cares for her subordinates and her harsh treatment of them, is to ultimately ensure their survival. In the manga, Viktoriya's "particular" point of view of Tanya's character, seems to have started when Viktoriya, during her first true battle, is saved by Tanya at the last second, who (to hide her enjoyment in killing the enemy soldiers) quoted General Robert E. Lee, saying to Viktoriya "It is well that war is so horrible, otherwise men would grow fond of it", starting the misunderstanding. Tanya is also shown to perceive Viktoriya as identical in appearance to their former secretary in 2013 Japan; whether or not Viktoriya is the reincarnation of Tanya's secretary has not been confirmed.

Legedonia

 * Anson Sue/Sioux (アンソン・スー)
 * He is the captain of the 5th Aerial Mage Wing. He has a daughter called Mary Sue. He is later promoted to the grade of Colonel after the death of his superior officer. In the anime, he is believed to have been killed in battle by Tanya, during the Battle of the Orse Fjord. Later it is revealed that he actually survived and had a vision of God ("Being X") who told him to kill the "Devil", granting him additional power. In order to achieve his objective, he accepted to be part of an Allied Kingdom mage special force, managing to corner Tanya and her battalion over the sea. However, though in the end, he almost succeeds in killing Tanya, even willing to blow himself up to kill her, through Viktoriya's intervention, Anson failed to kill her and eventually died in his own explosion.

 * Mary Sue/Sioux (メアリー・スー)
 * She is the only daughter of Anson Sue. After her father's death at the hands of Tanya, she becomes rather more vengeful and serious in nature. Her hatred grows when she hears the name "Devil of the Rhine," leading her to begin to rage and expose an uncontrollable side. Granted additional power by Being X, she becomes the counterbalance of the main protagonist of the series. In the original Web Novel, following the execution of several of her subordinates on a whim, as she perceived them as refusing to follow her into battle, Mary Sue is ultimately the subject of a mutiny and is executed by her own supporters, realizing the truth of Tanya and Being X in her final moments. Her name is a direct reference to the "Mary Sue" trope.

Writing for Anime News Network, Nick Creamer says Saga of Tanya the Evil is differentiated from the majority of isekai anime that have heroic otaku or everyday young men as their protagonists by having Tanya be evil. Creamer explicitly says "Tanya's crimes are our crimes", indicting the capitalist system that produced her past self as a ruthless salaryman, and the consequences thereof for her new self.
