Saga of Tanya the Evil

The Empire is involved in a war against the Entente Alliance, and fighting a poorly executed delaying action in the northern theater. Second Lieutenant Tanya Degurechaff leads a small platoon of mages. But there's something unusual about this lieutenant... she's only nine years old!

The secret of Tanya's birth is revealed.

After her stunning success with her first mission, Tanya is assigned to test a new piece of technology: a highly unstable prototype calculation jewel. This jewel offers her unparalleled power, but just using it risks her life.

Tanya is now living life on easy street, as a highly-respected student at the military university. She's so highly respected, in fact, that one of the Empire's chief military planners asks her for her opinion on the course of the war.

Tanya's new battalion is off the ground and running, and it's time for them to do their first mission: fight back a massive invasion!

After her easy victory over Dakia, it's time for a more difficult mission: aiding the destruction of the Entente Alliance to the north.

The Empire is launching a seemingly foolish attack on the Entente Alliance in the middle of winter. They lack the supplies to successfully invade, but Tanya realizes that this attack is intended to distract from the real mission.

The war with the Entente Alliance is done, and it's back to the Rhine for Tanya and her forces. The Republic troops are highly trained and stronger than any she's faced before.

The last enemy on the continent is the Republic, and the Empire has come up with a bold plan to take them out. Of course, Tanya is sent to the forefront of this operation, and is forced to take on the entire Republic army by herself!

Tanya's mission is a success, and the Republic is surrounded and crippled. But on her way back, she runs into a group of allied mages lead by Anton Souix, whose one mission in life is to take down the Devil of the Rhine!

As Tanya’s battalion carries out their final mission, they are attacked by defensive forces. They launch a counterattack, and come out victorious. This seemingly ends the war – but Tanya soon realizes the celebration may be premature.

The victory celebration for the 203rd mage battalion has been cut short. Republican forces are still active on the Southern Continent. Generals Zettour and Rudersdorf decide to send Tanya and her battalion to eliminate the enemy once and for all.
