The Saga of Tanya the Evil, Vol. 6 (Manga)

Extoled for her achievements in Dacia, Tanya makes her grand return to Norden! As the war escalates, so do the General Staff's expectations for the 203rd Aerial Mage Battalion (much to the young major's dismay). From a barrage of enemy formulas to communication mishaps with higher-ups, it looks like everyone in the world--be they enemies or allies--will stop at nothing to sabotage the former salaryman!
