At last, the silver-tongued Tanya manages to thwart plans for a winter offensive and secures a path to the rear—not. Instead, an imperial order launches the dumbfounded Degurechaff into the freezing war abyss, where no amount of cursing can absolve her from her new duty. But just as White Silver begins to lose trust in the Empire, and unexpected ray of hope shines down upon her. Could things finally be looking up for the young major?!

The eastern front is a place where soldiers never sleep and artillery guns howl without rest. This quagmire is where the Salamander Kampfgruppe has been hurled once again, just another cog in the grand war machine of their fatherland. Still, there's only so much one unit can do. As the fighting ramps up with renewed enemy attacks and a brand-new weapon that pitches the Federation's quantity against the Empire's quality, Tanya faces one of her toughest battles yet, making a certain visitor's arrival a sight for sore eyes...

At last, the long-awaited days of tranquility are here! Tanya begins attending war college, where she spends her time feasting in leisure. But who would've thought that a conversation with General von Zettour would lead to another turn of events...! Will her days of delicious bread and clean bed sheets come to an end?

When the Republican Army, led by Lieutenant Colonel Vianto, attacks the imperial supply base of Arene, the Empire’s top brass orders the 203rd to carry out an operation that Tanya herself proposed back in war college—the “Devil’s Protocol.” But what exactly are the fearsome contents of this ominously named plan...?

As hinted at by Colonel Lergen's "thoughtful" words of advice, an attack on Dacia has been ordered by the Empire, and the fearsome power of the new mage battalion is deployed. Determined to unleash the power of modernity upon the enemy, Tanya prepares her freshly polished human shields for an all-out battle...There's no holding back with a resume-worthy achievement on the line...!!

Only a step away from their demise, the Regadonia Entente Alliance desperately push for a government-in-exile. Meanwhile, the notorious “Rusted Silver” Tanya von Degurechaff faces off against Colonel Anson Sue in another fatal battle that threatens to change the course of the entire war...and her chances of promotion!

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!
