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!

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...

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...!!

When the average Japanese salaryman is suddenly thrown into in a world wracked with warfare and hardship by a supernatural power, they might first think to hide or run away. But not Tanya Degurechaff. A calculating and utilitarian man has been reborn as a child soldier. This young girl will do anything to rise in rank and find a way to live a life of comfort, and woe to any king, country, or god who stands in her way.

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?

As Holo and Lawrence begin the final leg of their journey, Lawrence decides to accompany Holo to her ancient home of Yoitsu, if only to forestall their parting just a bit longer. Boarding a ship from the port of Lenos (much to the chagrin of the wisewolf, who is none too fond of water!), the pair's fate becomes entangled with that of a boy named Col, whose tale of his circumstances - combined with the gossip of the sailors - leads to a shocking revelation about Holo's homeland!

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!
