Saga of Tanya the Evil, Vol. 10 (light novel)

Time is not on the Empire’s side. It has become painfully clear that simply winning battles will not be enough to turn the tide of this war. Having no interest in sharing the fate of her country, Tanya immediately decides to do the only thing that makes sense—look for a new job! Of course, she’ll have to proceed with extreme caution, because her current employer isn’t some random company but the Imperial Army. As it happens, she isn’t the only one ready to do something drastic when push comes to shove...
Time and everything else are running out for the Empire. In fact, it’s already running on fumes. Before the last grain of sand falls from its hourglass, each person will have hard choice to make. Some will shut their eyes to the inevitable. Others will choose to reject catastrophe. But even if they’re doomed, there’s no point in going down quietly. Beneath her mask of patriotism, Tanya vows to do whatever it takes to avoid going down with the ship.
