シュヴァルツェスマーケン 隻影のベルンハルト

Jürgen Bernhardt fights the BETA a decade before his sister Irisdina takes command of East Germany's 666th TSF Squadron. The alien invaders have already pushed west across Eurasia, and the German Democratic Republic answers with Tactical Surface Fighters while the Stasi watches every unit from behind. This light novel side story follows the younger Bernhardt through those earlier war years, filling in family history that the main Schwarzesmarken narrative treats as settled background.
