Die Wacht am Rhein II (ラインの護りII) is the forth chapter of Youjo Senki Manga.
Tanya takes her squadron for a 'walk' on the Rhine front to know each other better, which involved a lot of dirt, blood and iron. Visha received her baptism of fire on the Rhine Front, even more so as she was assigned to be wing pair with Tanya. The two volunteers of her squadron were reassigned shortly after for mutinous reactions and died honorably.
Shortly after there is an emergency report that artillery observer mages were pinned down by the vanguard mages of a large Republic offensive. As the 205th responds to the call, Visha volunteers to go on the mission contrary to Tanya's opinion on her state.
