In August 791 UC, following their transfer out of Kapche-Lanka, Reinhard von Müsel and Siegfried Kircheis are posted to the destroyer Hameln II, currently docked in Iserlohn Fortress, as its chief navigator and security officer respectively. While the captain of Hameln II is impressed of their achievements and welcomed them on board, the rest of the crew are less than enthusiastic, especially the enlisted ranks who view Reinhard's position as a blatant example of favouritism. They then decide to test Reinhard by pitting him with another young enlistee, Rolf Zaidel, on a spacewalk challenge. However, when Rolf lands himself into trouble during the spacewalk, Reinhard risks his life to save him, thus earning him the respect of the enlisted ranks.
