After concluding their talks with Crusch, Subaru and Emilia return to the village of Arlam, intending to report to Roswaal and discuss what to do next. But they find Arlam deserted and learn that the villagers who had taken refuge in the Sanctuary with Ram have not yet returned. When Subaru and Emilia arrive back at Roswaal's mansion to find out where the Sanctuary is, they are greeted by Frederica, a young woman who used to work as one of Roswaal's maids.
