Somehow ending up in the large castle that served as the Wings of the Magius’ headquarters, вы was disguised as a Black Feather, trying their best to find out where the leaders of the organization were. After a bit of wandering around, they end up finding a room with a large bed where they spot a girl coughing. It was Nemu Hiiragi, who could’ve been in a better condition than what she currently was in.
Upon seeing a Black Feather in the room with her, Nemu Hiiragi thought it was a perfect coincidence that she was thinking about having a Black Feather do something for them. “Excuse me, you over there. I need you to do a favor for me.” Nemu Hiiragi says. “There’s an Uwasa I need you to seek out…” The particular one she had in mind was the Uwasa of the Eternal Sakura.
