The “fan” evokes the shape of a scallop shell, while the “dang” draws on the imagery of pearl ear pendants. “Xiao Fu” imbues the piece with the qualities of a lucky spirit. In the anime’s lore, it serves as the guardian spirit of the “Coastal Blessing Shrine”—legend has it that touching its scallop shell can bring good fortune. The seams where its body is assembled form “blessing patterns” that glow with a soft gray light during high and low tides, guiding sailors along the coastline. Though timid by nature, Xiao Fu is deeply caring; it often hides within the scallop shell, quietly observing humans from afar—and when danger looms, it instantly retracts into its protective shell.
