Asuka R. Baggio directs the Museum of Water Guides in Neo-Venezia, embodying her profound connection to the history and traditions of the undine profession. She is a legendary veteran undine whose active years significantly shaped the Himeya Company's legacy. Her career established her seniority to Akira E. Ferrari, and together they represent the lineage of successors to Himeya's historic founding gondola, a symbol of the company's heritage and the responsibilities carried by its chosen undines.

Asuka's background includes mentoring and shaping Himeya's traditions. As museum curator, she preserves and shares the cultural legacy of water guides, acting as a living link between past and present undine practices. She interacts with younger undines like Ai, Azusa, and Anya within this setting, providing context about Himeya's history and the significance of its artifacts.

The narrative positions her as part of Himeya's lineage concerning the founding gondola alongside Akira. Discussions surrounding the gondola's eventual retirement underscore Asuka's role in maintaining traditions while acknowledging the need for evolution within the undine profession. Her presence reinforces themes of mentorship and the respectful preservation of heritage, framing her as a foundational figure whose influence endures through Himeya's ongoing legacy.
