In Neo Venezia, Akari, Aika, and Alice work tirelessly toward becoming full‑fledged Prima Undine, the city’s professional tour‑guide gondoliers. Over the course of their training they have developed their own distinct styles for guiding guests through the canals and canalside streets. Along the way they draw on the counsel of their seniors: Alicia of the Aria Company, who is patient and understanding; Akira of the Himeya Company, who is strict and proper; and Athena of the Orange Planet Company, who is clumsy yet caring. Will the girls be able to blend the advice of their mentors with the knowledge they have earned about Neo Venezia?
