While training in a strait with difficult currents, Akari and Aika witness the impressive rowing skills of a younger girl, Alice. She bluntly refuses their attempts at friendship, but is troubled by Akari's sincere smile, which is unlike those of other undines. The next day, Alice meets Akari and Akatsuki, an apprentice salamander (weather controller), and joins them first on Akari's gondola tour of Neo-Venezia, then on Akatsuki's tour of the floating weather station where he lives, becoming friends with Akari in the process.
