Near the end of summer, Alicia (assisted by Akari) gives a tour to an older couple celebrating their wedding anniversary. The husband turns down his wife's suggestion of visiting Piazza San Marco after lunch and orders her to meet him at the harbor later in the afternoon. Later, Akari, Aika, and Alice meet him having an argument with a man who won't rent him the bucintoro boat for the "Marriage of the Sea" ceremony (performed in Neo-Venezia by the mayor instead of the Doge of Venice), which his wife has long wished to see. Akari offers to help the couple, using her gondola as a substitute, and the three trainees decorate it to the best of their abilities. Aika finds a volunteer band to play the music, and as they start the ceremony, Alicia, Akira, and Athena's customers ask to watch. Because the husband forgets to bring the ring, they use one bought by the wife that afternoon. During the ceremony, the wife calls their recreation clumsy but thanks her husband for the gesture, and when the ceremony is over she asks him to love her forever.
