The mailman's gondola is being repaired, so just for today, Akari is making the rounds with him to get the job done. As she learns the ins and outs of what it means to be a mail carrier, she meets a boy who needs his letter delivered at any cost. Whatever the envelope he's holding contains, it's very close to his heart.

Another wonderful holiday has arrived: Festa Del Bocolo! This day is a celebration of an ages-old story on Manhome, about a knight whose love for his lady lived on after his death in the form of a rose. In Neo-Venezia, that means that women everywhere receive roses from the people who admire them. Akatsuki wants to give Alicia as many roses as he can, but he's too nervous to deliver them (even though he'd never admit it). Will Akari be able to help?

Summer is blazing in Neo-Venezia. The days are so hot that Akari is starting to see things... One minute, she's walking down a crowded street, and the next, everyone is gone. Following President Aria in a haze, Akari wanders into a mysterious cafe, with a very unusual clientele... Later, the girls all decide to buy Nightshine Chimes, delicate little wind chimes with a glowing bead inside. The glow only lasts for a month before it fades, so Akari decides to make the most of the time she has.

When Akari takes her gondola in for a routine inspection, she's given some startling news - the repairman tells her that the gondola is now too old and worn for tourism use, and should be sold off for hauling cargo. Although she at first resists, Akari knows that the repairman is right; so she decides to travel with her gondola to all the wonderful places that she's been, as a way of saying goodbye.

The whole town is sizzling in a strong summer heat wave, and the girls are doing the best they can to beat the heat. But then, Akari spots a woman dressed all in black, with even her face covered with a thick black veil. Aika tells Akari a Manhome legend about the spirit of a woman dressed in black, who was angered that she couldn't be buried on San Michele Island. Supposedly the ghost spirits away any gondolier foolish enough to take her on board... but that's only an old story, right?

Heavy rain keeps the girls from their usual gondola practice, so instead they spend the day at Himeya. They start off studying at first, but when their minds drift off to what nicknames they'll take as Primas, Akira steps in and gives them some good old-fashioned paperwork to do. Even that can't get Aika down, however... because she's noticed lately that people whisper to each other when she walks past. Does that mean she's finally being recognized for her skills as an Undine?
