S02E20 - The Shadowless Guests...
Synopsis
During a summer heatwave, Akari sees a lady in a black dress and veil near Piazza San Marco. While waiting for Alice, Aika tells Akari a Manhome ghost story about an executed Venetian woman who spirited away gondoliers who rowed her to the cemetery of Isola di San Michele, where she was refused burial, with the conclusion that she has been seen in Neo-Venezia. That evening, the lady in black politely asks Akari for a ride to Neo-Venezia's recreation of San Michele, and Akari agrees to take her as a friend. As they cross the bay, they are watched by dozens of cats from the rooftops. When they arrive, the lady drags Akari into the cemetery, saying she wants to keep her "friend" with her forever. Her veil blows off, revealing an empty dress, and in a gust of wind Cait Sith appears behind her. The dress runs away, and Cait Sith embraces Akari, who then she wakes up at Aria Company holding a rose petal from the cemetery. The next day, Alice explains that the ghost story is not from Manhome but was invented on Aqua—which makes the black lady even more scary.
