An older woman, Amarantha, requests a tour from Akari, who stays up late planning her route. At next morning's practice, Aika suggests the commission is suspicious, and Alice speculates it's an inspector from the Gondola Association. When Amarantha arrives, she requests Akari show her the Neo-Venezia that only she can. Aika and Alice follow them secretly. Akari takes Amarantha to a spot where a statue appears to cradle the floating climate-control island, and the woman shows her an even better vantage where two statues seem to hold it up together. Throughout the tour, Amarantha is shown knowing more about the city than Akari, and when Akari ends it by taking her to an abandoned monastery garden that ran wild after the water rose, Amarantha has Akari go through a door that leads to another flooded courtyard covered by a wisteria in bloom. Akari is disappointed to learn that Amarantha already knew everything she's been shown, but Amarantha thanks her for a tour that showed the Neo-Venezia she loves. Aika and Alice are discovered, and Alicia tells the trainees that Amarantha likes to test Singles, and once tested herself, Akira, and Athena as Singles.
