An adolescent Siren, Iris, drags her friend Arius into a daredevil adventure on the very island where Alphonse Flügel was stranded until recently. Following a note Alphonse left behind, they come across the Nekoya door and enter the restaurant, and since they can only eat raw fish, the Master serves them fish carpaccio. Later, the Master prepares a helping of extra curry buns he has received from an acquaintance, which he shares with "Kuro" and Aletta. During the course of the meal, "Kuro" reflects on her usually lonely life and how much it was changed by her work at the Nekoya, and begins to open up to her co-workers by conversing with them verbally.
