The most genius cashier in the world. Actually, she is perhaps even more intelligent than Lyri and Pikaqi combined. She is a mixture of Albert Einstein and Richard Feynman, but female. She was known as Lieutenant Airy until 2022 when the other Captains retired, and Captain Ecstatic gave her the honourary rank of Captain (as Captain Buoyant had refused to do so because she was strict about enforcing Nature's rule that friendships having to end someday).
