Sion has a minor role in Carnival Phantasm. Together with Satsuki and Riesbyfe, they share a segment called "The Back Alley Alliance" when Riesbyfe ignores Satsuki and often Sion has to stop them by saying the phrase "All according to my calculations". It should be noted that Sion often says that everything was according to her calculations, even about the smallest things. She even pretends she knows about things she really does not know at all.
