First off, her and her sister represent an aesthetic principle of japanese culture, that ephemerality makes things beautiful.(interestingly enough, it's the opposite in western though)
She is also very aesthetically striking herself, she has a very sleek design that combines a few different elements.
Her ability is also interesting in that sense, she is able to prevent change, but does that also preserve the beauty of an object? does that make its beauty vanish? does its beauty get enriched by that?
