Pasaran/Origin

Origin
Kesaran-pasaran originate from a myth in Eastern Japan, where children collect fluff (originally animal fur/hair) to make a ball. It becomes a pet that is supposed to give good luck. It is coloured with flour or face power and it also a way of 'feeding' it. It is more commonly known (in anime or otherwise) as a cute white fuzzball that floats around.

A myth is that a mother who had lost her whole family and her home in the war started creating kesaran-pasaran out of sheer loneliness and despair. She used fox and cat hair and powdered it, probably as her only source of comfort and replaced her family.
