A yokai depicted by Toriyama Sekien in his Hyakki Tsurezurebukuro. It takes the form of a tattered cloth billowing like a dragon in the wind; Sekien glosses it as “an old wiping cloth that has transformed.” The name is thought to pun on “Shirōururi,” a figure from Essays in Idleness (Tsurezuregusa). It is generally understood as a tsukumogami created by Sekien’s design. The work does not detail specific harms or behavior, and later interpretations often add their own ideas.
