Born out of a dish towel or kitchen rag which has seen too many years of use past its prime, the shirouneri looks like a ferocious, yet tiny cloth dragon.
Shirouneri flies through the air, chasing cleaning staff and servants, and attacking them by wrapping its slimy, mildewy body around their necks and heads, causing them to pass out from the stench. Occasionally, shirouneri have killed servants by strangulation, though usually they seem more interested in mischief than murder.
