"Nurarihyon is said to be the leader of the Hyakki Yakou (Hundred Demon Night Parade). In the original tales, he is described as an old man with an elongated head, wearing fine clothes or the garbs of a head priest. He'll infiltrate mansions at dusk, while everyone is busy finishing up on chores for the day, and sit down in one of the rooms pretending to be the lord of the house: he will smoke the master's pipe, drink tea and sample the expensive food, bark orders at the servants and generally make himself at home. Sometimes he'll even dress up like a wealthy merchant and walk around town, or visit red light districts and mountain villas escorted by his youkai underlings. In Shigeru Mizuki's GeGeGe no Kitarou, Nurarihyon is one of the recurring antagonists of the series."
