DnD Monster: the Harionago (Asian/Rokugan)
The Harionago, also known as hari onna , is a yokai that masquerades as a beautiful young woman with long hair. Walking on the streets, often at night, she smiles or laughs at a young man. If he makes the mistake of returning her smile or laughter, her pretense drops, and she reveals the hooks on her long hair, using them to tear him apart, draining his life and eating his remains when he has been rent limb from limb.
