Known as Hari onna (hook woman or hook girl)
A fearsome yokai known as hari onago appears at night on the roads of Shikoku, and is indistinguishable in the dark from an ordinary young woman with loose and disheveled hair. Upon closer look, however, the tip of each of her hairs is fitted with a needle-like, barbed hook – though if one is close enough to notice these hooks, it is probably already too late.
Hari onago wanders the streets searching for victims – usually young, single men walking by themselves. When she comes across a suitable man, she smiles coyly at him. If the smile is returned, she attacks: she lets all of her hair down, and the barbed ends lash out with blinding speed and a will of their own, sinking deep into her victim’s flesh. Her strength is so great that even the strongest man can be overpowered by her hooks. Once her victim is ensnared and rendered helpless, she rips him into pieces with her hooks and devours the remains.
It is technically possible for a very fast runner to escape a hari onago, providing his home is close enough and has a sturdy door or gate. If he can get himself safely indoors before her hooks catch him, he may be able to survive until sunrise, when these yokai vanish. The scars and gouges she leaves in the wooden door frame remain as a testament to her viciousness, and as a cautionary tale to young men not to pick up strange girls.
so if you saw a girl that has a long hair and it is smiling at you at night, can you smile back?
