Does anyone know anything about the hashihime youkai?
Hashihime was once a woman whose husband was unfaithful, she died and turned into a youkai which kills couples out of jealousy.
She usually is seen near the bridge because the Japanese love making out having a date there. (kind of romantic, I suppose they think)
There's also is a theory that state that "it's a bridge because the word bridge sounds similar to love" (橋 Hashi and 愛し Aishi)
From that, it's said that if you speak good about other bridges or sing (a song/poem) about a women when you're crossing a bridge, you'd get cursed by the Hashihime.
After she killed her unfaithful husband, she killed all his family and relatives, then went off killing anyone that came by the bridge.
Because of that, she's also depicted as both a God and an Oni (A guardian god of the bridge and a human that became an Oni in her deep envy.)
They said that when she killed a man she took the form of a beautiful women, and when she killed a women, a handsome man.
Although she's told of frighteningly in the fables, she's depicted as a lovely women in the old songs that sing about her... So, Parsee...
