The Slit Mouthed Woman

There is a legend in Tokyo about a woman who was married to a man who was abusive and jealous. One night he was super drunk,and this time the woman tried to fight back unfortunately she failed and as a consequence, the man took a knife and carved a smile in her face. She died that night. Now as the locals say she walks the earth. A woman has told me she wears a trench coat, long black hair,and green eyes. She also wears a doctors mask to cover up her scars. I am here in Tokyo to see if the legend is true.
