Oni Gozen is a Japanese term that refers to a type of demon or monster in their mythology. These demons are usually described as being very scary and powerful, with big sharp teeth and wild hair. People in Japan used to believe that Oni Gozen would come out at night and cause trouble or harm to anyone who crossed their path.
The story goes that Oni Gozen was originally a beautiful and kind woman, but she became possessed by a demon and transformed into a monster. Some versions of the story say that she was cursed because she was too vain or prideful, while others say that she was tricked by the demon into thinking she was doing something good.
Today, Oni Gozen is often depicted in Japanese art and folklore as a creepy creature with a sinister grin and menacing eyes. Sometimes, they are shown carrying huge weapons like swords or pitchforks. While they are still considered frightening and dangerous, people these days mostly see Oni Gozen as playful and harmless characters in stories or video games.
