The Serpent was a very mysterious clan leader. She conducted all her meetings from behind a gauze or shoji screen. Few knew that she was a hengeyokai. She was also a minor-ranked member of the Black Mist yakuza gang. She walked freely through public, confident that nobody knew her true appearance.
It was known that the Serpent was physically powerful, strong-willed, merciless, and capricious. She also loved dogs.
