Bushido: Yatsumata

It’s unclear if this huge snake is a priestess of Orochi warped by the Kami into its image or simply a monster from the jungles of Shimagamo. In battle Yatsumata moves with frightening speed and direction as if guided by an unseen hand. In combat each head can deliver a muscle wasting venom through foot long fangs as hard as iron, downing even the toughest warriors as they are reduced to a whimpering mess. Two heads leave the unholy beast with few natural blind spots, adding to its already strong survivability and resilience gifted by its speed and thick scales.
