Rengoku

煉獄

Rengoku is a mysterious kunoichi of the Kimon Clan, possessing a unique physique and a talent for self-surgery. She can sew replacement or additional body parts onto herself. She has four arms and displays a variety of stitch patterns across her body. Her arms extend to resemble spindly spider legs, and she is regarded as a monster by the local villagers.
She is obsessed with her brother to the point of incest. His death drove her onto a path of vengeance against Jubei, rather than focusing on collecting the Dragon Stone.
