Lauren Shiba is Jayden Shiba's older sister and the true 18th head of the Shiba Clan. As such, she took over the role of Samurai Ranger Fire, the Red Samurai Ranger and led the team against the Nighlok, being the only one who could seal Master Xandred away. Lauren and Jayden were separated at a very young age. Lauren was sent away in an attempt to fool the Nighlok into thinking Jayden was the true head of the Shiba Clan in order to protect her as she was able to perfect the Sealing Symbol.
