Den Rensman is the older brother of Elizabeth Rensman and the red ranger of the team. Den doesn't think of himself as a leader, he just mostly calls the shots. Den is always "FIRED UP!" and has a honest but funny personality. When he met Sho-Yun the lion man he wanted to be strong enough to protect everyone. But Den learned to protect people you sometimes have to go wild. In a special episode, Chase and Den learned the clothes changing jutsu, but when their dead foes came back they used their skill to make the Fashion Shuriken. "CHANGE TECHNIQUE! RED! SPIRIT! NINJAAA RANGER!"
