Kaoru Shiba (志葉 薫 Shiba Kaoru) is the true 18th head of the Shiba House, a position that Takeru was holding in her place. To distinguish her ranger designation from Takeru, she is referred to by her vassals and servants as Princess Shinken Red (姫シンケンレッド Hime Shinken Reddo). She later resigned as the head of the Shiba clan and adopted Takeru (despite being younger than him), making him the new head. Her mecha are the Shishi Origami and the Tora Origami and her Power Rangers Super Samurai counterpart is Lauren Shiba, Jayden Shiba's older sister and successor as the Red Samurai Ranger.
