Kaoru Shiba

'"Shinken Red!~Shiba Kaoru!"

"This brings a chapter to an end!"

- Kaoru after a victory in battle

Kaoru Shiba (志葉 薫) is Shinken Red (シンケンレッド) of the Shinkengers. She is the true 18th head of the Shiba House, a position that Takeru was holding in her place. She is referred to by her vassals and servants as Princess (姫). She is also identified as Princess Shinken Red (姫シンケンレッド) to distinguish her from Takeru. =Biography==

Shinkenger
As the 17-year-old head of the Shiba House, Kaoru is the one who possesses the knowledge of sealing the Gedoushu. Due to this, she stayed in hiding while Takeru acted as her kagemusha to keep the Gedoushu away from her. However, refusing to hide, and perfecting the sealing character, Kaoru takes back her title and assumes her birthright.

Even though it could be hinted that her appearance would open up a ridge between Takeru and the other Shinkengers (especially seen as how Takeru's childhood friend Genta appeared to dislike her at first), they stood loyal neither to the Shinken Red figure, nor to the figure of the head of the Shiba house, but to Takeru as a person, which Kaoru understood and accepted, eventually adopting him to make him her legitimate successor as the head of the Shiba clan. (i.e. She became his adoptive mother even though she is younger than him)

Like Takeru, Kaoru has the ability to become Shinken Red and can use the Inromaru to transform into Super Shinken Red.
