Kaoru Hitachiin

Kaoru Hitachiin is the younger of the Hitachiin identical twins. He and his older twin, Hikaru, are introduced when Haruhi stumbles upon the Host Club. Being in the same class as she is, they are rivals against Tamaki Suoh for Haruhi's romantic attention. Kaoru is just as playful as his identical brother, but is a more insightful and easy-going person. He is also the first of the two to understand that their co-dependence must end if they are to develop into separate and whole individuals.As members of the Host Club, Kaoru and Hikaru are the "Little Devil" types, as they are mischievous (though not malevolent) troublemakers. They are famous for their "Forbidden Brotherly Love" package, carrying out twin-cestuous schticks for the entertainment of their female customers. A favorite game of theirs is the "Which One Is Hikaru? Game," in which they cover their hair with matching caps and ask people to identify Hikaru. No one except for Haruhi has guessed correctly, with logical reasons for doing so. Due to this, and the fact that she sees them as unique individuals, both brothers develop romantic feelings for her. Though each brother takes her on a date, only Hikaru's is shown in Ep 16 - Operation Haruhi and Hikaru's First Date! Kaoru and Hikaru are both wealthy and playful; however, Kaoru is the calmer and more mature of the two. When apart from his elder brother, Kaoru becomes a pleasant person, acting in a selfless and serious manner, but when he is with his elder twin, he reverts to being a scamp-like individual. Although the twins have spent the majority of their lives interacting only with one another, Kaoru demonstrates an understanding about social interactions and innate self-control. Kaoru is born under the star-sign of Gemini, the Twins. The positive traits of this sign are adaptability, versatility, enthusiasm, eloquence, wit and intellectualism; the negative traits being inconsistency, superficiality, indecisiveness, lack of focus and nervousness.
