Hikaru Hitachiin (常陸院 光 Hitachiin Hikaru) is the elder of the identical Hitachiin twins and is in Class 1-A with his younger brother, Kaoru, and Haruhi Fujioka. Although he is considered the "leader twin," he is less mature than Kaoru when it comes to managing his emotions and dealing with others. He and Kaoru are both members recruited by Tamaki to be in the Host Club. Hikaru and his younger twin, Kaoru, are first introduced when Haruhi stumbles upon the Host Club. As the classmates of Haruhi, both Hitachiins are major rivals to Tamaki's romantic interest for the female Host, which causes a humorous amount of friction between the President and the twins. It has been shown that although their looks are identical, Hikaru's character differs greatly from that of Kaoru's, and he is more dependent on his brother than the reverse . The Hitachiin twins are categorized as the "Little Devil" types and as such, are perceived as mischievous troublemakers (though not malevolent). Their selling point in the Host Club is their "Forbidden Brotherly Love" package, which has them acting out twincestuous schticks for the entertainment of their female customers. When not seen in the typical Ouran Academy uniform, Hikaru prefers to wear outlandish designer clothing, but still dresses a bit different than Kaoru. His short and somewhat-messy hair is depicted as auburn. Hikaru's rose color is light blue. In Japanese culture, blue signifies loyalty. Hikaru is incredibly loyal to Kaoru, even to his own detriment in terms of personal growth. In reality, the blue rose does not exist in nature; but in art signifies attainment of the impossible. Hikaru's love for Haruhi is never actualized; she is unattainable as is his complete individuation from Kaoru during the series. As children, Hikaru and Kaoru are inseparable and dislike everyone with the exception of their personal maid, whom they adore. The cunning woman promises to play the "Which One is Hikaru? Game" with them until she gets it right because the twin toddlers say they will give the combination of a family safe it to her when she wins. During the night, the alarm sounds and the twins discover their playmate heading down a ladder with the family's riches. She has broken open their piggy bank to access the slip on which the combination is written and broken her promise to them, as well. Disappointed, they ask why and she replies that she simply can not tell them apart and perhaps no one ever will, implying that unless a person can identify them as unique individuals, that person is untrustworthy. This comment becomes a self-fulfilling mantra for them, keeping them isolated and stunted in social skills. The Hitachiin family cannot be described as a cohesive family unit, as they do not spend much time together. Both Hikaru and Kaoru often mention that their parents work a lot and, as a result, cannot be there for them. This leads them to rely and depend only each other, hence their somewhat self-isolating tendencies.
