Hikaru Hitachiin is the elder of the Hitachiin twins and is in Class 1-A with his younger twin, Kaoru, and fellow Host Club member, 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.
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. A common game they love to play is the "Which One Is Hikaru? Game", which involves the twins disguising their hair with identical caps and then asking people to guess which one is Hikaru. Only Haruhi gets it correct, with logical reasons for her doing so. Her ability to see them as unique individuals is one of the reasons they both develop romantic feelings for her, which results in the twins taking her out on separate dates (though the anime only shows Hikaru's).
Because of his immaturity in dealing with others, Hikaru is childishly over-possessive of each club member. An example of this occurs during Ep 16 - Operation Haruhi and Hikaru's First Date! wherein Hikaru becomes jealous of Haruhi's childhood friend, Arai. Haruhi slaps him when he becomes rude, and he runs away with Kaoru chasing after. Another example of this is in the manga, when Hikaru becomes annoyed at Haruhi's constant chatter about Tamaki and his family situation. He storms off yet again, with Kaoru following once more. In the end, it is Kaoru who helps Hikaru understand his romantic feelings for Haruhi despite his own.
Hikaru 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. There is speculation about whether Hikaru and Kaoru each possess all traits or if the traits are split between them to create a "good" twin and an "evil" twin.
AppearanceWhen 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. At a point in the manga, he dyes his hair dark brown to differentiate himself from his twin, Kaoru. In the anime, he is shown to dye his hair pink in order to differentiate himself from his twin after a fight, and later alters it to powder blue to confuse the female customers in the Host Club (though Haruhi saw through their trickery).
Hikaru tends to part his hair to the right, while Karou parts his to the left. Although they tell Tamaki that they switch it on a daily basis, the parting of their hair is generally consistent, unless they are deliberately attempting to confuse others. Both twins possess amber-colored eyes, a thin face and pale skin. In many cases, the older twin stands on the right side, which Hikaru does.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. The pastel nature of the color reflects a less intense affect on the character, as in a child or adolescent.
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'll 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's 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't 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.Because of their long-standing co-dependency, the twins lack the ability to interact properly with others. During grade school, this manifests itself in their refusal to interact with anyone unless that person can tell the two apart; however, no one can. Their disappointment and hurt is kept inside, furthering their isolation and perverting their psyches until Tamaki Suoh invites them to join the Host Club. Though uninterested, they ask him to play their who-is-who game to amuse themselves; Tamaki accepts on the condition that if he wins, they must join his club. Though he initially loses and is ridiculed by the twins who've discovered that he's the illegitimate son of Ouran's Chairman of the Board, Tamaki persists. He wins with intuition, which the twins refute; but his willingness to accept them as they are, their faults as admissible as their assets, impress them as nothing had since the day their maid declared their symmetry something to be feared and they agree to give the Host Club a chance.
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.
Mr. Hitachiin (The Hitachiin Patriarch)Hikaru's father, whose name is unknown but who adopts his famous wife's surname, runs a computer software company. He appears to be a more down-to-earth person than his spouse and sons and is often hidden in the shadows, appearing invisible to everyone else around him (including his family); at one point, Haruhi even mistakes him for Yuzuha's escort. The Hitachiin patriarch is also noted to be one of the few people who can consistently tell the twins apart, even if their backs are turned to him. Although he doesn't show his emotions easily, it is evident that he cares much more for his children than he lets on and gives good advice when necessary.
The little-seen younger sister of Hikaru, Ageha is a manga-only character. Although the twins dote on her and give her dresses and toys, she is unimpressed by them and frankly rejects their presents to their faces.
Tamaki is one of the first people to actively seek to break through the isolation that he sees in the twins by inviting them to join his newly formed Host Club while the twins are still in middle school, using intution to guess their correct identities and foiling the twins' plans to reject his offer. Though both Hitachiins find him initially annoying and troublesome, they grow to admire Tamaki because of his ability to see them both as unique individuals and an inseparable unit, simultaneously, which he views as a positive. In fact, it is Tamaki who suggests that they use their identical looks to develop the "Forbidden Brotherly Love" package.Hikaru, like his brother Kaoru, frequently plays jokes on Tamaki and finds it especially amusing to tease the Host Club President over his desire to be called "King" (aka Tono/Boss) and, instead, calls him an idiot. Knowing that Tamaki loves Haruhi, even if he's unaware of it, both twins flirt with her endlessly to prod him into reality or just to get him fired up for their amusement. An example of this is seen in Ep 07 - Jungle Pool SOS! when they trick the blond into a water gun fight by telling Haruhi they're going to marry her and go on honeymoon which effectively gets Tamaki into the fray. Despite being frequently exasperated by them and calling them "shady twins," he genuinely seeks their welfare.
megane character in Ouran, though very different from Kyoya. He's best known for his antics in Ep 21 - Until the Day it Becomes a Pumpkin!, wherein Class 1A prepares a Halloween frightfest and the twins overhear that Kazukiyo is a 'fraidy cat. They band with him and Haruhi as Team B, prankinig him relentlessly until they see what they think is the Clocktower Witch. In Volume 13 of the manga, Kazukiyo and Kaoru share a room together during the class ski trip, and Hikaru ends up joining them on the second night when rooming with Haruhi becomes too awkward. The following day Hikaru forces Kazukiyo to ski down an expert slope and Kazukiyo twists his ankle, forcing Hikaru to piggyback him to safety. He is later seen at the Hitachiins' New Year's Eve party, assuring a group of girls that his leg is healing fine. When Haruhi announces in Chapter 83 of the manga that she's leaving to study abroad for a year, Kazukiyo panics that the twins' pranks on him will increase without her mitigating influence. When Kazukiyo admits his feelings to Momoka in college, Haruhi and the twins are shown in the background cheering him on.
