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 Hitachiin, and Haruhi Fujioka. Although he is considered the “ drawing card twin, ” he is less senesce 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 Ouran 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 measure 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 pendent on his buddy than the reverse. The Hitachiin twins are categorized as the “ little Devil ” types and as such, are perceived as arch troublemakers ( though not malevolent ). Their sell point in the Host Club is their “ Forbidden Brotherly Love ” software, which has them acting out twincestuous schticks for the entertainment of their female customers. A coarse game they love to play is the “ Which One Is Hikaru? Game “, which involves the twins disguising their hair’s-breadth with identical caps and then asking people to guess which one is Hikaru. merely Haruhi gets it chastise, with coherent reasons for her doing so. Her ability to see them as unique individuals is one of the reasons they both develop romanticist feelings for her, which results in the twins taking her out on separate dates ( though the zanzibar copal entirely shows Hikaru ‘s ). Because of his immaturity in dealing with others, Hikaru is childishly over-possessive of each club extremity. An model of this occurs during Ep 16 – process Haruhi and Hikaru ‘s First Date ! wherein Hikaru becomes jealous of Haruhi ‘s childhood supporter, Arai. Haruhi slaps him when he becomes ill-mannered, and he runs away with Kaoru chasing after. Another example of this is in the manga, when Hikaru becomes annoyed at Haruhi ‘s constant yak 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, exuberance, eloquence, wit and intellectualism ; the damaging traits being incompatibility, superficiality, indecisiveness, miss of focus and nervousness. There is meditation about whether Hikaru and Kaoru each posse all traits or if the traits are split between them to create a “ commodity ” duplicate and an “ evil ” match .


When not seen in the typical Ouran Academy consistent, Hikaru prefers to wear bizarre designer invest, but however dresses a moment different than Kaoru. His unretentive and somewhat-messy hair’s-breadth is depicted as auburn. At a steer in the manga, he dyes his hair darkness brown university to differentiate himself from his gemini, Kaoru. In the anime, he is shown to dye his hair pink in arrange to differentiate himself from his twin after a fight, and late 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 leave. Although they tell Tamaki that they switch it on a daily basis, the part of their hair’s-breadth is generally consistent, unless they are intentionally attempting to confuse others. Both twins possess amber-colored eyes, a thinly face and pale skin. In many cases, the older twin stands on the right side, which Hikaru does .
Hikaru ‘s rose color is lightly aristocratic. In japanese culture, blue signifies loyalty. Hikaru is fabulously firm 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 unachievable as is his complete individuality from Kaoru during the series. The pastel nature of the color reflects a less acute 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 charwoman 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 clock sounds and the twins discover their playmate heading down a run with the family ‘s riches. She has broken open their piglet bank to access the strip on which the combination is written and broken her promise to them, adenine well. Disappointed, they ask why and she replies that she simply can not tell them apart and possibly no one ever will, implying that unless a person can identify them as alone 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 by rights with others. During rate 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 injury 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 have discovered that he is 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 adenine admissible as their assets, impress them as nothing had since the day their maid declared their isotropy something to be feared and they agree to give the Host Club a prospect .


The Hitachiin family can not be described as a cohesive kin unit, as they do not spend much time together. Both Hikaru and Kaoru frequently mention that their parents work a set and, as a result, can not be there for them. This leads them to rely and depend only each other, hence their somewhat self-isolating tendencies .
The younger of the twins and the more centrist of the two, Kaoru willingly helps Hikaru understand himself and others well. Although the two worry for and respect Haruhi ( as she was the first gear one to truly enter their world ), they ‘lose ‘ her to Tamaki. Despite his patronize insinuation and teasing, Hikaru has been shown to be very protective of his younger gemini. Before the Hitachiin twins joined the Host Club, both Hikaru and Kaoru are socially awkward and inseparable, but gradually, they begin to open up to people. Although their brotherly bond is strong in both the manga and zanzibar copal series, both storylines end up with the twins seeking greater independence for themselves. Though Kaoru is the one to initiate their independence, it is Hikaru who validates their independence by dyeing his hair a dark shade of brown so people can easily tell them aside .

Hikaru ‘s beget, Yuzuha Hitachiin, is a celebrated fashion graphic designer of her own company. Hikaru ‘s grok fashion sense, appearance and personality come from his mother ( though he and Kaoru once jokingly mentioned that they fear for their future, due to their inherit shyness from their founder ). A running gag in the manga is the fact that Yuzuha constantly confuses them. Tired of correcting her, the twins allow her to call them by either name, even though it is former revealed that she actually can tell them apart, but pretends not to for her own entertainment .
Hikaru ‘s beget, whose name is obscure but who adopts his celebrated wife ‘s surname, runs a calculator software ship’s company. He appears to be a more down-to-earth person than his spouse and sons and is frequently hidden in the shadows, appearing invisible to everyone else around him ( including his class ) ; at one bespeak, Haruhi even mistakes him for Yuzuha ‘s bodyguard. The Hitachiin patriarch is besides noted to be one of the few people who can systematically tell the twins apart, even if their backs are turned to him. Although he does not show his emotions easily, it is apparent that he cares much more for his children than he lets on and gives good advice when necessity .
Kazuha is Hikaru ‘s grandma. She is known to be a free-spirit and well-known floral graphic designer who decorates her hair peculiarly with flowers, earning the twins ‘ ridicule. It is later revealed that the twins made up the hairdo as a prank when they were toddlers. As children, Hikaru and his twin would draw their own floral designs, but upon learning that their grandma wanted to use the designs on bath tissue, they decide that she is a hex who is incapable of being decent to others. however, eleven years late, she admits that she kept the draw and that the twins have great endowment. She is noted to travel frequently and rides a motorbike .
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 honestly 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 silent 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 ” box. Hikaru, like his brother Kaoru, frequently plays jokes on Tamaki and finds it specially amusing to tease the Host Club President over his desire to be called “ King ” ( aka Tono/Boss ) and, alternatively, calls him an idiot. Knowing that Tamaki loves Haruhi, even if he is unaware of it, both twins flirt with her infinitely to prod him into reality or good to get him fired up for their entertainment. An exemplar of this is seen in Ep 07 – jungle Pool SOS ! when they trick the blond into a water artillery fight by telling Haruhi they are going to marry her and go on honeymoon which effectively gets Tamaki into the fray. Despite being frequently exasperated by them and calling them “ fly-by-night twins, ” he authentically seeks their benefit .
Despite Hikaru and Kaoru ‘s efforts to remain a single entity, it is Haruhi who manages to decipher which twin is which without resorting to guesses, as she sees them as two different individuals. Because of her entrance into their closed-in world, and her acceptance of the two as both exchangeable so far different, Hikaru finally falls in sleep together with her and becomes highly genitive of her in the summons .
Although Kyoya frequently observes the twins ‘ activities, he does not peculiarly like to interfere with them. He has besides been shown to like their “ Forbidden Brotherly Love ” work, as it generates tax income for the clubhouse ‘s treasury. however, as Hikaru is more aroused and less rational than his buddy, Kaoru, the Vice-President does not become particularly close to the elder Hitachiin match ; alternatively, he prefers the younger Hitachiin twin ‘s more sensible nature .
Kazukiyo Soga is the Class Representative for Class 1A. He is the only early megane character in Ouran, though very different from Kyoya. He is 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 chilling cat. They band with him and Haruhi as Team B, pranking him relentlessly until they see what they think is the Clocktower Witch. In bulk 13 of the manga, Kazukiyo and Kaoru plowshare a room together during the class ski trip, and Hikaru ends up joining them on the second night when rooming with Haruhi becomes besides awkward. The follow day Hikaru forces Kazukiyo to ski down an expert slope and Kazukiyo twists his ankle, forcing Hikaru to piggyback him to condom. He is subsequently seen at the Hitachiins ‘ New Year ‘s Eve party, assuring a group of girls that his peg 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 backdrop cheering him on .
Mei is an aspirant designer and a huge fan of the twins ‘ fashion designer mother, Yuzuha. After accompanying Haruhi to the Hitachiin sign of the zodiac and suffer Yuzuha, Mei gushes that she is the “ perfect ” womanhood. not so far used to their personalities, she falls for respective of Yuzuha ‘s and the twins ‘ pranks. Being the first person to realize Haruhi ‘s feelings for Tamaki, she is besides the one to bring it to Hikaru ‘s attention, causing him to become intensely jealous of Tamaki, even though Hikaru is still forgetful to his own romanticist feelings for Haruhi. Before she can help Haruhi understand her jumble feelings for Tamaki, Kaoru calls Mei ‘s cell and urges her to stop so as not to give Tamaki an advantage over Hikaru. The twins get along well with her. They besides invite her to the New Year ‘s party at their mansion, where Kaoru expresses his concerns to her about Hikaru ‘s confession to Haruhi. Mei besides tells Haruhi that while it was uncivil of her to not notice Hikaru ‘s feelings, it would be tied worse to date him out of compassion. When Mei is studying fashion in college, the twins agree to be models for her fashion appearance, but send Kasanoda in their plaza in a system to set the two up on a date .
