Kaoru Hitachiin is the younger of the Hitachiin twins and is in Class 1-A with his older twin, Hikaru; and fellow Host Club member, Haruhi Fujioka. Despite being younger than his brother, Hikaru, he is shown to be much more mature and level-headed.
Kaoru Hitachiin is the younger of the Hitachiin identical twins. He and his older twin, Hikaru, are introduced when Haruhi Fujioka stumbles upon the Host Club. Being in the same class as Haruhi, they serve as major rivals against Tamaki for Haruhi's romantic attention. Kaoru is just as playful as his elder brother, but is also 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 (but not malevolent) troublemakers. They are famous for their "Forbidden Brotherly Love" package, carrying out twincestuous 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. 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.
Both of the twins prefer to Tamaki as "Boss" in the English version and as "Sir" in the Japanese version.
AppearanceWhen not in uniform, Kaoru likes to wear somewhat outlandish designer clothing, but fortunately, almost always wears clothes of different style or different than color than his twin, Hikaru. In the manga, he has short, somewhat messy auburn hair. Kaoru has also dyed his hair powder blue, and later pink, to confuse the Host Club and their guests, though Haruhi still manages to tell the Hitachiin twins apart.</p>
When facing them, Kaoru's parts his hair to the left side, while Hikaru's parts his to the right; when they stand together Kaoru is usually on the left with Hikaru on the right. 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. There are differing opinions as to their height being either 175 centimeters (5'9") or 178 centimeters (5'11"); the former reflecting the anime, the latter reflecting the manga.
Kaoru's rose color in the Host Club is orange. In Japanese culture, this signifies happiness, matching him quite well as his nature is more optimistic when compared to Hikaru's. In Western culture, an orange (or coral) rose is symbolic of romantic energy and enthusiasm; Kaoru displays this in his eagerness to devote himself to his brother, his friends and the Host Club's clients.
As children, Hikaru and Kaoru are inseparable and dislike everyone with the exception of their personal maid, who 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 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 people can identify them as unique individuals, they're 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 they 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 continues until he gets it correct. His reasoning is intuition which they refute, but his persistence and 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.
Due to his constant monitoring of Hikaru's emotions, Kaoru has become adept at figuring people out. An example of this occurs during Ep 15 - The Refreshing Battle in Kuriazawa!, when Hikaru becomes jealous of Haruhi's childhood friend, Arai, and lashes out at the unoffending male before fleeing. It is Kaoru who helps his brother understand his error and who apologizes to Arai (dressed as Hikaru) before explaining to the Hosts, in depth, what makes his brother so difficult. He is also the one who sets up Hikaru's date with Haruhi (despite his own budding feelings for her), as he understands his brother's underlying romantic feelings for Haruhi and believes that she can help him learn how to be more considerate of others.
The Hitachiin Family
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.
Hikaru is undoubtedly Kaoru's closest life-long friend and companion. Despite being the older twin, he is immature, boisterous and somewhat selfish, to the point that he is extremely dependent on his brother to help him manage his feelings; thus, his social skills and emotional control remain undeveloped. In both the anime and the manga, they begin as two halves of a unified whole, symbolized by a plant with two entwined leaves hatching from one egg, but as the series continues, they develop their unique personalities and become individuals in their own right, symbolized by flowers of differing colors sprouting from their respective plants.
Mr. Hitachiin (The Hitachiin Patriarch)Kaoru and 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.
Kazuha HitachiinKazuha Hitachiin is Kaoru and Hikaru's grandmother. She is known to be a free-spirit and well-known floral designer who decorates her hair peculiarly with flowers, earning the twins' ridicule. It is later revealed that the twins made up the hairstyle as a prank when they were toddlers. As children, Kaoru and his twin would draw their own floral designs, but upon learning that their grandmother wanted to use the designs on bath tissue, they decide that she's a witch who is incapable of being nice to others. However, eleven years later, she admits that she kept the drawing and that the twins have great talent. She is noted to travel frequently and rides a motorcycle.
The little-seen younger sister of the twins, 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.
Before the Hitachiin twins joined the Host Club, both Kaoru and his elder brother were socially awkward and inseparable, but gradually, they begin to open up to people. Although their co-dependence is depicted as a strong force in both the manga and anime series, both storylines end up with the twins seeking greater independence for themselves. Kaoru is the one to initiate their independence, but it is Hikaru who validates their efforts by dyeing his hair a darker shade of brown (in the manga) to make it easier for people to tell them apart.Chapter 52 of the manga, in which he confesses his affection for her and kisses her cheek; however, since he values his brother's familial relationship more than a potential romantic relationship with Haruhi, he tells her that he will be giving up so Hikaru might have a greater chance of winning her heart. Ep 07 - Jungle Pool SOS!, where they antagonize him into a water fight by stating their intention to marry Haruhi and go off on a honeymoon. It should be noted that, despite being frequently exasperated by their antics and calling them the "shady twins," Tamaki genuinely seeks their welfare. 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, pranking him relentlessly until they see what they think is the Clocktower Witch. Kaoru and Kazukiyo end up locked in a room together where Kaoru is surprisingly friendly to Kazukiyo in the absence of his brother and Kaoru reveals that they had plans to make Kazukiyo appear brave and manly in front of his crush, Momoka. 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. 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. Ritsu Kasanoda in their place in a scheme to set the two up on a date.
