Personalities:
*- One word for their personalities is "dry." Very avid about things they are interested in but quite apathetic toward things they are not.
*- Unlike Tamaki, they are wholly calculating in their customer relations. They think women are easy. Still, they're just kids, so they sometimes do unexpected things. (i.e. In "Hunny's Bun-bun," they were "pretending to be scared," but in the end, they were genuinely upset.)
*- They're not really partial to spicy foods, so much as being contrary by eating whatever's "so fiery that nobody else dares try it." They do love maple syrup, though. Perhaps not the most ideal dining companions.
Hikaru Hitachiin is a first-year student at Ouran High School, and the older of the Hitachiin twins. He is usually the one that leads his brother into the different kinds of trouble-making they come up with. His words and actions a bit more evil than his brother's. He is loud and particulary crazy about schemes and mischief. He also doesn't care if he's being rude or obnoxious, especially if he thinks he's in the right.
Though he may act tough and uncaring, his one weakness is his brother. He cares for him deeply, and if he's hurt, he gets upset easily, though he won't show it to anyone but Kaoru. He is also particularly fond of Haruhi, since he and Kaoru have accepted her into their little world. However, he can't accept that Haruhi has had a life and friends before her time at Ouran. He gets extremely annoyed when Haruhi talks to an old friend, both jealous and not understanding why she needs other friends besides them. He gets angrier a lot easier than his brother. Kaoru usually tones him down just a bit.
Hikaru doesn't have many people that matter to him. He is codependent on Kaoru, and tends to shut out everyone else. He is especially immature and acts out his feelings without restraint. He only knows how to throw his feelings around rather than expressing them calmly, so he looks like a possessive kid. He doesn't know how to go about showing his genuine feelings. Hikaru still has to learn the basics of personal interaction.
However, with the awareness of his feelings for Haruhi (V11C50) and what his brother has done to help him (V12C53), Hikaru is finally stepping up in the big brother role. He has also changed his hair color to dark ash (V12C53) so that others may find it easier to tell him and Kaoru apart. He's come to the realization that while he and his brother used to resent others for their inability to tell them apart, he and Hikaru didn't exactly make it easy either. They need to give others a chance before completely writing them off.
Hikaru has now recognized his feelings for Haruhi and does his best to win her over. He eventually confesses. Haruhi later rejects him at the New Years' party, but she also denies loving Tamaki. Hikaru, not oblivious to the fact that Haruhi obviously cares for Tamaki, still sees he has a chance to win her over. He's not going to give up anytime soon and urges Tamaki to also face his feelings. Hikaru is beginning to show that he's growing up, and only time will tell if he can succeed in winning over the girl he loves.
