In the original, Kenichi Suzumura is Hikaru, Yoshinori Fujita is Kaoru. In the dub, Todd Aberkorn is Hikaru and Greg Ayres is Kaoru.
Hikaru and Kaoru Hitachiin are awesome because they are Hikaru and Kaoru Hitachiin. I mean, come on, there probably isn't one person on Earth who doesn't want to be them (or at least one of them).
Hikaru's hair is usually parted to the right (from OUR perspective, but his perspective it's parted to the left) and Kaoru's is usually parted to the left (again, from our perspective. From Kaoru's perspective, it's parted to the right). Also, in the anime, Hikaru's voice is lower, and firmer in the English sub. Kaoru's voice is higher pitched and softer. Also, according to Haruhi, when Kaoru isn't with Hikaru, "he is normal and well behaved, while Hikaru is noisy and has a bad mouth".
Well Hikaru has more of a clear voice and a little more high pitch then Kaoru's. Kaoru has more of a nazley voice and just a little deeper then Hikaru (at times but sometimes Hikaru is depper) . And plus Kaoru is sometimes more of a nicer person then Hikaru (when they are out of middle school) and that's how i tell the difference hope this helped :)
In chapter 53 of the manga Kaoru kisses Hikaru on the cheek.
Yes. His twin's name is Kaoru.
No, not that I know of. The only one out of the Hitachi brothers is Kaoru, he kisses Haruhi on the cheek while Hikaru was there and Hikaru got jealous but Hikaru does love Haruhi and Kaoru loves her too but loves Hikaru more and doesn't want to lose their brotherly relationship and gives up on Haruhi so Hikaru can love someone not only himself or Kaoru only. Hope this Helped This is in the manga by the way. AKA: THE BEST MANGA BOOK SERIES EVA!! ♥♥
Kaoru and Hikaru both have romantic feelings for Haruhi but Kaoru steps back to let Hikaru come to realize his feelings for Haruhi and encourages Hikaru to pursue his feelings. At least that is what I got from the anime but those reading the manga will have a much better understanding, I would think.
Kaoru is 37 years old (birthdate: February 17, 1974).
I think that was in "The Twins Fight" , which was episode five.
In the Haruhi in Wonderland episode, Hikaru and Kaoru were playing the role of the cats.
No, the Hitachiin twins are not gay. Hikaru and Kaoru are just acting that way to get the girls into the club.
