Hikaru and Kaoru are the Hitachin twins. They are the little devil type. Hikaru seems to have a but of a crush on Haruhi. To make the girls go gaga over them they pull off "Brotherly Love" an act that seems like they love eachother in a weird way not like brothers. They are actually rather obnocious and love to get on Tamaki's nerves. When Haruhi comes along she is the only one who can tell the difference between the two and that's what make Hikaru like her. A serperation between him and his bro. not just him and Kaoru but another too. They both long for someone to like them as individuals although they don't look it in front of the girls.
