hikaru and kaoru- both twins in the anime show, ouran high school host club. they are both twins and don't have lots of friends outside the host club (to there own choosing) they are identical twins and enjoy playing tricks on people in the host club. only haruhi can tell them apart and she is the only one who has ever been able to get close to them (in an emotional way). the twins are only apart sometimes, other than that they are never separated. they are seen as the 'little devil types' in the host club and are thought to be in an incestious relationship, they sleep together (strickly non-sexual, or is it?) and the members of the host club see it as 'brotherly love'. they have only had one fight which led them to changing there hair color to tell each other apart. they have a very strong bond and sometimes complete each others sentences.
Hikaru= Listen, just the fact that were both handsome types and homo scores a lot points, and while our act swings between friendship and homo is favorable enough...
kaoru= in our case we just use the biggest taboo of us being twins as our biggest weapon.
I LOVE HIKARU AND KAORU:)!!!!

Get the hikaru and kaoru mug.
These two are the twins of Ouran High School Host Club. They tend to tease Tamaki Suoh and enjoy pulling pranks on other members or friends.

Generally their entire display is a forbidden love between two brothers, also known as twincest or Hitachiincest.

They were originally only prone to spending time with each other due to people never being able to tell them apart (and their parents were always too busy to pay attention to them). However, when Haruhi Fujioka came around they soon had another person to add into their little circle of trust.

They often play the "Which one is Hikaru?" game in order to stump their fellow students (the only way to tell them apart, so they think, is which way they part their hair which they change daily). However, in the anime an easier way to tell them apart is their voices.

Their trust issues originated from a maid who had worked for their parents who betrayed them. They had liked her because she would play with them, but upon stealing money from their family they caught her in the middle of the act in which she said, "No one will ever be able to tell you two apart!"

Hikaru Hitachiin is more notorious for causing trouble than his younger brother Kaoru. He also has been known to have a small crush on Haruhi Fujioka (though he does not know it, while Kaoru does).
Hikaru and Kaoru Hitachiin are known as "The Little Devil Type" according to Renge.
