Haruhi Fujioka is the main character of the Ouran High School Host Club series. She is an intelligent first-year student from a middle-class ("poor" to Ouran standards) family who attends the Ouran Academy on a special scholarship that requires her to rank first in her class.
Haruhi is, above all, independent and straightforward, and believes that your gender should not define your personality. Since she was raised differently from her classmates at Ouran, she displays more practical, down to earth, responsible qualities and is not easily swayed by the charms of the other hosts. Even when she first meets the hosts, she only reacts nervously instead of becoming immediately infatuated like most of the girls. Haruhi has a deeper voice than other female students, so she is not easily recognized as a girl.
Although habitually unflappable, it is shown that she fears thunderstorms (Brontophobia), which terrify her to the point that she is stricken with paralysis. She enjoys peace and quiet, doesn't mind working, and is a fanatic about fancy tuna, which is used as a bribe to get her involved in some of the more peculiar Host Club schemes. Without bribery, Haruhi is described as "apathetic" by the twins when it comes to making some decisions, usually with regard to the host club. Haruhi is sometimes unaware of her own feelings, like her feelings of love for Tamaki shown in volume 13.
At her middle school, it was said that a boy would confess their love at least once a month. She becomes a popular Host in Ouran, with her regular conversations and charming smiles. She often shows her exasperation and distaste for the club, and even her fellow members, but she cares deeply for each of them. They, in turn, love her and regard her very highly, though they don't all put it into words (e.g. Kyoya and Takashi). All six of them are very protective of her.
In the manga, she and Tamaki Suoh (the princely host) become a couple as the series ends. They have an unnamed child whose name is Ren, but nothing else is known.
In her first appearance
Haruhi is introduced with a very geeky, boyish look: short messy hair, big glasses, and a baggy outfit. Haruhi has a slender build, causing her body to lack feminine features which is mentioned a few times throughout the series. She has brown hair which she cut shortly after a boy stuck gum in there a few days before school.
She sometimes has to wear a long wig that resembles how her hair used to be. Clients often comment on her big, shining eyes, saying they give her a more girlish look; the shining actually being caused by her contacts that were given to her so she wouldn't wear her glasses. Throughout the course of the series, many people - girls and boys - grow a crush on her after seeing her charming smile and her natural nature. She resembles her late mother who was a lawyer. She has worn a dress at Ouran a few times, usually as a disguise. Just before she left to study abroad, she revealed to the school she was in fact a girl. The students were very shocked when they learned of her real gender but accepted and embraced it soon after. Haruhi is 155 cm tall (5'1).
Reason For Cross-Dressing
She joined the Host Club to pay off a ¥8,000,000 debt after breaking an expensive vase which was to be used in an auction. At first, due to her short hair and androgynous clothes, everyone believes she is simply a feminine-looking boy (apart from Kyoya Ootori, who knew she was a girl from the beginning and the others found out along the way during the first episode.) Even after the club found out her true gender, Haruhi still wanted to work off her debt as a host.
