High school boys and dating
Though often exasperated with her fellow Host Club members, she cares deeply for them, in her own way.
Despite that, Haruhi and Ryoji still value Kotoko in their lives and Haruhi still looks up to Kotoko as her role model in life.
Ryoji Fujioka is Haruhi's cross-dressing father who works as a professional entertainer and asks that the hosts call him by his stage name, Ranka.
When first introduced in the anime, she sports a nerdy, boyish look that differs greatly from her middle-school appearance.
Having gotten gum in her hair just before school begins, she cuts it short and being unable to afford the expensive Ouran uniform, she wears shapeless, baggy clothing.
She is also rather oblivious when it comes to her own emotions; an example of this is her unawareness of her developing love for Tamaki over the course of the series.
Upon being designated a host, she becomes an immediate hit with the ladies due to her conversational skills and her charming smiles, gaining her the title of the "Natural" type.
Having been raised under less affluent circumstances than her classmates at Ouran, she displays more practical and responsible qualities, and is not easily swayed by the charms of the hosts.
Even when she first meets them, she only reacts nervously instead of becoming instantly infatuated like most other girls.
As she is required to remain first in her class to keep her scholarship, her studies are very important to her.
Two characteristics that define Haruhi are her straightforward nature and her belief that one's gender doesn't define one's choices.
Haruhi also has a deeper voice than other female students, has short hair and dresses androgynously most of the time, she is not easily recognized as female.
