While not above manipulating them for her own reasons, she appreciates the other host's protectiveness of her and their genuine desire to "make every girl happy." The series shows how Haruhi interacts with each of the hosts in different ways and how her relationships with them evolve over time.Haruhi tends to be apathetic towards events, preferring to remain at a distance and observing until she needs to act, she is astute in gauging other people's motives.
Her father has a temperament similar to Tamaki's and works as host/bartender in a cross-dressing club to support their middle-class lifestyle, which contributes to her lax attitude towards gender.
She is practical and honest to a fault but also caring and insightful.
Haruhi dislikes needless extravagance, often finding the antics of the Host Club annoying, and has a distaste for the artificial.
The Ouran High School Host Club characters have been praised as well-rounded comedic creations that "play on bishōnen stereotypes", a theme commonly found in other Japanese manga.
