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.
The positive traits of this sign are honesty, curiosity, innovation and amiability; the negative traits being inconsistency, disinclination, detachment, deviation tendencies and inefficiency.
With her messily-styled hairdo, large glasses (which once belonged to her grandfather) and masculine clothing, she's thought to be male and Haruhi does nothing to discredit this idea.
Apart from the few times that she dons a wig during cosplay, Haruhi resembles a cute, somewhat short boy with cropped brown hair and two large brown eyes.
Apart from this, she tends to have a peaceful nature, refuses to shirk work and is crazy about gourmet food, especially ootoro aka fancy tuna (which is sometimes used as a bribe to involve her in the crazier schemes of the Host Club).
Without such bribery, however, Haruhi is described as "apathetic," especially when it comes to making decisions and, particularly, in regards to the Host Club itself.
