Haruka is a stubborn, protective individual, but is also strong-willed, capable, charming, and occasionally even doting. She is formally introduced in the third story arc, although she appears in silhouette alongside Sailor Neptune in the final episode of Sailor Moon R.
Haruka is a racecar driver, even though she is barely sixteen years old when she appears. However, the timing of her birthday to the Japanese school year means she is one grade ahead of the Guardian Senshi.
Among fans in North America, Haruka and Michiru are among the most famous out lesbian characters in anime. Haruka is also extremely flirtatious and loves to tease pretty girls who sometimes mistake her gender due to Haruka's tomboyish behavior. In the manga, she even kisses Usagi. Through out the manga, she is lightly flirting with Usagi, either out of habit from the first arc she appeared in or just for fun, and eventually Usagi would occasionally flirt back out of pure playfulness.
Although her relationship with Michiru is not implicitly sexual until later in the series, their romantic situation is referred to early on and generally understood by most of the metaseries' characters fairly quickly. It is sometimes a source of good natured humor, particularly because few of the other Senshi have serious romantic prospects in comparison and because the otherwise flirtatious Haruka finds it impolite to discuss romantic matters in public. All fan rumors about Haruka being a man, the reincarnation of one, or a hermaphrodite, are untrue. Naoko Takeuchi has explicitly stated that "Haruka has always been a girl. Always will be."
She further complicates the perception of her gender by appearing as a "Tuxedo Mask" instead of a Sailor Senshi in the first appearance. This form is never mentioned again.
Besides her relationship with Michiru, Haruka is also close friends with Setsuna, because the three of them work closely together as Outer Senshi. Following the destruction of the Death Busters and the rebirth of Sailor Saturn as an infant, they vow to be her family and care for her. Later story arcs show that the four live together happily for some time. Nothing about Haruka's family life is ever discussed, although she and Michiru Kaioh appear noticeably wealthy by unknown means. In the manga, Haruka says that she and Michiru have "wealthy patrons." Haruka is the target of sexism in episode 98 of the anime, but never of homophobia.
The anime and manga versions of the character are reasonably interchangeable, although her standoffishness is more pronounced in the anime. Like the other Outer Senshi, Haruka is sometimes considered colder and almost unfeeling. Aside from a brief vignette in a special, Haruka and the others do not return after the third season until the final fifth season, generally retaining the same personalities.
In the Sailor Moon musicals (Seramyu), Haruka and Michiru's relationship remains largely unchanged; they are always shown together, which is consistent with both manga and anime, and while their romance in the musicals is usually kept low-key, the actresses for the two do kiss on stage in the omake of Kaguya Shima Densetsu Kaiteiban. They are also the only two Senshi to engage in physical combat with Galaxia. The other Senshi only use their powers to combat her. As in the anime, however, neither Uranus or Neptune are capable of harming Galaxia in combat. It is seen that Uranus could sense Neptune's death when Galaxia gravely injures Neptune, who had been weakened while protecting Sailor Mars. Otherwise, the two are shown to be more willing to work as a team with the Guardian Senshi in the musicals than in the anime, except where plot-lines are directly drawn from the anime, such as their pretended betrayal of the other Senshi in Stars.
Haruka's greatest dream, prior to becoming a Sailor Senshi, was to be a professional racer. Thereafter it is still a well-loved hobby, and driving is listed in the manga as her best skill. She is also a skilled runner, belonging to the track-and-field club at school. On occasion, Haruka can be seen playing piano in accompaniment during Michiru's violin performances. While Physical Education is her best class, Modern Japanese is her worst. Haruka is highly private, able to tease others while becoming flustered if teased herself, and has difficulty with confessions. Her favorite food is salad, and her least favorite is natto (fermented soybeans); she also likes the color gold. According to Michiru, Haruka has had trouble with popular men on more than one occasion. Haruka denies this, but it clearly annoys her.
Haruka and the other Outer Senshi appear in the SuperS movie, although this conflicts with the general timeline of the series in several ways. Notably, they are more overtly friendly and helpful than they had been when they last met and Sailor Pluto is present (in contradiction of certain events in the third series).
Special powers and items Although Haruka is extremely strong and has some psychic sensitivity (mostly in the form of dreams, shared by Michiru and Setsuna, or by "hearing" ill omens in the wind), she is not shown using any special powers in her civilian form. She must first transform into a Sailor Senshi by raising her hand or a special device into the air and shouting a special phrase, originally "Uranus Planet Power, Make-up!" In the manga she eventually gains her Uranus Crystal and this phrase changes to evoke Uranus Crystal Power. In the anime, although she does upgrade to Super Sailor Uranus, the Crystal is never mentioned and her transformation is not shown on screen. When it is used, her transformation sequence involves a golden energy circle which encloses around her, forming her outfit. She is also once shown de-transforming—her outfit becomes flower petals as she walks away, leaving her nude for a moment before her normal clothes reappear.
Sailor Uranus' powers are inspired by Roman mythology, where Uranus is the god of the sky. She is often mistaken as having earth-based powers, but this is because of the appearance of her first attack, World Shaking, in the anime; she gathers energy from the sky and hurls this at the ground, breaking it up, but does not manipulate the earth itself with her will. She is given three major attacks in the series, and although they all have English names (like those of the other Sailor Senshi), each is also given kanji in the manga to denote the meaning to Japanese readers. For example, World Shaking is given kanji which translate to "sky" , "world" , and "shake" . The intended English pronunciation is given in furigana. This is Sailor Uranus's primary attack for most of the anime series.
Haruka carries a special blade, the Space Sword, which turns out to be one of three powerful Talismans, the other two of which are carried by Sailor Neptune and Sailor Pluto. In the manga, she seems to already know it is a Talisman; in the anime, she does not gain the sword until it is revealed as such. In either case, it is used in her second attack, Space Sword Blaster , as well as in physical strikes.
Her third and final attack, appearing only in the manga, is called Space Turbulence , which uses no item at all. The Uranus Crystal is perhaps her most important possession, as it is her Sailor Crystal and the source of all her power, which becomes especially important in the fifth story arc. It is given to her by Sailor Saturn.
