Haru Okumura | Spoiled Rotten

Her life controlled by her father, Haru would look away from the truth of both her own desires and her father's intentions, substituting for vague notions and superficial motivations. Aware of that, she would instead face her desire of freedom and betray him with the support of her newfound friends of the Phantom Thieves.

Haru is generally very shy and reserved. At school, she is viewed as eccentric due to her tendency to keep to herself and avoid contact with others as much as possible. She has serious trust issues, finding it difficult to differentiate between who truly values her as a friend, and who merely wants to use her for her family's status. This is due to her past, where not only friends, but adults and teachers would be kind to her just to please her father and smile at her for their own personal gain. Despite this, Haru is an incredibly kind-hearted girl. She becomes fast friends with all of the Phantom Thieves and is the only member of the group Ryuji Sakamoto doesn't argue with on a regular basis. She can also be very awkward, as shown when she first introduces herself to the others as "Beauty Thief," and forgets parts of the script she has rehearsed with Morgana, to the point of saying "We will take the Treasure!" twice in a row, much to Futaba Sakura's annoyance. She later explains that she was trying to be a "heroine of justice," having grown up admiring female superheroes she watched on TV. She loved them for always fighting to protect others and being happy, desiring to be just like them someday.

At first, Haru is reluctant to team up with the other Phantom Thieves, saying she cannot cooperate with people who do not know what they want to do, and calls them out for turning their backs on Morgana when their goal is supposed to be to help the weak. After the Thieves rescue her and Morgana from her abusive fiancé, Sugimura, she reveals her true intentions; she doesn't want to get married and deciding to be honest with herself, joins the Thieves to change her father's heart. Despite this, she is initially still reluctant to oppose her father, and as a result hasn't fully awakened to her Persona, though this changes once she learns that her father has no illusions of the kind of man her fiancé is and declares that she is no longer his "subservient puppet." Afterwards, she decides on the codename "Noir" (the French word for "black"), to remind herself that she is operating on the darker side of the law despite her desire to be a heroine of justice. As such, she is rather surprised to discover that the others decided on their codenames based merely on how their outfits look, when she had created such an elaborate backstory for hers. Regardless, Haru is mature, level-headed, and kind in almost every way. She is also described to be very feminine, as pointed out by Ann. She enjoys helping the Phantom Thieves, as she becomes delighted when she learns that her hobby of vegetable-growing can prove useful to the group's activities and is excited when Makoto proposes a Showtime with her. This is because she wishes to be seen as dependable by them but often worries that she may not be doing good enough and can be fairly self-deprecating when she expresses that doubt (shown when she claims that gardening is the only thing, she's honestly good at and calling herself "weird" during her counseling session with Takuto Maruki). Haru is shown to be easygoing, being very polite to teachers and authorities, and often showing a friendly smile to her peers when talking. She also has a rather refined speaking pattern, which contrasts someone like Ryuji, who speaks in a very casual manner. Haru can sometimes be playful and teasing as well but knows not to push limits and is never taken to a serious degree.

As someone raised under the teaching of "do as you're told," Haru is reserved and often lets other people decide for her, even describing herself as someone who's not adept at saying what's on her mind, yet she's aware that this isn't how she wants to live her life. Haru has grown to appreciate just about any freedom she can get, claiming that having the freedom to go out shopping, as opposed to just doing it online, is "a luxury in itself." Additionally, despite the fact that she has been forced to do whatever people wish of her, Haru is very empathetic and can easily see how easy her life is in comparison to the average person, and she really is luckier than everyone else to be born as rich as she is.
