Editing Haru Okumura

Haru is the daughter of Kunikazu Okumura, a wealthy yet selfish and corrupt businessman and the fifth target of the Phantom Thieves. She is the heiress to her father's company, Okumura Foods, which is suspected to be in violation of several health and safety policies and may be connected to the mental shutdowns that the Phantom Thieves are looking into the cause of. Haru wishes to have her father's heart changed so she can escape her arranged marriage with Sugimura, an abusive and sleazy man that is only marrying Haru to strengthen the power and influence of both families. She meets [[Morgana]] while the latter has split off from the Phantom Thieves due to a disagreement; feeling inadequate thanks to a combination of [[Ryuji Sakamoto]]'s teasing and [[Futaba Sakura]] taking over his function as the team's navigator, he wants to help people on his own to prove his self-worth. The pair decides to enter Kunikazu's Palace and steal his treasure on their own. However, Morgana is easily overpowered, and Haru awakens to her Persona but is unable to summon it, forcing them to escape. When confronted by the Phantom Thieves (with Haru presenting herself as "Beauty Thief"), Morgana brushes them off. However, Haru's lack of confidence becomes apparent as she forgets dialogue the two of them had rehearsed earlier.

Later on, the Phantom Thieves rescue Haru from being assaulted by her fiance, prompting her to join the group with Morgana in tow, as he, [[Joker]] and the rest of the group make amends with each other. Upon reentering the Palace, Haru learns that her father cares little about his company, as he intends to branch off into politics in order to amass more power, and only intends on marrying her off as a means to an end, regardless of the fact that her fiance intends on abusing her. Her anger from this realization allows her to fully awaken her Persona, Milady, and under the codename Noir, she helps the group steal Kunikazu's treasure. Kunikazu holds a live press conference atoning for his behavior, but suddenly collapses as his mind shuts down just as he is about to reveal the identities of his co-conspirators; the Phantom Thieves, now at the peak of their popularity, are blamed for his death. Haru's social link, following this, revolves around her struggles in having to run her father's company, coupled with the general distrust she has of her employees.

Should the player pursue a confidant with Haru, she and the player are seen picking vegetables out of her garden. Haru explains how she wants to become more involved in Okumura foods, specifically wanting to make a café similar to one her grandfather ran. Sugimura also returns and threatens her with the arranged marriage, which he claims is still legally binding despite her father now being dead. Haru eventually brings her vegetables and coffee beans to the stand-in president Takakura. He is impressed by the quality, mentioning how they taste just like the ones her grandfather made, which convinced him to join the company in the first place. After mustering the courage to explain her plans for the business once she takes control, Takakura agrees to help her with the early phases of the transition while he is in power. Haru also brings up the arranged marriage, which Takakura explains that a formal legal deal was never signed and she can back out without consequence if she desires. After realizing this, Haru officially requests an anullment, cutting ties with Sugimura. Takakura invites her to the next corporate meeting so she can give a pitch about her plans for the future of the company. He also makes a passing comment that she must be close to the protagonist, who was beside Haru for the entire scene. Haru goes to the meeting and explains that she plans to attend college to get degrees in business management and food science to attain the skills necessary. Completing the confidant causes her Persona to change from Milady to Astarte.

When Takuto Maruki alters reality in ''Persona 5 Royal'', Okumura remained a kind man who loves his daughter, cares for the well-being of his employees and never died. The protagonist confronts the two making plans for a fast food restaurant with a natural motif that uses homemade ingredients. Haru eventually realizes that all of this is an illusion and resolves to let go of her desires. The illusion breaks and Okumura disappears. If her confidant had been completed before this, her ultimate Persona, Lucy, will be obtained from the fusion of Milady and Astarte. By the time of ''Persona 5 Strikers'', Haru is now a college student and returned for the summer.

In battle, she wields a single-shot grenade launcher and an axe, and she specializes in psychokinetic and gun skills.

Haru appears on the [[Mementos]] stage in her Noir costume. She, like the other Phantom Thieves, can also be heard randomly on the Results screen when Joker wins a battle.

Haru uses a {{SSBU|Villager}} puppet fighter and is fought on the [[Tomodachi Life]] stage's [[Ω form]]. She is fought along a [[Giant]] {{SSBU|Daisy}} puppet fighter, representing Haru's Persona, Milady. During the battle, the Food item (Salads) appear in large numbers, referencing Haru's hobby of growing and harvesting vegetables on the rooftop of Shujin Academy. Also, the Giant Daisy puppet fighter starts off with a [[Super Scope]], referencing Milady's usage of gun-based attacks.
