Kei Nijimura

"That Higashikata Family knows something."

- Kei Nijimura

Kei Nijimura (虹村 京) is a side character featured in the eighth part of the JoJo's Bizarre Adventure series, JoJolion. Appearing as an antagonist in the "Paisley Park and Born This Way" story arc, she then becomes a neutral character.

Kei is the Higashikata Family household's housekeeper. She is eventually revealed to be the daughter of Holy Joestar-Kira and thus Yoshikage Kira's younger sister. Kei is a Stand User who wields the autonomous, chilling Stand, Born This Way.

Appearance
Kei is a beautiful young woman with long, black hair which is normally tied in a bun with the exception of her meeting with Josuke with her hair down.

She wears a maid's uniform consisting of a black blouse and a white apron decorated with two pins that resemble lightning bolts and the letters G and U on each pin. And on her head, she wears a chin-strapped black hat also decorated with the letters G and U.

Her pantyhose are patterned with stars, and her shoes were designed with a bow-knot.

When confronted by Josuke, it is revealed that she bears a star-shaped birthmark near her left shoulder.

Since "Nijimura" is merely an alias, her true last name is likely either "Joestar" or "Kira".

Personality
Kei typically performs all the duties expected of a maid and shows no emotion whatsoever. It is eventually revealed her emotionless demeanor is a facade when Josuke asks her if she attacked him on the Higashikatas' orders. Kei reacts harshly to this, showing that she hates the Higashikatas, calling them "the goddamn Higashikatas". She also threatens to kill Josuke if he approaches Holy because she is revealed to be Holy's daughter, shedding tears and becoming more emotional.

After Josuke finally gives into her demands, she breaks down and reveals that they knew each other in the past, and she is surprised that he has really lost all of his memories. She also points out the seams in his halved eyeballs and tongue.

Kei's great love for her mother is shown again when she cares for the comatose Holy at TG University Hospital, cleaning her up and referring to her as "mama" as she does so.

Stand
Kei's Stand Born This Way is an automatic Stand that activates when the person she has targeted opens something. It manifests as a humanoid Stand riding a motorcycle that produces extremely cold winds, capable of freezing water vapor in the air.

Background
Kei is born from the union between Holy Joestar-Kira and Yoshiteru Kira, and she is Yoshikage Kira's little sister.

Although aware of her mother's illness, Kei took no part in helping Yoshikage steal and keep the Locacaca from the Locacaca Smuggling Organization. Instead, wary of the Higashikatas, she infiltrated the Higashikata Family, posing as an unrelated maid and taking the name "Nijimura" to investigate their secret.

After the earthquake of March 11, Kei discovers the supernatural properties of the soil near the Wall Eyes, which can exchange parts between two buried objects.

Meeting Josuke
Upon entering the Higashikata household, Josuke Higashikata is coerced into taking a family photo. Kei appears and attempts to remove his hat, causing Josuke to feel threatened, and ask who she is. Norisuke Higashikata IV answers for her and introduces her as the Higashikata family's housekeeper. When Norisuke shows Josuke around the house, he tells him to ask Nijimura for anything he needs. Later, as she helps Yasuho Hirose exit the premises, she relays a message from Norisuke, stating that Yasuho is not allowed near the Higashikatas' house again.

Seeing that Josuke has investigated her family tree and taking him for an enemy, Kei unleashes her Stand, Born This Way, on Josuke just as he decides to go see Holy. Nonetheless, Josuke escapes Born This Way and surprises Kei standing near the hospital. Kei tries to summon Born This Way one last time by tossing an opened pen to Josuke but Soft & Wet knocks her out before it can attack. Josuke manages to defeat her, but Kei stays aggressive and warns Josuke not to approach her mother. Josuke decides to be diplomatic and concedes, leading Kei to trust him. Examining his face, Kei notices that Josuke's eyes and tongue are in fact a blend of two organs.

Kei subsequently leads Josuke to the Wall Eyes and shows him that he is a fusion of her brother Yoshikage Kira and another person. She demonstrates using a lemon and a tangerine, burying them underneath the soil. She then unearths the fruits and then slices each of them in half, showing some of their sections swapped.

Every Day Is a Summer Vacation
After Jobin returns from his trip, he gives souvenirs he's bought from the trip to his family, including Kei and Josuke. He gives Kei an Oscar statue from a trip to Southeast Asia, which Hato grows jealous of.

Hato's Boyfriend
When Hato brings her boyfriend Tamaki Damo home, Kei is the first to be liquefied by Damo's Vitamin C as she tries to wipe off strange hand prints on the windows and furniture of the house. She spends the rest of the fight in a liquefied state.

Endless Calamity
During Tooru's pursuit in the Higashikata household, Yasuho immediately eats a Locacaca fruit after realizing that Tooru himself is the user of Wonder of U, who is then causing the calamity. She proceeds to use Joshu's phone to contact Kei Nijimura. At the TG University Hospital, Kei takes care of her mother in bed until she receives Yasuho's call. Yasuho tells her to hand the phone to Josuke as soon as possible. Kei notices that Holy has written notes about Josuke and his whereabouts and thus Kei is now able to go find Josuke in the secret Locacaca lab.

Disappearance
In the Higashikata household, a few minutes before the harvest of the new Locacaca fruit, Kei is seen missing in the family photo first taken during Jobin's visit to the family. It is unknown if she was purposely erased from the photo for reasons yet to be revealed.
