Kei Nijimura

Kyo Nijimura (虹村 京) is a side character featured in JoJolion.

Kyo is the Higashikata Family household's housekeeper. However, she reveals to Josuke that she secretly is Holy Joestar-Kira and thus Yoshikage Kira's little sister. Kyo is a Stand User who wields Born This Way.

Appearance
Kyo 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.

Personality
Kyo 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. Kyo reacts harshly to this, calling her masters "the goddamn Higashikatas". She also threatens to kill Josuke if he approaches Holy, apparently out of more personal reasons, 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.

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

Synopsis
Upon entering the Higashikata household, Josuke is coerced into taking a family photo. Kyo 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 her employer that Yasuho is not allowed near the Higashikatas' house again.

It is revealed that Kyo is not only the user of the black biker Stand, but that she is the daughter of Holy Kira. After a struggle, she reveals that she was not an enemy of Josuke's, but an ally, and reveals the seams on his eyes and his tongue, revealing that he not only has 4 testicles, but also 4 eyeballs and 2 tongues.

She then explains to Josuke that he is not an actual person, but rather a fusion of her brother Yoshikage Kira and another person thanks to the Wall Eyes, which can swap the genetic material of any two objects buried near them. She tells Josuke the key to solving this mystery is through the Higashikata family and their secrets, which is the main reason she went undercover as their maid.
