This article is about a/an monstrous Rider in Kamen Rider Zi-O.

"I will pronounce your verdict: Guilty!"
―Yuko's word to punish the ones who accused her before transforming into Another Kiva[src]

"Sougo...I don't need any an umbrella for humanity."
―Yuko's last word to Sougo before getting killed by Ora[src]

Yuko Kitajima (北島 祐子 Kitajima Yūko) is Another Kiva (アナザーキバ Anazā Kiba), an Another Rider derived from Kamen Rider Kiva.


Yuko Kitajima was originally the person Sougo thought was his first love, though it was later proven false.

Yuko smiles when she killed Tetsuya's new girlfriend.

In 2015 at the age of 24, she was arrested and incarcerated for a murder she insists she didn't commit. However, this was all a lie and she's indeed the one who commited said murder.

At the age of 28, Ora broke her out by turning her into Another Kiva.

Following the arrival of Kamen Rider Ginga, when the Time Jackers and the three main Riders convince her to fight alongside against this bigger threat, Kitajima outright declines, as she is more focused on her petty revenge. Thus, forcing the two opposing sides to deal with Ginga.

After Woz acquires the Ginga Miridewatch and transforms into WozGingaFinaly, he singlehandedly defeated Another Kiva using Chou Ginga Explosion. Now stripped of her powers, in an act of spite, Ora gave Kitajima an ironic death as punishment for defying her, and consequently dying in Sougo's arms.

Yuko's fate following the timeline reset by Kamen Rider Ohma Zi-O is currently unknown.


Yuko's personality can be likened to the Japanese term yandere, which refers to the initial stage of kindness, love, and gentleness, as she showed to her boyfriend at the time, Tetsuya. However when they broke up, Yuko became deranged and killed Tetsuya's new girlfriend, which resulted in her being convicted at the age of 24. Falsely believing the justice system has failed her, she strongly deluded herself that she was wrongfully convicted, and continued to be as hard-hearted and vengeful when she got out. She went as far to murder the lawyers and judge that gave her the guilty verdict as well as crashing her ex-boyfriend's wedding. Yuko seeks to be the Queen and new law of the world. She is fearless and arrogant, even dares to attack Ora, the Time Jacker who crowned her.

Despite not being the identity of Sougo's first love, she led him on to believe that she indeed was, and proposed marriage and having children to him. In the end before her death, she told Sougo to protect everyone from being sad, as she herself failed to.


  • Hyperosmia: Yuko can instantly smell and precisely point out what kind of perfume her target is using, and what foods or drinks they have recently eaten or drank.
  • Psychometry: In conjunction with her olfaction, she can observe small details on her target and easily deduce recent events in their life.
  • Superhuman Strength: Yuko can lift and use a manhole covers as a weapon even before becoming an Another Rider to kill people. After becoming Another Kiva, Yuko can use the manhole covers for either offensive or defensive purposes, and even throwing it like a frisbee in human form.

  • Manhole Covers: Possibly Yuko's favored weapon while in civilian form or simply for the purpose of using the surrounding environment. The cover could be used for either offensive or defensive purposes. It is also durable enough to guard even against Kamen Rider Ginga's energy attacks.

Behind the Scenes


Yuko Kitajima is portrayed by Yumiko Shaku (釈 由美子 Shaku Yumiko), who previously portrayed Eri Hinata in Kamen Rider G. As Another Kiva, she is portrayed by an unknown suit actor.


Her frequent usage of manhole cover has been made into meme which involves parodying said scene into various situations. In the Japanese fandom, this is labelled under the Twitter hashtag Manhole Crappy Collage Grand Prix (マンホールクソコラグランプリ Manhoru Kuso Kora Guranpuri).


  • Another Kiva bears a similar design to the Fangires.
  • She is the first Another Rider to be an Anti-Villain.
  • The desire created within her by Kiva Anotherwatch to become the "World's Queen" is parallel to that of Sougo Tokiwa, who wants to become a king.
    • Amusingly, Yuko indirectly proposes to Sougo to rule the world together after learning his dream.
  • Another Kiva is the second female host to become an Another Rider, the first being Amane Kurihara.
    • She is the first to use its original counterpart's weapons.
    • She is the first to be introduced in the Reiwa era.
    • She is the first to ever disobey the Time Jackers' orders.
  • As with most Another Riders, Yuko as Another Kiva is the opposite of Wataru Kurenai. Although Wataru became the new Fangire King in the end, he simply did so to create peace between humanity and the Fangires, along with protecting his half-brother. Whereas Yuko is a tyrannical control freak who abused her power to control people for her own gain, her pride in her power is similar to both King and Taiga himself, both are former Fangire Kings.
    • Yuko is also a stark contrast to Otoya Kurenai, the second Dark Kiva and Wataru's father. Otoya was an eccentric and charismatic ladies' man who is greatly respected by his peers, including his rival Jiro. Yuko is an individual with delusions of grandeur who believes herself to be a rightful ruler and is an outright liar who feigns being wrongly convicted. Her relationship with her ex-boyfriend is reminiscent of Otoya towards Yuri. Though Otoya broke up with Yuri on good terms after he later fell in love with Maya. Yuko killed Tetsuya's new girlfriend after they broke up, and even go so far as to attempt to kill his fiancée during their wedding.
    • Additionally, Yuko is the opposite of the aforementioned Maya & Mio Suzuki as well. The three women were granted the power of Queen to judge and execute others. Despite this, both Maya and Mio don't possess ill-hatred towards humanity and redeem themselves in the end. Despite Yuko not being the true identity of Sougo's first love, her death parallels Mio's death.
    • Yuko and Taiga share similar catchphrases.
  • Yuko is the second Another Rider to actually die, after Tid/Another Kuuga. However, while Tid was killed by all main Heisei Riders, Yuko was killed by one of the main Time Jackers.
  • During her time as Another Kiva, there was no sight of Kamen Rider Kiva anywhere, despite it being possible for both to co-exist.
