Hyperdimension Neptunia Wiki
Don't be misled. Information is the nature of my profession. I've monitored your movements since your arrival.
— Kei Jinguji

Kei Jinguji is the Oracle of Lastation. Much like Noire, she is very hardworking and also a cutthroat businesswoman who will only do things if it will benefit her as well.



At first glance, Kei seems like a boy but in reality she is a girl. She has short silver hair and cobalt blue eyes and wears a black suit like outfit with a blue tie and black shorts instead of pants. Her legwear consists of below the knee black socks and black shoes with blue line designs and silver circles in the center.


Kei is a very dedicated and hardworking individual who always keeps her nation and her goddess' best interests in mind no matter the situation. While she seems initially seems manipulative, only caring about work and profit, she is shown to have caring aspects about her as well. An example of this would be when she asks Nepgear what happened in the Gamindustri Graveyard due to being concerned about Noire's well being.

The Crossroads of Defeat

When Nepgear, IF, and Compa arrive to the Basilicom they are greeted by Kei who says that she has been monitoring their movements since they had arrived in Lastation. When asked for information concerning Lastation's mascot character, Kei requires the girls to preform some manual labor and obtain the necessary components to a device being developed by Lastation.

Before Nepgear and company head out to retrieve the materials, Kei asks for information about what happened in the Gamindustri Graveyard three years ago and most recently. Nepgear is about to explain before being cut off by IF who says it is wrong for her try to pry information out of others for free. Kei apologizes and requests that they proceed in bringing back the materials, promising that they will exchange information once the task is completed.

After the party retrieves the Treasure Gem in Virtua Forest Depths and returns to Lastation in search of the Hematite, they are met with a young solider who offers to help them find it in exchange for defeating a monster. They quickly accept and take off to complete the task.

Kei, who had been watching the entire time, approaches the young soldier and tells him that he had done a decent job in making them go out and take care of the monster which implies that Kei was the one who put the solider up to the task in the first place. Kei also states that he had given Uni the same information about the Hematite that the soldier had promised to give to Nepgear.

The party returns to Lastation’s Basilicom and hand over the components that Kei had requested. Nepgear asks again for information on the mascot character. Kei first requests that Nepgear tells her what happened in the Gamindustri Graveyard.

After explaining, Kei is relieved to hear that Noire is alive. She then begins to tell them where they can find the mascot character of Lastation but also tells them that they shouldn't expect their request to be accepted. Kei wishes them the best of luck and sees the party off.

After having completed their mission, the group heads back to the Basilicom in Lastation to report their success to Kei but as always Kei already knows. Nepgear requests to meet with Uni one last time before they head to Lowee. Kei tells her that Uni panicked upon their arrival and dived melodramatically under her desk.

When Uni comes from under the desk, she and Nepgear exchange a few words in and end up rebuilding their friendship. Kei apologizes for giving Nepgear and the others the runaround and wishes them the best of luck on their journey. IF says that those words are creepy coming from Kei. Kei merely says that she surmises that Lowee’s CPU Candidates will be even more troublesome for them making Nepgear curious as they leave.

Final: Defenders

In the True Ending of the game, Kei watches Noire and Uni complete some paperwork. Kei is impressed that Uni has changed so quickly, from the fact that she had difficulty completing paperwork to the point where she was able to complete it quickly and flawlessly then Noire.

Apocalypse: Savior's Sorrow

With Lastation's shares falling quickly to Planeptune, Kei asks Noire and Uni what to do. Noire and Uni decide to confront the Planeptune sisters and fight them. When Nepgear arrives at Lastation's Basilicom, Kei summarizes that if she was here, Noire and Uni were already dead. Nepgear apologizes to Kei for having to kill both of them, and Kei kindly asks her to leave. When Nepgear leaves, Kei breaks down, commenting on how difficult it was to keep her usual business stance with Noire's death.

In the Conquest ending, Kei is the only Oracle to arrive to Nepgear's CPU ceremony (barring Histoire), stating that Mina was still upset over Blanc, Rom and Ram's death and that Chika refused to believe Vert was dead. Not having anything to do now that Lastation ceased to exist, she decides to work for Nepgear to normalize relations between her and the people.
