Uni V2

Uni (ユニ, Yuni), also known as Black Sister (ブラックシスター, Burakku Shisutā), is the CPU Candidate of Lastation and Noire's younger sister. She represents PlayStation Handhelds which is referenced through her appearance in both forms, her processor units, and some of her dialogue.

Due to the Neptunia series being a game that revolves around different universes and dimensions, there are multiple Uni's throughout the series though all of them retain more or less the same personalities and core aspects regardless of the setting.

Trivia Edit

  • In the group picture, Uni has six fingers. While this was fixed in the artbook, it still exists in the game.
  • Uni's bust size is the only one of the goddesses that decreases upon transformation instead of staying the same or increasing like everyone else's.
    • In an event in Hyperdimension Neptunia mk2, this causes Nepgear to wonder whether it's not that Uni's breasts shrink, but that Uni had just been stuffing them in her human form.
    • In MegaTagmension Blanc + Neptune VS Zombies, Uni mentions how much she hates the series being mean to her on that issue after seeing Peashy transform.
  • In a popularity poll, Uni placed 5th place, making her and Noire the second most popular sister group right after Neptune and Nepgear which placed 2nd and 3rd, although Noire did come in 1st.
  • Uni's shrinkage after she goes HDD is a reference to how each models of the PSP is smaller and lighter than the last (PSP-1000>PSP-2000/3000>PSP Go).
  • In the stinger for the True Ending of Hyperdimension Neptunia Re;Birth1, Uni alludes to her representation by referring to the Vita handheld as herself while thanking the player. This dialogue was not removed in the PC port.
  • During one of the Nepstation segments in chapter 7, Uni and Neptune make a Pretty Cure reference, with Uni quoting the line "Blue Hard is the brand of hope! Freshly shipped just for you". This quote is derived from one of Cure Berry's catch phrases, who is a member of the Fresh! Pretty Cure team. Uni's Japanese voice actress, Eri Kitamura, plays Cure Berry.
  • Uni has developed a habit of gaining a close relationship with male robotic characters. CFW Brave in Hyperdimension Neptunia mk2, and Steamax in Megadimension Neptunia VII. This is ironic considering her best friend, Nepgear, obsesses over robots.
  • Despite Neptune being the one whose character is involved in breaking the fourth wall, Uni is the only one who has an attack that does exactly that.
