Uni is Noire's younger sister, though they look nearly identical. The main difference is personality—she's noticeably friendlier and more laid-back than her older sibling, with a perkier attitude overall. That said, she's still a full-blown tsundere who'll drop lines like "I guess I'll let you." without missing a beat.
She hits it off with Nepgear pretty quickly, at least until finding out about her connection to Neptune. Their dynamic is way better than what Neptune and Noire have at first, partly because Uni just seems to enjoy herself more. She likes hanging out with the other younger sisters and doesn't take things as seriously as her sister does—though she can buckle down when needed, like when she helped the crew pull off that spy mission in one of the manga chapters.
Uni's got a competitive streak and genuinely takes pride in combat. She's constantly training, practicing karate, doing sit-ups, you name it. There are hints she's preparing to eventually take over Lastation, though whether that's just something she daydreams about is unclear. She's not into girly stuff either—she collects guns as a hobby and would rather hit up an arcade with Nepgear than do typical teenage girl things. That said, she does have her self-conscious moments. She got genuinely upset when Nepgear asked about her body after transformation and shut that conversation down completely. She was also weirdly jealous and shocked to learn her underwear sold for the cheapest price in an auction—even less than what Gust was asking for the other CPU Candidates' items.
When Noire later compliments how strong she's become, Uni breaks down crying with joy, which catches her sister completely off guard. It's a rare moment of vulnerability that shows there's more going on beneath the tomboy exterior.
Her outfit is distinctly her own despite the family resemblance—she wears a black dress with milky blue trim and a quirky belt-and-bow setup, long fingerless black gloves with blue accents, and matching boots. She's got long black hair (with hints of light blue) worn mostly down to her chest plus some pigtails tied with light blue and black ribbons. Her red eyes are darker than Noire's. She carries what's probably a cell phone or PSP on her left side, keeping things modern. Her color scheme is black, milky blue, and white/silver throughout.

In HDD form, Uni becomes Black Sister and honestly looks almost identical to Noire's Black Heart—both rock the black, silver, and white palette. The main visual differences are Uni's bright green eyes instead of Noire's glowing blue-green, and Black Sister's outfit is actually a bit more revealing overall.
Her hair transforms into very light gray or white and gets styled in curled ringlets that spike outward at the bangs, with shorter, tightly curled side parts. The outfit itself resembles a bathing suit layered over her normal dress concept, with way more detail work throughout, plus two large circle pieces worn as hair ornaments.
