Uni is Noire's younger sister. Uni seems to be friendlier than Noire is, and befriends Nepgear quickly in the game until learning of her relation to Neptune. However, she is still very much a tsundere.

While she and her sister look nearly identical, Uni is a lot friendlier and perky in comparison. Comparing her relationship with Nepgear, it's a lot better then Neptune and Noire's at first. Much like her sister, however, she is a tsundere and says things like "I guess I'll let you...".

Uni seems to take pride in her fighting and is usually practicing in her spare time or learning how to take over Lastation possibly, as seen in one of the ending images where she is seen practicing karate with a nervous/worried Nepgear, or how she can be seen doing sit ups in another official picture.

Uni seems also to be less serious then Noire and seems to enjoy her time with the other younger sisters. She has her times however, such as helping the others in one manga chapter when they dressed as spies and snuck into a Pirachu-esque place

It's mentioned she does not like to be girly, meaning Uni may have tomboy traits which can be shown during her last Chriper event she has a hobby of collecting guns and in another event where she rather prefers to play at an arcade with Nepgear than do thing a normal teenage girl would do. She eventually gives in however, upon rescuing Noire and after Noire later comments on how strong she's gotten Uni begins to cry in joy much to her sister's surprise. Uni is also self-conscious of her appearance shown when Nepgear asks about her breasts when she transforms for Uni to angrily deny the topic and say it's now off-limits. She also is highly jealous and shocked when she finds out her underwear was sold for the least price in an auction by Gust who was selling the CPU Candidates items.

Uni is a light skinned girl with long black (almost light blue colored) hair with most of it worn down reaching her chest with some of it worn in pigtails held with light blue and black ribbons. Her eyes are red like Noire's but are darker in comparison. Uni's color scheme consists of black, milky blue, and white/silver. Wearing a black dress with milky blue lining, a odd belt like piece with a bow behind it and a big circle with white lining connecting the dress to her collar. She wears long fingerless black gloves with milky blue coloring at the top and similar short boots. On the left side she can be seen with a small device that is most likely a cellphone (or even a PSP in reference to her theme).

Her eyes become bright green. Her outfit, consist of a normal bathing suit like body piece greatly resembling her dress with more detailing on each part and two big circle pieces worn in her hair.
