Uni/Black Sister

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. She is stubborn and always strives for perfection. Her seemingly flawless sister serves her most obvious complex.

Uni
Uni is similar to Noire in personality regarding some aspects such as the tsundere factor. Overall, however, Uni seems to be much friendlier and a lot less arrogant than Noire due to the inferiority complex she has from striving to be just as flawless as her older sister. Uni in Megadimension Neptunia VII has become a lot more observant in other people's dialogue. She notices when people say things that contradict each other, various traits from their dialogue, and other strange things.

Black Sister
Black Sister's personality is identical to her human form though, as with nearly all the goddesses, she becomes a lot more confident in her abilities and more serious.
