Out of all the CPUs, Noire is the closest to Neptune. They are quite the opposites in personality, Neptune is lazy while Noire is a workaholic, Neptune can be read as an open book, Noire is nowhere so honest. Despite the difference in work ethic, Noire is willing to admit, no matter what, Neptune is her equal. She finds herself, usually at the end of Neptune's jokes one way or another even if she attempts to make fun of Neptune. In Hyperdimension Neptunia Victory and its remake, however, due to Noire winning the real life popularity contest, Neptune does not have such a high opinion of her and is partially driven by a desire to return to the Hyper Dimension to get revenge over the loss of her popularity but regardless, the two are always close. In Megadimension Neptunia VII, the two are once again closer as Noire is willing to fly at mach speeds to Planeptune just to assist Neptune. Neptune also has a knack for learning secrets about Noire and will tease her about it. Due to both goddesses being part of the main cast, they have gone through a lot and became very good friends.

CPU Candidates


Noire trusts her little sister Uni to back her up and is proud of her. However, she will admit in Hyperdimension Neptunia mk2, that Nepgear is stronger than her.

When Noire returns, she complains about the work that Kei did not help her complete, but somehow completes all the work anyways. Uni says that is how they usually work and it works out really well.
