Blanc/Hyper Dimension/Relationships
CPUs
Neptune
Blanc sees Neptune as friends and fellow goddesses. Blanc is comfortable enough to come over to Planeptune and play games with Neptune. Neptune however, when she visits Lowee is usually given her sisters to play with rather than Blanc. Blanc describes Neptune as someone who pulls people around her, breaking away barriers that separate one another, including Blanc. Blanc does join in the other goddesses to call out Neptune on her laziness. Neptune is aware of Blanc's violent description and describes it quite positively to Plutia showing that Neptune respects Blanc. Due to both goddesses being part of the main cast, they have gone through a lot and became very good friends.
Noire
Hyper Dimension
Blanc and Noire are not really seen interacting just by themselves. They are usually with the other goddesses.

Ultra Dimension
Blanc holds off hordes of fake goddesses for Noire and the others to pass through to fight Rei Ryghts. Noire is impressed with Blanc's display of heroism and wishes she somehow let her counterpart pass so she would have a chance to look cool.
Vert
Hyper Dimension
With the introduction of Hyperdimension Neptunia Re;Birth2, Blanc and Vert start out hating each other, in the gameplay when looking at Lily Rank. However, the cutscenes do not show this. Vert and Blanc get along with each other as well as any other fellow goddess. Vert is a maternal figure to even Blanc. Vert happily gave Blanc pictures of Rom and Ram's cosplay. Vert even gave her ideas for her fanfiction. In the true end, Blanc had the idea of loaning out one of her sisters to Vert who, at the same time, had the idea of borrowing one of Blanc's sister. In Hyperdimension Neptunia Re;Birth3, Vert produces Rom and Ram as idols taking them off Blanc's busy hands. Blanc thanks her for that, since Rom and Ram would have felt dejected, because of Blanc's busyness. Blanc and Vert are quite close, much closer than what the gameplay would show the player. Due to both goddesses being part of the main cast, they have gone through a lot and became very good friends.
