IF/Super Dimension/Relationships
CPUs
Neptune
Neptune is the first CPU IF met while IF is the second maker character Neptune met. Despite large differences in personality, she is one of Neptune's closest friends. However, she is serious so if Neptune slacks off, she is going to get it. They have their occasional bickering with weight and body shape but nothing they cannot solve with some competitive gaming!
Noire
Blanc
Vert
In the original Hyperdimension Neptunia, IF worships Vert as her CPU. IF and Vert get along very nicely as a result. Vert tries very hard not to disappoint IF so she hides her boys love games.
Makers
Compa
Compa is IF's childhood friend. They are best friends with very different personality and are the first two to meet Neptune. IF plays the role of a protector to Compa. She is comically obsessed with Compa with different incarnations of IF having pictures of her sleeping, refusing to share Compa with the other makers or wanting her to be an idol to take down Neptune.
Nisa
Gust
5pb.
RED
In the original HDN, IF has a very friendly relationship with RED as a result of IF playing the role of "wifey" for RED.
