Is there any correlation between the CPU and CPU candidates' oppai sizes like there is with KanColle? Hyperdimension Neptunia is an anime that is based on the console war. Its characters are based on the game consoles, namely, Sony Playstation, Microsoft XBox, Nintendo Wii, and the scrapped Sega Neptune.

Now, moving on to Kantai Collection for a while. Like Hyperdimension Neptunia, KanColle is based on real thing. Whereas Hyperdimension Neptunia is based on consoles, KanColle is based on warships. In Kantai Collection, there is a correlation between the size of the girl's oppai and the ship's displacement as shown in the following chart taken from its Wikia page.



Now, as we know, the CPU and CPU candidates in Hyperdimension Neptunia, all has varying oppai dimension. Question is, is there any correlationship between the oppai's dimension and the based console's attribute like KanColle has?
I don't think there's a correlation, based on the fact that bust sizes change when in HDD form. Sometimes dramatically. Neptunia herself upgrades from a modest A to an E cup when she transforms into Purple Heart.

That being said, I don't know much about the series as I'm only playing the first game.

Maybe someone else has more knowledge than me and can also answer. Here's a spreadsheetable list of some of the character's bust sizes for any other answer's research.
