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?

Is there any correlation between the CPU and CPU candidates' oppai sizes like there is with KanColle?


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](http://pastebin.com/eg3qSyMR) a spreadsheetable list of some of the
character's bust sizes for any other answer's _research_.

I don't believe there is an official reason for why their bust sizes varies.
However, there is a correlation to the CPU bust sizes and the targeted
demographic of their respective consoles or at least the kind of games
associated with the console.

For example, [the target demographic for the Wii is
"everyone."](https://en.wikipedia.org/wiki/Wii?oldformat=true#Demographic)
This means that the games for the console have to be playable for kids. It has
to be family friendly. Nintendo's collection of games, such as Pokemon and
Mario, are also family-friendly. This explains why Rom and Ram are kids
themselves and why Blanc is an A cup size. They are shown off as much younger
than the other goddesses.

For Noire, [the target demographic is a "younger
audience,"](http://www.gamespot.com/articles/ps3-to-target-a-slightly-younger-
demographic/1100-6347076/) or at least it was years after its original
release. This explains why she's in the middle of sort. Plus, the top games
for the consoles include mature games such as Call of Duty and more family-
friendly games such as Little Big Planet.

For Vert, [because the top-selling games feature more mature games such as
Gears of War or Halo](http://www.wikiwand.com/en/List_of_best-
selling_Xbox_360_video_games), it makes sense why she has the biggest bust.
The games are for a more older audience and so it makes sense that her bust is
more matured than the others'.

I can't explain why Neptune's bust is the way they are as the console she is
based on is fictional. It could be that the dramatic increase in bust size
indicates how her console's demographic would vary.

This same theory doesn't hold well for the characters based on publishers and
developers, however. IF has made games not suitable for everyone and she has
an A cup size. Perhaps their bust size is irrelevant as their characters are
based off the characters from the games published or developed by their
respective company.

The original 4 CPU's cup sizes are likely based on RAM sizes for their
respective consoles.

Xbox 360 had 512MB of unified ram, while PS3 had 256 each of video and system
ram (often giving the false impression to gamers of "half as much as Xbox"),
Wii had a relatively pitiful 88MB ram. Neptune...doesn't exist as a console so
it's hard to say here.

So, have F/G cups for Vert/Green Heart (the most), C/C cups for Noire/Black
Heart ("half" of Xbox), and A/A cups for Blanc/White Heart (almost nothing
compared to Xbox). We have A/E for Neptune who...doesn't have anything to map
to. All cup size info taken from the measurements in the HDN1 visual guide.

After the first game cup size doesn't correlate to anything in particular
beyond character stereotypes (cute "loli" plutia vs big "sexy dominatrix" iris
heart). The series' interpretations of console -> character has changed a lot
over the years (see the change from French color names to...fairly random
names for the candidates to direct planet names for the non-Nepgear Planeptune
candidates).

Cupsize change isn't a constant matter either. Only Neptune, Plutia and Peashy
get significantly larger (Peashy seems to be an entirely gaming-unrelated
joke, "the smallest one becomes the biggest"), Vert, Blanc and Uzume get
noticeably but not impressively larger, Noire and Nepgear stay about the same,
and Uni actually shrinks (a reference to the PSP Slim in all likelihood). Cup
size change seems basically random and was probably the designer (Tsunako's)
preference, especially beyond the first 4 CPUs..
