Ok, I didn't really think that the characters go through an age progression in their transformation into their Goddess forms other than Neptune, Plutia, and Piishe due to the noticeable difference in size. However, Ryse pointed out in the Neptune's AP thread that Noire's transformation includes breast expansion as well.
I tried rewatching her transformation again in slow speed and did notice that there is a very slight expansion during the scene where her breasts jiggle once. However, her breasts' size before and after the transformation is hard to tell apart.
What do you guys think? I haven't played the game, so I am not sure if all of the casts' goddess transformations are supposed to be age progression or not.
