For those of you who didn't see Manyuu Hikenchou fan art from me coming, you need to take a good look at my gallery (as well as "My favorite girls" list).

As it stands, Chifusa is probably the main expansion related girl on TV, only because it's built in as a character mechanic (that might just be her actual bra size for half of the anime). I may be wrong of course, and if so, please link me to other girls like this.
