I don't understand the question, and don't know what "expresses" are.
The game console is not used for any modification; it's used to play minigames to earn points, that you can then use on the GIMMICK store or the Cafe to buy hints.
Hi, sorry if I didn't explain myself very well. What I meant was that I didn't know how to progress with the video game console; since there were cutscenes, I thought that would trigger a transformation into a "gamer girl," but apparently not. I was also wondering what the point of buying coffee is.
