Basically Quest is Campaign. You are basically walking through the stage area until you are finished with one(according to Miwabar) and move on to the next until you are finished fighting the boss 3 times which is the feature girl.

Along the way in each area, you will get Friend Points, free N idols to join you and meet a Rival. This Rival is actually battle encounter in form of Scouting. You basically have to persuade her to leave you alone(because this Rival is unique for each Stages as you will meet her in each areas, her level increases as you traversed through area 1-9).

Your sig, that happened also my first time playing it but that is probably due to Miwako haven't finished put on her wig(slow loading).

It works for me. Although, it is kinda lagging.

Seems to be temporary. I'm back online as well.
