---To be the "White Girl", that is my purpose.
While being a battle game, its original world view is also a special feature.
AI girls gain emotions as "color", and try to become a human being. As they gain various emotions, their R, G and B status change. The girls' aim is to make all those three status 255, which is a color called "white". To be the "White Girl" is the goal for players, and it also is the goal of world view.
