The way "import" genre ARTPGs work is that players are provided with a paperdoll base to color (called the import) that provides all the lineart, basic fills and usually background. When you're done with it, this import becomes your character's official reference image. It's on you to color it according to the rules, but this both standardizes what the game's reference images and also saves players a lot of time/effort: you don't have to come up with a good reference pose and get the lines all nice and fill it in so there's no random holes or stray pixels off in space. All those steps are complete when you show up, all that's left is Advanced Coloring Book Time.
Somehat paradoxically, these games also offer the option to customize the import by drawing your own lines/fills. This tends to have a lot of rules (you can only change a certain % of the lines, you can/can't draw XYZ, etc) and also undoes a lot of the aforementioned time/effort-saving. But it lets you make your muppet look SPECIALER, so it's wildly popular. I used to claim I couldn't see the point, but...
I wasn't going to let my girl live like that. Default wasn't good enough for her. Now I'm hooked. Default horns look stupid? Fur not fluffy enough? Got a better head shape I'd rather draw? Just call Lineart Redraw!
Anyways Mahriti is my most gratuitously fluffy poof to date, but I'm thinking about how my flower princess could be even more of a furball. Maybe run the fluff all the way up to her head....
