The girls are short except for Coco and Botan. Okayu is the shortest among gamers. She maybe chubby but not obese. She can move with high mobility, she just doesn't want to because she's lazy. All of them are able to carry their weight including Polka. The only one who is active physically is Aki (outdoor camping and belly dancing) , Korone(gym rat) and Flare(outdoor camping), Subaru and Nene (nonstop dance lessons). If they all do get 3D projects that means they have to do dance lessons, singing lessons and streams. This will naturally shave a lot of their weight because they will always be dead tired to move. Much like Aqua. If they were fat before, they won't be for long.
