Going back to compare my Koikatsu Asuna to Fujino's, I noticed her clothing has actually been changing. At the start, she used to have full length pantyhose on under her school uniform and now she has thigh highs or high socks. The jacket and skirt design and colors also changed, but didn't get noticibly shorter. I think the neck tie used to be a ribbon bow.
But yeah, I'd love to see her do some IRL cosplay to really change up how she looks for a scene, and get caught on some public date with Inoda. "No way that's Asuna, she'd never dress like that" stuff. Or even some uncensored PoV blowjob video from Inoda's phone, but nobody recognises the 'new slut'.
