AIKA kinda looks similar to me over the years. Haven't really noticed much of a difference, but maybe you remember her from many years back.
If anything I find that she looks worse when just being out in public. She really likes the makeup game, but I find she makes her eyes look weird on her instagram. That's almost borderline crazy to say that a person looks more exaggerated outside of porn, but then Japanese porn doesn't necessarily try to make the actresses have a look that says "I am blatantly a pornstar" in the more western cliche sense. Though I think western porn has a done a much better job about that in the last 10 years too.
But long story short, I do like AIKA's look regardless.
Yuka I don't know as I don't really think I seek her out. The name doesn't ring a bell immediately. I think you may have brought her up some months back as the actress who was getting back in the game, but you were disappointed due to some of her alterations?
edit: looking at Yuka's filmography, maybe it is. There was a gap between the end of 2016 until mid 2019. I notice she had a video with AIKA after her return. Hmm... maybe I'll check that out.
