>>107434056She's just not a very sexual person. I don't know if that's what you consider a prude, she's middle of the road for EN. Same as Ina, Ame, ERB, Mumei, CC, etc.
I guess some members are slightly more sexual, Kiara and Nerissa for example. But overall EN is pretty tame. We don't have anyone on the same level as Noel or Okayu.
If by stuck up you mean the outfitschizo narrative that she hated her model for having big boobs, it was never true.
