I see bits of it here and there, in different parts of her face (some of the eyes, part of the smile, etc). I think it helps that I had photos of her (with her pixie cut) and Karin next to one another for an hour or so when I was putting together my last fantasy costume set.
While I'm here I might as well say that I've always thought Kumai looks so much like Yossie. I think that's why Kumai was my favorite when I was introduced to Berryz.
