So I have a Korean/Japanese girlfriend and we watched "Sadako vs Kayako" together yesterday. After the movie she started searching for the involved actors in the movie (she always does this) and was especially interested in the one in pic related because she wanted to have this exact underwear.
Now when she went back to her student dorm, she started searching in the internet for it and kept me posted on it. She later told me that she found porn of this actress (I don't know what she defines by porn, but at least a nude) on a Japanese forum.
Sadly, I don't speak Japanese. And I couldn't just ask her for a link because girls get easily offended on such things. So if it really exists, I'm /r/ing nudes / porn of "aimi satsukawa"
no one is going to help you because you're bragging about a girlfriend (allegedly) that 90% of the people on here don't have
and you have all of the info needed to do what you need to do so you can fuck right off
