Didn't know she had a sister. So her surname is Horiguchi?
That's the thing that always gets me about the AV idols in Ebisu too, because personally, I love them, some more so than others, but they're all beautiful and I like to think I've seen enough of them to know what their personalities are like. But really, I don't even know their real names. Akiho Yoshizawa could well be called Megumi Tanaka in real life. Yuma Asami could be Sayaka Takahashi. It's an odd dynamic, it would take me a while to get used to their real name if I knew them on a personal level. Like, others in the group are BFF's (e.g. Aino & Jessica) but do they even know each others real names or even if they did, do they even use them?
