Yes, it's possible that people don't feel the need to talk about them, but it's not like there is any discussion here at all, even when they release new music. Fortunately there are other places to discuss them, but you often meet only hardcore fans at these places, so you feel equally stupid, even though I like AAA I don't really know that much about them.
I find it really strange though, that there is not that much of a discussion. For me AAA are the boyband of avex, that also happen to have girls. I know they're not as popular as TVXQ but their sales are increasing constantly, and there are certainly newer and less popular bands around that are in their 10th thread on AHS.
Anyway, I don't really know why I wrote all that...haha.
I only watched the first 2 or 3 episodes of Ghost Friends. It was cute, but I didn't really like it that much. I'm not exactly target audience, too old for that kind of story. Nissy is a great actor, though. Did you watch Love Exposure? Certainly not for everyone, but almost 4 hours of Nissy acting and it's a pretty cool movie.
Speaking of age, Nissy does look so young in that photoshoot. It's amazing, like a little boy, maybe 13 or 14....not like 24.
