I have an idea. Instead of them losing their fan base because they haven't done anything, why don't we stay together and do something to inspire them?
What I mean is that, we could gather all the BeForU fans from around the globe and make something to show that they still have a lot of supporters rooting for them. It's a tough work, but maybe it's worth a try.

What do you think?
Well first, I'm going to assume that you mean the last known incarnation of BeForU with the 3 new members and Riyu. It's definitely an admirable idea, but you're going to have to face the fact that the last (and only album) they produced didn't sell too well. So not only would you have to persuade each member, who seem to be doing other things at the moment, but you're also going to have to somehow get their contractors to believe that it'll be worth their money to churn out whatever other music they can make. Also, I'm sure that many BeForU fans are still ambivalent about the member changing, and by now, I'm sure that many have moved on. So getting support right now would be pretty difficult.
But if anything, a more realistic goal may be to first somehow persuade Riyu alone? As far as I know, she's still with Avex, and last we heard, she may still be in the works of another album. However, we all know that news came a long time ago, so she's probably on hiatus with it or something.
