Ummmm, NeoIvAn? Check the post above you! It's talking about what that poster is all about!!
Here is some more info thanks to myself and the fabulous Tora.
The Riyu solo song is called "Yamato Nadeshiko Tamashii", and it will be featured on a program called "Anime Shower"! (LOL! Try to find anything about this without finding porn sites! Haha!)
While the Noria solo song, "LOVE LOVE Clutch", will be featured on a program called "Tenshi Ranman". (I haven't been able to find anything about this program either.)
And of course, the upcoming mainstream BeForU single's title is undecided!
I am personally very excited about BeForU having some more mainstream releases! (outside of "true" by Riyu, released by Toshiba-EMI years back)
I will definitely get the preorder, as I understand it, the pre-order comes with that poster you see in the post above this!!
