It has been announced that KAT-TUN will sing the song that will be the theme song to the upcoming drama Yokai Ningen Bemu that stars Kamenashi Kazuya. The song will be titled Birth.
Also for the drama the first photos of the main cast in their yokai forms have come out and it looks like Kame will be donning a silver wig for the role.

Honestly I can't see this song not becoming a single, especially with this kind of tie-in. Though it does seem like KAT-TUN are long overdue for a new album.
