Oh, it's an album which contains the character songs of the seven Edel Rose guys. It was initially released in August 30, but it was published on either October or November on the same year though. (I may be wrong but I know it's quite late.)

Dw, as soon as the hikarinoakari staff saw that request, it will be published. ^^
