The release 0f a new Story CD, the first in almost 5 years, was announced yesterday through the Sound Horizon official website. This release will be the third and last volume of the Anniversary Series, which started with The Assorted Horizons and was followed by the Maxi Single Vanishing Starlight.
Surprisingly (or not), this will be the 9th Story CD. The reason behind this decision is still unknown, but we will be awaiting further announcements, such as the title of the album and the singers involved.
For now, you can preorder any of the three versions of the 9th Story CD here:
