This work is built around the theme of things that never fade, and features songs created in collaboration with four vocalists: Akina, Aitsuki Nakuru, Itsuki Natsume, and Hanatan. Each track is crafted to suit the unique character of its vocalist. The package also comes in a special edition format, combining a 32-page art book and CD in a clear sleeve. A world woven together through illustration and music, delivered to you.
