Kaori Iida
The album was released at a pivotal and transitional time for the group, as upon its release in December 2004, it was already known that first generation member and group leader Kaori Iida and fourth generation member, Rika Ishikawa, would be leaving the group within three months of each other — Iida to embark on a solo career and Ishikawa to concentrate on her new group V-u-den.
