High-King

High-King was a unit under Hello! Project, originally to do one single release, "C\C (Cinderella\Complex)" in June 2008, however, in 2009, High-King was revived during the shuffle unit revival period with all five original members along with several other dormant units. Following Ai Takahashi's graduation from Morning Musume and Hello! Project in 2011, High-King did a final performance together at her graduation concert and announced their disbandment.
