- The stage play was first announced May 12,2012.
- This stage play was not produced by Gekipro, like most Hello!Project stage plays were (before 2014). It was produced by Drama Base.
- Okamura Rise was originally listed as a participant rather than Tanabe Nanami when the stage play was first announced. However, four days later, Tanabe took over her role. It is believed that this has something to do with her withdrawl.
