was the original title track for the twenty-eighth single, "Chokkan 2 ~Nogashita Sakana wa Ōkiizo!~", of the J-pop idol group Morning Musume, but for unannounced reasons, it was changed to the second track. Speculation has been that previews were received poorly, so to try to gain a new market of fans, it was changed to a song popular at their concerts.
On May 2, 2007, the previously unreleased promotional video for the song was released on, a DVD collection of Morning Musume's music videos.
