The single was first announced on
Yasushi Akimoto's
Google+ and the title song premiered live on September 18, 2012, at the AKB48's
rock-paper-scissors tournament at
Nippon Budokan. This is also the first single without ace
Maeda Atsuko, and this is also the first senbatsu participation of
Sakura Miyawaki.
Mayu Watanabe was originally one of the centers, along with
Jurina Matsui, however due to heavy choreography involved in this song,
Yuko Oshima, a more experienced dancer, later replaced Watanabe's center position. It was released in four versions: Type-A, Type-K, Type-B, and Theater Edition. The music video for the title song was directed by
Joseph Kahn, the director of the music video for "
Gingham Check". == Track listing ==
