The song was written entirely by Shiina, and was then given to Yasutaka Nakata to arrange. Nakata productions for artists such as Ami Suzuki, Perfume or Kyary Pamyu Pamyu generally feature Nakata writing lyrics and music as well. However, Nakata had worked as a co-writer in the past, on singer Meg's albums between 2007 and 2010.
