Trivia

 * The music video was filmed after the graduations of Mana Tissue Fold and Hikicomo Ricca and instead uses a recording that includes the vocals of Tanaka Iroha, Chan Richan, and Koharu Nushi. However, because it was released after Tanaka's withdrawal from the group, it censors out her parts in the video.
