The song was released as part of Canary CLUB's album ② Eejanaika (②エエジャナイカ) on August 26, 2009 in Japan.

The song was performed live during a promotional concert for Rhythm Heaven, where the audience was asked to take part in the song. It was also performed live in Rhythm Tengoku: The Uta Matsuri+, once to show the new singer Ari~sa (this version being used for Fan Club in the game) and a second time to show the New Arrange Version, arranged by Kaoru Okubo, which was used in Fan Club 2 in Rhythm Heaven Megamix.

While Ari~sa's performance replaced the original in Japanese, the other languages kept their original recordings. The New Arrange Version was also edited in a lower key outside of the Japanese version to match the original arrangement.
