## Background and release

"Sparkle" is used in advertisements for the Honda Zest Spark, while "Rule" was used as the international theme song for the 2009 adventure film Dragonball Evolution. "Rule/Sparkle" was released on February 25, 2009 by Avex Trax and Avex Taiwan in three different versions: two different CD editions and a CD and DVD version. Both CD version features two remixes of "Rule" while the first version features two remixes of her single "Green" and the second features two remixes of her single "Days". Akira Toriyama, the creator and manga artist of the Dragon Ball series, was commissioned by Avex Trax to draw an illustration of Hamasaki. It shows the singer wearing the outfit of series' protagonist Son Goku and appears on the DVD version of the single. The song's music video features a piece of choreography patterned after Goku's signature "Kamehameha" attack.
Musically, "Rule" is a "hard" rock song that incorporate harder drum progression and guitar strumming; Mike LaBrie from kanzenshuu.com commented that the composition is "pound harder than they have before with her music". LaBrie also remarked that the lyrical content was rather "self-centered" and "cocky". "Sparkle" is a rock-influenced electronic song that was compared to the works of French musical duo Daft Punk.

## Reception

"Rule/Sparkle" received mixed reviews from most music critics. Victoria Goldenberg from Purple Sky magazine criticized the production of the singles, stating " the singles themselves barely sound like singles. I had to listen to "Sparkle" and "Rule" five times before I started to remember the choruses. That’s far from "Seasons," which stuck with me immediately when I heard it in 2000, got me into Hamasaki’s music, and remains a favorite today." Random J from his online website reviewed Hamasaki's album Party Queen (2012) and compared the composition of the album to the tracks, stating "It makes me appreciate Next level a whole lot more, an album which I cared very little for. I think it's because in my head when I hear the term Party Queen', I think of songs such as "Rule", "Sparkle" and "Rollin'" - all of which throw near enough every up-tempo song on Party queen under a Nozomi bullet train." LaBrie was critical towards "Sparkle" for its repetitive structure and its harsh composition, but was moderately positive towards the production and lyrics of "Rule".
"Rule/Sparkle" charted together and debuted at number one on the Japanese Oricon Singles Chart, becoming Hamasaki's twentieth consecutive single to debut at number-one position since her 2002 single "Free & Easy" and made her the first solo artist and the female artist to have twenty consecutive singles to debut at number-one position. The song was her thirty-second single to go to number one on the Oricon Singles Chart and charted for nine weeks, her lowest spanning single in the charts until her 2010 single "Crossroad". "Rule/Sparkle" was certified gold by the Recording Industry Association of Japan (RIAJ) for shipments of 100,000 units and "Rule" was certified platinum for digital sales of 250,000 units.
