Information
Promise/Star is Japanese R&B-turned-pop star Kumi Koda's 18th single domestic single under the Avex sub-label Rhythm Zone. The single was Kumi's first attempt at a double a-side and was her final single released before her first greatest hits album, Best ~first things~.

The single consisted of the upbeat pop song "Star" and the emotional ballad "Promise," along with their corresponding instrumentals. The CD only edition was of limited release and contained unique cover art, compared to the CD+DVD edition.

"Promise" was used as the ending theme on the TV Asahi show Telechika, while "Star" was used as a promotional campaign for the Nintendo DS game Urusei Yatsura: Endless Summer.

Despite being a double a-side, "Star" only received a short version, the music video only being a minute and a half long. It was speculated that the full version would be released on Best ~first things~, but a complete version was never released.

Packaging
Promise/Star was released in two editions: CD and CD+DVD. Along with the music videos on the DVD, a behind-the-scenes making video was also included.

While the single received two editions, the CD only was of limited release.

"Promise" carried a sad theme of a woman crying at a wedding altar, missing her fiancé, who had died prior to their wedding. In the video, Kumi is donning a wedding dress and veil during the past scenes and a full black ensemble during the mourning present day scenes.

"Star" was more optimistic, with Kumi in front of a starry background. There were no scene changes in "Star," instead only changes in camera angles.
