Luna Sea is a Japanese rock band formed in Kanagawa Prefecture in 1986. Due to the use of makeup and costumes early in their career and their widespread popularity, they are considered one of the most successful and influential bands in the visual kei movement. Throughout the mid-1990s they used significantly less makeup, and after a one-year break in 1997, came back with a more mainstream alternative rock style and toned down their on-stage attire. They disbanded in 2000. In 2003, HMV Japan ranked Luna Sea at number 90 on their list of the 100 most important Japanese pop acts.

Visual kei , abbreviated v-kei , is a category of Japanese musicians that have a strong focus on extravagant stage costumes that originated in Japan during the early 1980s. Koji Dejima of Bounce wrote that visual kei is not a specific sound, but rather it "revolves around the creation of a band's unique worldview and/or stylistic beauty through visual expressions in the form of makeup and fashion". While visual kei bands can be of any music genre, it is generally associated with glam rock, punk rock, and heavy metal.
