Moonlight Densetsu, performed by the Japanese group DALI, was the opening theme for the original Sailor Moon anime that began airing in Japan in 1992, based on Naoko Takeuchi's manga. Its bright pop sound helped define the magical girl genre for a generation of viewers, and later English-speaking fans discovered it through dubbed broadcasts, reruns and online clips. Decades later it remains a shorthand for Sailor Moon itself, reused in edits, covers and nostalgic compilations whenever creators want an instant connection to the series.
