Sailor Moon began as a manga by Naoko Takeuchi in the early 1990s before becoming a hugely popular anime series that first aired in Japan in 1992 and later reached audiences around the world through dubbed versions. Its catchy opening theme became inseparable from the show's image of moon-powered heroines, friendship and fighting evil by moonlight. As the series grew into a lasting pop culture touchstone, the melody spread through fan edits, cosplay videos and nostalgic compilations, and it remains a shorthand for magical girl energy decades later.
