Saint Seiya began as a Japanese manga and anime about young warriors, known as saints, who fight wearing armour inspired by constellations. In Brazil the series was broadcast as Cavaleiros do Zodiaco and became a defining childhood favourite, with its opening theme recognised far beyond anime fans. Clips of that theme later spread through YouTube edits, gaming videos and social media, where its heroic sound instantly signals an epic showdown. Decades later it remains a shorthand for nostalgia, courage and over-the-top drama.
