Kamen Rider Black aired in Japan from 1987 to 1988 as part of Toei's long-running Kamen Rider franchise, following Kotaro Minami after he is transformed into the hero Black. Its ending theme accompanied each episode's credits and became closely linked to the show's more sombre mood, contrasting with the energetic opening. As clips and full episodes circulated online, international fans rediscovered the series through streaming and fan communities, keeping the closing music in use for tributes, retrospectives and nostalgic edits decades later.
