Blue Bird was released in 2008 by Japanese band Ikimono-gakari and served as the third opening theme for Naruto Shippuden. Its image of a bird flying into a blue sky made the chorus widely recognised beyond the series. Indonesian-language covers later spread through YouTube and TikTok, where local singers translated the lyrics while keeping the original arrangement and emotion. That version stays popular with Indonesian anime communities who grew up with Naruto on television and now reuse the clip for edits and tributes.
