Kick Back was released by Japanese singer songwriter Kenshi Yonezu in October 2022 as the opening theme for the Chainsaw Man anime adaptation. Co arranged with Daiki Tsuneta, the track topped Japanese charts and spread worldwide as the series premiered internationally. Short clips circulated on TikTok, YouTube and anime forums, where fans paired the opening riff with edits, covers and remixes. Its association with Denji and the show's opening sequence keeps it in demand long after the first season aired.
