Kenshi Yonezu’s “IRIS OUT,” the opening theme for Chainsaw Man – The Movie: Reze Arc, has surged to an 83 percent market-implied probability as the frontrunner for Best Anime Song at the 2026 Crunchyroll Anime Awards. Its commanding position stems from sustained chart dominance on the Billboard Japan Hot 100, multiple weeks at No. 1, and strong precursor recognition including Song of the Year nods at the Music Awards Japan and reader-voted honors from Genius Japan. The film’s high visibility and Yonezu’s established industry stature have consolidated trader sentiment around this entry ahead of the May 23 ceremony. Competing tracks such as Lilas Ikuta’s “In Bloom” from The Apothecary Diaries Season 2 and LiSA’s “ReawakeR” from Solo Leveling Season 2 remain in single digits, reflecting narrower streaming momentum and fewer guild or critics’ accolades in the current cycle.
