Few other anime series have ever built the sort of hype and anticipation that surrounded Chainsaw Man in the months leading up to its premiere. It's rare that a series creates such noise years before its anime adaptation is even announced, but the original manga by Tatsuki Fujimoto became a sensation during the final stretch of its masterfully crafted Part One. Word spread by mouth and on social media, and even fans who had never before picked up manga rushed to the series to see what the hype was all about.
