Demon Slayer’s head writer reveals how cornerstone of Japanese cinema inspired Infinity Castle

Demon Slayer: Kimetsu no Yaiba – Infinity Castle is a tremendous achievement that required an unfathomable amount of work and skill from the team at Japanese anime studio Ufotable. Not only was Infinity Castle a blockbuster hit that showcases anime’s foothold in America, it’s also a highly entertaining story. For Ufotable co-founder and Infinity Castlelead writer Hikaru Kondo, that last part was perhaps the most difficult to pull off — until he remembered a story about the creation of one of Japan’s most revered films, Seven Samurai.
