Inosuke Hashibira is one of the main fighters in Demon Slayer: Kimetsu no Yaiba, the anime adaptation of Koyoharu Gotouge's manga that began in 2019. Raised by boars and known for his boar mask, dual serrated swords and constant shouting, his screams became a shorthand for unfiltered aggression online. Clips of his yells circulate on TikTok and YouTube as a scream meme for rage, excitement and comic overreaction, long after the original episodes aired.
