Kokushibo is Upper Rank One of the Twelve Kizuki in Demon Slayer: Kimetsu no Yaiba, the long running manga and anime created by Koyoharu Gotouge.

His refusal to die defines his final battle, and fans clipped his scream to use as a defiant reaction online. The clip now circulates alongside other dramatic anime power moments like the Mangekyo Sharingan reveal in edits and soundboards.
