Shinobu Kocho is the Insect Hashira in Demon Slayer: Kimetsu no Yaiba, the manga by Koyoharu Gotouge that ran from 2016 to 2020 and the ufotable anime that premiered in 2019. Voiced in Japanese by Saori Hayami, the character is known for her constant smile and soft, teasing way of speaking, even in battle. Short clips of her laugh were cut from anime scenes and shared on soundboards and social media, where Demon Slayer fans and meme editors reuse it as a quick, recognisable reaction for playful mockery.
