Tanjiro Kamado is the main character of Demon Slayer: Kimetsu no Yaiba, the manga series that began in 2016 and was adapted into an anime in 2019. Short voice clips of Tanjiro are widely reused in fan edits because his earnest delivery is instantly recognisable to anime viewers. This boom boom version spread as a green screen clip, making it easy to place over other footage. It remains popular for quick meme timing where a spoken cue works better than an actual explosion sound.
