Nezuko Kamado, the beloved demon sister from the hit anime series Demon Slayer: Kimetsu no Yaiba, became an overnight internet sensation primarily through her 'Smol' form. The meme typically highlights her adorable nature, especially her tiny running animation or the scenes where she peeks out from her wooden box. Fans use these templates to represent innocence, speed, or wholesome reactions to everyday situations. Since her debut in 2019, Nezuko has transcended her origin story to become a symbol of 'must protect' energy across social media, often used in contrast to the dark and violent themes of the series she inhabits.
