What is an Anime Headcanon?
An anime headcanon is a personal interpretation or belief about an anime character, relationship, or story element that isn't explicitly shown in the manga or anime. Anime headcanons help fans explore character backstories, daily habits, hidden emotions, and "what if" scenarios that the original creators didn't cover. They're a fundamental part of anime fandom culture and are widely shared on platforms like Tumblr, Twitter, AO3 (Archive of Our Own), Wattpad, and TikTok.
