Kotomine Kirei is a priest and antagonist in the Fate franchise, best known among fans for his surprising devotion to mapo tofu, a fiery Sichuan dish he eats with complete seriousness. The gag became a running joke in Fate/stay night and its later adaptations, where his love for the dish contrasts sharply with his role as a manipulator and villain. Online, Fate fans turned the moment into a shorthand meme for deadpan obsession, using the short voice clip in edits, reaction videos and food jokes long after the original scenes aired.
