The Gender-Flip of Haruhi Suzumiya, often referred to as the Haruhi Genderbend or Rule 63 AU, originated within the early anime fandom on platforms like 2chan and Pixiv. Fans reimagined the iconic SOS Brigade with swapped genders, most notably turning the energetic Haruhi into the handsome Haruhiko and the cynical Kyon into the fan-favorite Kyonko. This meme explores the shift in character dynamics and romantic tension when the roles are reversed, often using high-quality fan illustrations that mimic the original Kyoto Animation style. It remains a staple of anime subculture, used to celebrate the creativity of the 'What If' scenario and the enduring popularity of the franchise.
