Mahoraga comes from Gege Akutami's Jujutsu Kaisen, which began as a manga in 2018 and reached a wider audience with the anime from 2020. As the Divine General of the Ten Shadows Technique, Mahoraga can adapt to any phenomenon, so characters summon it only as a desperate last move. Clips and edits built around calling for its help spread widely during the Shibuya Incident arc, turning the plea into a shorthand online for facing something so unfair that only an unstoppable summon could fix it.
