Jujutsu Kaisen is an action-packed fantasy anime with powerful, sinister villains who threaten the heroes with total extinction. While some anime villains scheme world domination or want to get revenge for past wrongs, the Special-Grade Curse known as Mahito dreams even bigger. His stated goal is to destroy all of humanity and allow curses to inhabit the Earth. In Mahito's villainous eyes, curses are superior to human because they are honest and true to themselves, unlike deceptive humans.
