Jujutsu Kaisen does a very clear and concise job of telling who the most powerful characters are right at the start. This ends up setting an amazing framework as well as a very easy-to-define power hierarchy of the world. Since his introduction to the series, Gojo has been notorious within Jujutsu society as being a sorcerer so incredibly powerful that he is on an entirely separate level from even the strongest grades of sorcerers.
