Gojo Satoru is the strongest jujutsu sorcerer in all of history. He currently works as a teacher in Tokyo Jujutsu High. He's always filled with confidence due to his power (and looks.) But has an overall silly personality. In this world, Jujustu is not known by just everyone. Not all people can even see curses. So, Gojo isn't known by normal people nor does he tell people about jujutsu, cursed techniques, cursed spirits, etc.
