Jujutsu Kaisen Season 2 has reintroduced Satoru Gojo—the fan-favorite strongest jujutsu sorcerer of his time—in the prime of his youth. In the Hidden Inventory arc flashback, Gojo is nowhere near the omnipotent status he displayed in Season 1 of JJK but is still a second-year student at the Tokyo Metropolitan Curse Technical College. Even so, Gojo is still quite a force to be reckoned with, as evidenced by his exploits in Episode 2. Teenage Gojo isn't a full-fledged sorcerer yet, and his current mission is to highlight the gap between his current age and the adult form that fans are familiar with.
