Warning: Spoilers For Jujutsu Kaisen Season 2Jujutsu Kaisen's Satoru Gojo is unquestionably the strongest sorcerer that jujutsu society has ever seen. However, like any other character in an action anime, Gojo's strength is the result of rigorous training and hands-on experiences. The first five episodes of Jujutsu Kaisen's second season, the "Hidden Inventory Arc," reveal Gojo's past and the critical events that have shaped him. Gojo's past is rife with trauma and conflict, but one particular enemy is responsible for young Gojo's major power boost.
