The Gojo's Past Arc is the fifth arc in Gege Akutami's Jujutsu Kaisen. In the anime adaptation, the arc is referred as Hidden Inventory / Premature Death Arc. It follows Satoru Gojo and Suguru Geto during the year 2006, when they were second-year students at Tokyo Jujutsu High. During the arc, they are assigned to escort the Star Plasma Vessel to Master Tengen as curse user groups conspire against them.

Gojo Satoru and Suguru Geto started as close friends, even being the "strongest duo" at Tokyo Jujutsu High. Their friendship evolved into a strong bond, as seen in events like their rescue of Mimiko. However, their diverging paths led to a dramatic shift, with Geto eventually becoming a powerful antagonist and Gojo, though initially saddened, turning into a powerful sorcerer.
