Gojo Satoru is first introduced in Jujutsu Kaisen as an overwhelmingly powerful sorcerer—untouchable in both strength and attitude. His arrogance is undeniable, yet his charisma makes him one of the most compelling characters in the series.
But Gojo wasn’t always the composed, confident mentor seen in the present timeline. To truly understand his evolution, we must examine the pivotal Hidden Inventory Arc, where he and his best friend, Suguru Geto, faced a tragedy that changed them forever. They were once inseparable, but after this mission, they walked opposing paths—Gojo toward nurturing the next generation, Geto toward destruction. Their divergence wasn’t just personal; it was a direct consequence of Riko Amanai’s death and the realization that the jujutsu world was far more broken than they had ever imagined.
Gojo’s Mindset Before the Hidden Inventory Arc
Strength Above All
In his youth, Gojo’s ideology was simple—sorcerers exist to do their job. With his overwhelming talent, he viewed himself and Geto as “the strongest,” two prodigies destined to complete missions without questioning the system. There was no deep ideological stance, no personal investment in the future of jujutsu society. He was simply doing what he had been told, excelling beyond anyone else.
“I’m tired of being careful of weak people.”

While Geto had strong moral convictions about protecting the weak, Gojo saw power as the ultimate deciding factor. In his mind, the strong dictated reality, and the weak either needed protection or were irrelevant. His arrogance went unchecked because, up until that point, he had never been forced to truly confront his own limitations. But that was about to change.
How the Star Plasma Mission Changed Gojo’s Outlook
The Hidden Inventory Arc follows Gojo and Geto on a mission to escort Riko Amanai to merge with Master Tengen. On paper, it was straightforward. But reality was far crueler.
Gojo, typically indifferent to those outside his inner circle, found himself growing fond of Riko. Despite their constant bickering, she became more than just a mission—she was a friend. When she was suddenly killed in front of him by Toji Fushiguro, Gojo’s worldview shattered.
For the first time, he felt true failure—not just in his mission, but in his belief that power alone was enough. His immediate response was unfiltered rage. In the wake of Riko’s death, Gojo unlocked his full potential, achieving near-invincibility by mastering the Limitless and Awakening the Six Eyes. But while his power reached new heights, he was forced to confront a painful truth—raw strength couldn’t undo what had happened.
Adding to the devastation, the Time Vessel Association celebrated Riko’s death, viewing it as a righteous victory. This moment cracked something inside both Gojo and Geto, but their responses would take them down drastically different paths.
Geto’s Breaking Point: A New Perspective on Sorcerers and the Weak
Geto had always believed that sorcerers existed to protect non-sorcerers, even if he saw them as inferior. But Hidden Inventory forced him to question everything.
“Society should protect the weak and keep the strong in check. You see, Satoru, jujutsu exists to protect non-jujutsu users.”
— Geto in Hidden Inventory
But what happens when the weak actively work against those protecting them? The Time Vessel Association had blindly opposed the jujutsu system without understanding its complexities. Their ignorance wasn’t just frustrating—it was dangerous.
This seed of doubt grew into something more sinister when Geto encountered Mimiko and Nanako, two young sorcerers who had been brutally abused by the very people he had sworn to protect. This was his breaking point.
To Geto, non-sorcerers weren’t just weak; they were obstacles. They refused to understand the sacrifices sorcerers made for them. Worse, they actively hindered those who were trying to keep them safe. If the jujutsu world was built on protecting the weak, but the weak weren’t worth saving, then what was the point?
“No matter what anyone says, I really hate those monkeys. But I never held any hatred for those in Jujutsu High.”

By the time Gojo realized what was happening, it was too late. The friend who had once been his moral compass had decided to destroy the very world they once protected. Their final conversation was one of painful realization—Geto was gone, and Gojo couldn’t bring him back.
Gojo’s Response to Geto’s Fall: A Shift in Purpose
Faced with Geto’s descent into darkness, Gojo made a choice. He wouldn’t follow. Instead, he would forge a new path—one that sought to fix the system from within.
For the first time, he understood that strength alone wasn’t enough. He had to invest in the future, in the next generation of sorcerers. If he could cultivate strong, intelligent allies, maybe they could dismantle the corrupt structures of jujutsu society and create a world where tragedies like Riko’s death and Geto’s downfall wouldn’t happen again.
“I’m gonna reset this crappy jujutsu world. It’d be easy to kill everyone who’s in charge. But someone else would just take their place. Nothing would change. And it’s not as if people approve of massacres anyway… So that’s why I’m turning to education. I need strong and intelligent allies. I need to foster them.”
— Gojo
This was the birth of Gojo the teacher. No longer just the strongest sorcerer, he became a mentor determined to cultivate the next generation—not just as fighters, but as free thinkers who wouldn’t be shackled by the mistakes of the past.
His arrogance never faded, but it evolved. Instead of being a weapon for the jujutsu world, Gojo sought to reshape it. Instead of simply proving he was the strongest, he wanted to create students who could stand beside him.
Conclusion: Two Paths, One Tragedy
The Hidden Inventory Arc defined both Gojo and Geto, pushing them toward opposite destinies. Gojo emerged stronger, determined to change the jujutsu world through education and leadership. Geto, broken by disillusionment, sought to burn the system to the ground.
Their tragedy is that they were both right—and both wrong. Gojo saw potential in the future, while Geto saw nothing but corruption. But in the end, neither of them could truly change the world in the way they wanted.
The fallout of Hidden Inventory echoes throughout Jujutsu Kaisen, influencing every decision Gojo makes as a teacher and every action Geto takes as an antagonist. Their rivalry isn’t just about power—it’s about ideology, about two men who once stood together but ultimately found themselves on opposite sides of an unfixable world.
