Jujutsu Kaisen, CHAPTER 15

Jujutsu Kaisen Chapter 15 Summary

“Domain Expansion” – Gojo’s Power on Full Display

Welcome to another explosive breakdown of the Jujutsu Kaisen manga!
In Chapter 15, we dive headfirst into a high-stakes lesson between master and student as Satoru Gojo shows Yuji Itadori the terrifying power behind Domain Expansion. If you’ve ever wondered why Gojo is hyped as the strongest, this chapter spells it out—literally. Let’s break down the story, characters, and action that make this installment so unforgettable.

🔥 A Surprise Training Session with Gojo Sensei

Movie Time? Not for Long

Chapter 15 kicks off with a chill scene: Yuji Itadori relaxing and watching movies at Jujutsu High. But the calm doesn’t last. Gojo Satoru swoops in unexpectedly to check in on his student’s cursed energy control—and he’s impressed. Yuji manages to keep a cursed corpse asleep through sheer energy regulation, even during Gojo’s flashy arrival.

Gojo, always thinking two steps ahead, mentally decides it’s time to increase the difficulty for Yuji. And just like that, the real lesson begins.

🌋 Jogo’s Domain Expansion: Coffin of the Iron Mountain

Enter the Volcano

In a sudden shift, Gojo teleports Yuji straight into the middle of his battle with Jogo, one of the most fearsome cursed spirits so far. Yuji, still new to real combat, is understandably shaken. After all, Jogo is no pushover—he’s literally a walking volcano.

When Jogo recognizes Yuji as Sukuna’s vessel, he assumes Gojo is using the boy as a human shield. Gojo, cool and collected, brushes it off: “It’s just a lesson.” Naturally, that infuriates Jogo.

🗣 “Stop underestimating me!” Jogo roars, quite literally losing his head in anger.

Jogo responds by unleashing his Domain Expansion—Coffin of the Iron Mountain. The surroundings morph into a hellish volcanic chamber, where molten attacks now ignore Gojo’s Infinity defense.

This is where the Jujutsu Kaisen manga really starts to flesh out one of its most iconic techniques: Domain Expansion—a powerful sorcery where cursed energy forms a sealed arena that guarantees hits from its user.

Yuji’s jaw drops. So does ours.

🌌 Gojo Unleashes His Own Domain: Unlimited Void

From Fire to Infinity

Just as it looks like things might get serious for Gojo, he flips the script. With a calm gesture, Gojo removes his blindfold (yes, that moment), and summons his own domain: Unlimited Void.

The transition is jarring—from scorching lava to an endless realm of infinite information. Time slows. Sensory overload kicks in. Jogo, once so confident, is paralyzed by the overwhelming experience.

This is the Immeasurable Void. No flames. No attacks. Just a flood of everything—sight, thought, feeling—poured into Jogo until he can no longer function.

Gojo doesn’t kill him right away though. Instead, he takes the opportunity to interrogate the cursed spirit, decapitating him mid-lesson to ask: “Who sent the assassin?”

Yuji, watching all of this unfold, comes to a stunning realization:

His sensei really is the strongest.

🧠 Behind the Scenes: Villains in the Shadows

While Gojo makes quick work of Jogo, Pseudo-Geto and Hanami watch from a nearby cliff. They’re weighing their options—rescue Jogo or stay put? It’s a subtle moment, but it adds tension. Bigger plans are clearly in motion.

🧐 Final Thoughts: Why This Chapter Matters

This chapter isn’t just a display of flashy powers—it’s a turning point in how we view both Gojo and the jujutsu world. Here’s what makes Chapter 15 essential reading:

• We get a proper breakdown of Domain Expansion—a mechanic that plays a massive role in later arcs.
• Gojo’s power isn’t just told, it’s shown. No more “he’s the strongest” without proof. Now we feel it.
• Yuji’s growth is visible. From movie night to standing in a Domain battle—he’s evolving.
