Plot Summary

Opening Flashback & Setup

The episode begins with a flashback: Yuji Itadori in a hospital setting, his grandfather urging him to “help others”—a quiet but powerful setup that contrasts sharply with the chaos to follow.

The scene then shifts to a devastated Tokyo district, where Yuji’s body is under the control of Ryomen Sukuna. The emerging crisis centers on Megumi Fushiguro, severely wounded and cornered by the curse-user Haruta Shigemo.

Megumi’s Summoning & Mahoraga’s Rise

Despite his injuries, Megumi resorts to a desperate gambit: he summons the shikigami Mahoraga, a being that no sorcerer has ever successfully subjugated. The ritual is fraught with peril—Megumi accepts that his survival is unlikely. Haruta taunts him as Mahoraga lashes out.

Mahoraga immediately exhibits staggering power: it adapts reflexively to techniques, manipulates the environment as a weapon, and turns the battle into a city-scale catastrophe.

Sukuna’s Intervention

Just as things seem hopeless for Megumi, Sukuna intervenes—not out of altruism, but because Megumi’s life serves his own purposes. Sukuna confronts Mahoraga in a destructive battle that rips through train cars, buildings, and the cityscape at large.

In the climax, Sukuna deploys his domain-expansion technique, “Malevolent Shrine,” obliterating Mahoraga with an arrow-shaped strike. His victory is chilling in its finality.

Yuji’s Awakening & Aftermath

After Sukuna leaves, Yuji regains control of his body. He is confronted with the devastation wrought while his own body was used as a vessel—he vomits at the sight and is overwhelmed by guilt.

Meanwhile, Kento Nanami, battered but alive, walks through a destroyed subway station, underscoring the human cost of the battle.
