The Fearsome Womb Arc: Where Jujutsu Kaisen Begins

The Fearsome Womb Arc (呪胎戴天編) is the first story arc in Gege Akutami’s Jujutsu Kaisen. It runs from Chapter 1 to Chapter 18 and covers Yuji Itadori’s entry into the jujutsu world — from his grandfather’s death to his enrollment at Tokyo Jujutsu High and his first mission with Megumi Fushiguro and Nobara Kugisaki.

It is not a slow start. By Chapter 4, Yuji has swallowed a cursed finger, become the vessel for the King of Curses, and been sentenced to death.

Arc Profile

What Happens in the Fearsome Womb Arc?

The Fearsome Womb Arc introduces Yuji Itadori, establishes the jujutsu world’s rules and hierarchy, and ends with Yuji alive — temporarily — as Sukuna’s vessel under a death sentence.

Yuji is a physically exceptional high schooler with no connection to jujutsu until Megumi Fushiguro arrives at his school tracking a cursed object — one of Ryomen Sukuna’s twenty fingers. Yuji’s friends in the Occult Research Club have already unsealed it. Curses swarm the building.

When Megumi is overwhelmed, Yuji swallows the finger. Sukuna awakens. The curses are obliterated. Yuji wrestles back control of his own body — something that should not be possible given Sukuna’s power — and survives.

Gojo arrives, assesses Yuji, and presents the jujutsu higher-ups with a proposition: rather than executing Yuji immediately, let him consume all twenty of Sukuna’s fingers before dying. Every finger collected is a finger that cannot fall into enemy hands. The higher-ups agree, reluctantly.

Yuji enrolls at Tokyo Jujutsu High. He meets Nobara Kugisaki. The three first-years are sent on their first mission together — a juvenile detention centre in West Tokyo where a cursed womb has spawned, potentially carrying a Special Grade curse inside it.

The mission goes badly. The cursed womb births a Special Grade curse. The three first-years are genuinely outmatched. Yuji tries to invoke Sukuna to fight for them — Sukuna instead takes full control and tears the Special Grade apart with his Domain Expansion, Malevolent Shrine. Sukuna uses the opportunity to rip out Yuji’s heart.

With no heart, Yuji cannot take back control. Sukuna forces a binding vow — in exchange for reviving Yuji, Sukuna can take over Yuji’s body at any time for one minute without Yuji being able to fight back. Yuji, having no real choice, agrees. The terms are sealed. Yuji comes back.

The arc ends with Yuji alive, enrolled, and carrying a deal he made while dying that will have consequences he cannot fully see yet.

Read this arc from Chapter 1 through Chapter 16.

What Does This Arc Set Up?

The binding vow between Yuji and Sukuna is the arc’s most consequential detail. It is easy to overlook in the moment — a survival mechanism in a desperate situation. By the time the Shibuya Incident arrives, that one-minute clause becomes the tool Kenjaku uses to detonate the entire arc’s catastrophe.

The arc also establishes Yuji’s core philosophy — giving people a proper death, inherited from his grandfather’s dying words. Every moral conflict Yuji faces across the entire manga runs back to this arc.

Megumi’s decision to save Yuji at the school also plants a seed. Megumi chose to save someone whose death might have been the safer outcome. That choice, and what it means, becomes one of the manga’s longest-running questions.

What Makes This Arc Worth Reading?

Most shonen series spend their opening arcs on slow world-building. Jujutsu Kaisen does not. By Chapter 4, Sukuna is awake, Yuji is sentenced to death, and the tone of the entire series is already established. Death is real here. The institution is already morally compromised. The protagonist is already living on borrowed time.

The arc is short — 18 chapters — and efficient. It respects the reader’s time and pays off almost immediately.
