Fans often mistake the massive floating fortress setup for the final saga, but the short answer is no. The Infinity Castle sequence functions as a massive, high-stakes battleground within the broader final conflict, while the actual concluding storyline of Gege Akutami's manga series is the Shinjuku Showdown arc. Understanding how these structural divisions work helps clarify the trajectory of the series right up to its final chapters.
The narrative transition from the Culling Game into the final blocks of the story confused many readers tracking weekly releases. To untangle this misconception, we need to look at how Gege Akutami structured the final phase of Jujutsu Kaisen, why the Infinity Castle gained such a reputation, and what actually closed out the manga.
The Structure of the Final Saga
Jujutsu Kaisen doesn't operate on isolated, short arcs once it passes the Shibuya Incident. Instead, the narrative merges into a sprawling final saga that spans multiple operational phases.
The final saga encompasses: Related analysis on this trend has been shared by BBC.
- The Culling Game fallout and military intervention sub-plots.
- The preparation and infiltration phase inside the Infinity Castle (technically part of the overarching Shinjuku / final confrontation setup).
- The direct, all-out war against Ryomen Sukuna in the Shinjuku Showdown arc (Chapters 222 through 271), which serves as the definitive final block of the manga.
Because the fights inside the cursed domain of the Infinity Castle bled directly into the surface-level clashes in Shinjuku, fans frequently blur the lines between the two. However, official volume releases and author commentary separate the massive gauntlet against Kenjaku and Sukuna into distinct tactical phases, culminating officially in Shinjuku.
Why Readers Think the Infinity Castle is the Finale
Several distinct narrative markers make the Infinity Castle feel like a traditional "final dungeon" crawl seen in other Shonen titles:
- The Final Boss Gauntlet: Characters split up to face their ultimate matchups. Major figures like Yuji Itadori, Yuta Okkotsu, Maki Zenin, and Fumihiko Takaba confront heavy hitters in a confined, maze-like space controlled by Kenjaku and Uraume.
- The Structural Parallel: Much like iconic final arcs in peer series—such as Demon Slayer's Infinity Castle—the setting forces isolated, high-fatigue duels where every character pushes past their physical limits.
- High Psychological Weight: Long-standing character arcs converge here, forcing readers to assume that whoever enters the castle may not walk out.
Despite these tropes, the action inside the castle acts as the runway for the ultimate war. The plot shifts dramatically once the survivors break out of the domain to face Sukuna at his full power in the ruined streets of Shinjuku.
How the Shinjuku Showdown Concludes the Story
The Shinjuku Showdown arc is where the narrative threads snap. Running from Chapter 222 until the manga's conclusion in Chapter 271, this stretch drops all pretense of tactical colony navigation.
Instead, it presents a continuous, multi-stage boss battle against the King of Curses. Every surviving sorcerer steps onto the battlefield in a relay format. The pacing shifts away from complex domain rules and cursed energy mechanics toward raw attrition, domain clashes, and emotional resolutions, particularly between Yuji and Sukuna.

Common Misconceptions About JJK Arcs
Assuming Every Sub-Battle is a Separate Arc
Readers often label every colony in the Culling Game or every tier of the castle fight as its own standalone arc. In reality, the narrative is split into major macro-sagas. The Culling Game and the final showdown form the massive back half of the entire story.
Confusing Anime Seasons with Manga Arc Divisions
Anime viewers face a different pacing rhythm. Studios adapt the source material in chunks, meaning anime-only fans often use season boundaries to define story beats rather than the official manga volume demarcations.
