BLEACH: Thousand-Year Blood War Part 4 — The Calamity premiered on July 25, 2026, and it’s the one fans have waited over a decade for: the final stretch of the anime, adapting the manga’s climactic chapters and closing out Ichigo Kurosaki’s story for good. Here’s the confirmed release schedule, where to watch, what the story covers, and everything else locked in so far — no rumors, just what Hulu, Disney+, and the production team have actually announced.

What Is The Calamity, and Why Is It the Final Part?

The Calamity is the fourth and final cour of BLEACH: Thousand-Year Blood War, the anime adaptation covering the manga’s last arc. It picks up immediately after Part 3 (The Conflict) left off, with the Soul Society’s war against Yhwach and the Wandenreich reaching its endgame. Series creator Tite Kubo has been directly involved in expanding this final stretch, confirming that The Calamity includes significantly more original, anime-exclusive material than any previous part — a deliberate effort to give the ending room to breathe after the manga’s own finale was famously rushed due to space constraints in Weekly Shonen Jump.

Release Schedule: When New Episodes Drop

The Calamity runs for 10 episodes, releasing weekly. Episode 1 premiered July 25, 2026, with new episodes arriving every Saturday at 7:30 AM PT / 10:30 AM ET (3:30 PM BST for UK viewers). Episode 2 is confirmed for August 1. Notably, the first three episodes received an early theatrical release in US cinemas before the streaming premiere — a first for this adaptation and a sign of how much weight the production is putting behind the finale.

Where to Watch

The Calamity streams exclusively on Hulu in the United States, with Disney+ handling international distribution. This matches the pattern set by earlier BLEACH: Thousand-Year Blood War parts, so if you’ve been following the series so far, no new subscription is needed.

The Story: Ichigo vs. Yhwach’s Final Battle

The Calamity adapts manga chapters 664 through 686 — the chapters that bring BLEACH’s main story to a close. The central thread is the long-awaited final clash between Ichigo Kurosaki and Yhwach, who now wields the Soul King’s near-omnipotent power after orchestrating his death. Ichigo teams up with Orihime Inoue and Yasutora “Chad” Sado to bring him down, while Yoruichi Shihoin faces off against Askin Nakk Le Vaar elsewhere in the fight. Uryu Ishida, whose loyalties were left deliberately ambiguous through most of the Wandenreich arc, gets his own reckoning in a direct confrontation with Haschwalth — the anime-original material is reportedly used here specifically to give Uryu’s arc the space the manga never had.

Quick Recap: Where Part 3 Left Off

Part 3, The Conflict, ended with the Soul Society reeling from Yhwach’s assault on the Soul King Palace and his subsequent acquisition of the Soul King’s power — effectively making him unkillable by conventional means. The Gotei 13 captains had each been forced into increasingly desperate one-on-one fights against the Wandenreich’s Sternritter, several of which ended in serious losses. Uryu Ishida’s true allegiance was left deliberately unresolved: he’d aligned himself with Yhwach as the Wandenreich’s “A” candidate, but his motivations were never fully explained on screen. That unresolved thread is exactly what The Calamity picks up first.

Opening and Ending Themes

The Calamity’s opening theme is “I-BULL”, performed by jo0ji, and the ending theme is “Rasen”, performed by 9Lana. Kubo has said he personally listened to and selected every theme song used across all four parts of Thousand-Year Blood War, from the demo stage onward, specifically to introduce viewers to newer Japanese artists rather than leaning on established names.

Cast and Staff Returning for the Finale

The finale keeps the cast and crew that’s carried the adaptation since Part 1. Returning voice actors include Masakazu Morita as Ichigo Kurosaki, Noriaki Sugiyama as Uryu Ishida, Yuki Matsuoka as Orihime Inoue, and Hiroki Yasumoto as Chad. Behind the camera, Hikaru Murata directs, with Tomohisa Taguchi continuing as chief series director and co-writing series composition alongside Masaki Hiramatsu. Masashi Kudo returns as character designer, and composer Shiro Sagisu — who has scored BLEACH since the original 2004 anime — handles the music. Animation comes from Pierrot Films, the rebranded second studio under Pierrot that has produced the entire Thousand-Year Blood War adaptation.

How Much of the Manga Does It Actually Cover?

Chapters 664–686 make up the manga’s final act, but The Calamity isn’t a straight panel-for-panel adaptation. Because Kubo has confirmed heavy anime-original expansion in this part specifically, several scenes, side character moments, and transitions that were compressed or skipped in the manga’s rushed ending are being restored or newly animated. If you’ve read the manga and remember the ending feeling abrupt, that’s precisely the gap this final cour is built to fill.

This isn’t the first time the Thousand-Year Blood War anime has expanded on the source material rather than compressing it — Part 3 (The Conflict) already added extended fight choreography and character beats not present in the manga panels. The Calamity is the largest expansion of the four, which is part of why a 10-episode cour is covering roughly 22 chapters instead of the far higher chapter-per-episode ratio earlier parts used.

Why the Theatrical Release Matters

Giving the first three episodes an early theatrical run in US cinemas before they hit Hulu is a meaningful signal about how the production sees this final cour. Streaming anime rarely gets a theatrical window at all, let alone for episodes that will be available at home within weeks — it’s typically reserved for franchises the studio and distributor expect to draw crowds on the big screen regardless. For a series that’s been building toward this exact confrontation since 2004, treating the opening episodes as an event rather than a standard weekly drop fits the moment.

Should You Rewatch Before Starting The Calamity?

If it’s been a while since Part 3 (The Conflict), a quick refresher helps — the final stretch assumes you remember where Uryu’s loyalties stood, what happened to the Soul King, and how Yhwach’s Almighty ability works, since none of that gets re-explained. New viewers should not start here; this is the payoff to a story that’s been building since 2004, and jumping in at Part 4 will spoil or flatten nearly every major reveal from the first three parts.

Final Verdict

BLEACH: Thousand-Year Blood War Part 4 — The Calamity is doing something few long-running shonen adaptations attempt: going back to fix an ending everyone agreed was rushed. Ten episodes, a confirmed weekly schedule through Hulu and Disney+, the original cast and crew intact, and manga-exceeding material built specifically to give Ichigo and Uryu’s arcs room to land. For a story that’s been running since 2004, that’s as close to a proper send-off as it gets.
