It's really happening. BLEACH: Thousand-Year Blood War — The Calamity, the fourth and final part of the Quincy war, premiered on July 25 and is now rolling out weekly. After this, there is no next part: this is the ending Bleach fans have waited two decades to see animated.
What Part 4 covers
The Calamity runs 10 episodes and adapts the manga's final stretch (chapters 664–686) — Ichigo and what's left of the Soul Society making their last stand against Yhwach, the Quincy king who can see (and rewrite) the future. Like the previous parts, the anime is expanding the manga's ending with new content rather than sprinting through it, so even manga readers are getting scenes they've never seen.
The soundtrack situation remains elite: jo0ji handles the opening theme “I-BULL,” with 9Lana on the ending “Rasen.” In the US the series streams on Hulu, with Disney+ carrying it in most other regions.
