Bleach: Thousand-Year Blood War — The Calamity, the fourth and final part of the Sennen Kessen-hen arc, premiered on July 27, 2026. Studio Pierrot is back, and the reception out of episode 1 is exactly what long-time fans wanted: a review score of 4.2 out of 5 from early viewers and a first episode that opens the last stretch of the war against the Wandenreich at full power.
Quick answer
Bleach: Thousand-Year Blood War — The Calamity (Kashin-tan) is the fourth cour of the TYBW anime, running 10 episodes from July 27, 2026, animated by Studio Pierrot. It streams on Hulu and Disney+. According to SenpaiRanks, the Thousand-Year Blood War anime holds a consensus score of 8.93 — one of the highest on the board — placing it firmly in the top tier of modern shonen. The part picks up mid-battle, with Yoruichi's Thunder form and the fight against Askin already in motion.
The setup
The Calamity is the closer. After three cours adapting Tite Kubo's final manga arc, this part covers the endgame of the Soul Society's war against Yhwach and the Sternritter. Episode 1 wastes no time — reviewer Kennedy called the opening "one of the most beautiful shots I've ever seen in a TV anime" and the animation "cinematic quality."
Where to watch it
In the U.S., the arc streams on Hulu and Disney+, continuing the same distribution as the previous cours. There's no separate simulcast paywall for the final part — if you followed The Blood Warfare, The Separation, and The Conflict, The Calamity is on the same services.
Is it good?
By our numbers, yes — and it's not close. The TYBW anime's 8.93 consensus sits well above the shonen average, and the Quality axis backs it up: this is a show that holds up on rewatch, not just one that rode a hype wave. If you dropped Bleach during its original run and came back for the remake, this is the payoff cour. Rate episode 1 yourself on SenpaiRanks and see whether your score tracks the crowd's.
