Bleach: Thousand-Year Blood War part 4 story: which manga chapters is it adapting?
Bleach: Thousand-Year Blood War part 4 will, of course, wrap up the Thousand-Year Blood War story arc, which has seen Ichigo and Squad Zero do battle with the Quincies and the almighty Emperor Yhwach.
The Calamity adapts manga chapters 664-686, which brings Bleach's mainline story to a close. Given that Thousand-Year Blood War hovers around the 13-episode mark once more, we anticipate creator Tite Kubo will introduce more anime-only scenes and content to pad out and perfect the famously rushed final manga arc.
In terms of plot, we aren't going to go into specifics so as not to spoil what's to come for anime-only viewers. But as the first few episodes have shown, chigo and Yhwach will enter a final battle, with Uryu more than making up for his prior betrayal as he goes toe to toe with Haschwalth.
Bleach: Thousand-Year Blood War part 4 cast
Given the hush-hush nature of anime productions, the Bleach: Thousand-Year Blood War part 4 cast took a while to be fully confirmed. But here they are:
They include Ichigo (Masakazu Morita), Yhwach (Takayugi Sugo), Haschwalth (Yûichirô Umehara), Uryu (Noriaki Sugiyama), Orihime (Yuki Matsuoka), Yasutora (Hiroki Yasumoto), and Yoruichi (Satsuki Yukino), among others.
Is Bleach: Thousand-Year Blood War part 4 the final season?
By all accounts, Bleach: Thousand-Year Blood War part 4 is the final season of the long-running anime.
First debuting in 2004 and running through to 2012, the shonen took a decade-long hiatus before returning with the final Thousand-Year Blood War saga. That was split into four cours (or 'parts') and released across 2022, 2023, 2024, and 2026 respectively.
That's not to say we've heard the last of Bleach. There are light novels aplenty to adapt, plus a No Breaths From Hell one-shot (which takes place after the Thousand-Year Blood War saga as a sequel-of-sorts) to pull from.
Where can I watch Bleach: Thousand-Year Blood War part 4?
Bleach: Thousand-Year Blood War part 4 is streaming on Disney Plus in all territories. Yes, that even includes the US – thanks to a recent shift that will see Hulu fold into Disney's streaming service.
