Bleach: Thousand-Year Blood War – The Calamity is the fourth and final cour of the Thousand-Year Blood War anime, adapting the closing chapters of Tite Kubo’s manga and bringing Ichigo Kurosaki’s story to its conclusion. Produced by Pierrot Films, the season premiered in Japan on TV Tokyo on July 25, 2026, and streams in the United States on Hulu and internationally on Disney+. Returning cast members include Masakazu Morita as Ichigo Kurosaki, Noriaki Sugiyama as Uryu Ishida, Yuki Matsuoka as Orihime Inoue, and Hiroki Yasumoto as Yasutora “Chad” Sado, with Tomohisa Taguchi continuing as chief series director and Hikaru Murata directing the final cour.
From here, this guide focuses entirely on the music: the composer behind the score, the season’s opening and ending theme songs, and exactly what has and hasn’t been officially confirmed about the soundtrack as The Calamity continues its weekly rollout.

Bleach: Thousand-Year Blood War – The Calamity Soundtrack Overview
The music of The Calamity continues the sound composer Shiro Sagisu has built for the Thousand-Year Blood War revival since it began in 2022 — a mix of full orchestra, choir, and heavier rock- and industrial-tinged textures that has carried across the season’s first three cours: The Blood Warfare (2022), The Separation (2023), and The Conflict (2024). Those first three cours were each eventually collected on official soundtrack CDs released by Aniplex: TV Animation BLEACH THE BLOOD WARFARE Original Soundtrack I (released September 27, 2023) and Original Soundtrack II (released December 18, 2024).
As of this writing, Aniplex has not announced a dedicated score album for The Calamity. Given the pattern of the previous volumes, a third soundtrack release covering this cour’s score is plausible once the season concludes, but nothing has been confirmed. What has been officially released and confirmed are the season’s two theme songs: opening theme “I-BULL” by jo0ji, released digitally worldwide on July 24, 2026, and ending theme “Rasen” by 9Lana, released digitally on July 25, 2026 — both distributed internationally through Milan Records.
Who Composed the Bleach: Thousand-Year Blood War – The Calamity Score?
Shiro Sagisu has scored every incarnation of Bleach since the original TV anime began in 2004, making The Calamity the closing chapter of a musical relationship with the franchise that spans more than two decades. Born in Tokyo’s Setagaya ward, Sagisu started his career as a member of the jazz fusion band T-Square before moving into full-time composing and arranging in 1979. He is currently president of P Productions, the anime and tokusatsu production company founded by his father.
Outside Bleach, Sagisu is best known internationally for composing every entry in Hideaki Anno’s Neon Genesis Evangelion franchise, including the Rebuild of Evangelion film series, work that earned him the Tokyo Anime Award for Best Music in 2010 for Evangelion: 2.0 You Can (Not) Advance. His other major anime and tokusatsu credits include Berserk (2016–2017), the live-action Attack on Titan films (2015), Shin Godzilla (2016), Shin Ultraman (2022), and Gridman Universe (2023). Across Thousand-Year Blood War, Sagisu has been credited with returning to a heavier, more orchestral-industrial hybrid sound specifically tailored to the arc’s darker, higher-stakes tone.

Score Highlights
Because no official score tracklist has been released for this cour, individual score cues cannot yet be named or described with confidence. What can be reported with certainty are the season’s two vocal theme songs:
“I-BULL” by jo0ji (opening theme, 4:00) — jo0ji, an artist from Tottori Prefecture who also performed the ending theme for Jujutsu Kaisen: The Culling Game Part 1, wrote and composed the track himself. The artist has described approaching the song with a strong sense of responsibility toward the franchise, aiming to capture what courage means through a more J-rock-leaning sound than his earlier releases.
“Rasen” (Spiral) by 9Lana (ending theme, 3:10) — 9Lana’s ending theme combines band-driven rock energy with orchestral strings. According to promotional materials from Sony Music Japan, the song draws on Ichigo Kurosaki’s arc across the series — themes of loneliness, resolve, despair, and hope — and marks the singer’s first venture into a straightforward rock sound. An acoustic version of “Rasen” followed on August 23, 2026.
Once an official score album is confirmed, this section will be updated to cover specific incidental-music highlights, in line with JSAN Media’s standard for hedging any scene-to-track associations that are analytically inferred rather than officially documented.
Bleach: Thousand-Year Blood War – The Calamity Licensed Songs / Needle Drops
Confirmed absence, not oversight. Thousand-Year Blood War is driven almost entirely by Shiro Sagisu’s original score rather than licensed outside music, and this pattern holds for The Calamity. Checks of SeekerTune, Tunefind, and WhatSong for the season returned no listings of licensed needle drops beyond the confirmed opening and ending theme songs covered above. No additional insert songs have been announced by Aniplex, Viz Media, or TV Tokyo as of this writing.
