Bleach: Millennium Blood Battle (BLEACH 千年血戦篇 Burīchi: Sennen Kessen-hen?) is an anime series based on Tite Kubo's manga, Bleach, and serves as a continuation of the previous Bleach anime series.

In November 2021, the anime project was revealed to be a television series. The trailer and promotional images for the series were unveiled at Jump Festa '22 on December 18, 2021.

The series will be directed by Taguchi Tomohisa and will air on TV Tokyo starting from October 11, 2022. It will be divided into 4 parts, broadcast intermittently. The first part consists of 13 episodes, concluding on December 27 of the same year. The second part, titled 'The Separation,' will air from July 8, 2023.

Kitani Tatsuya performs the opening theme song, 'Scar' (スカー Sukā?), while SennaRin sings the ending theme, 'Saihate' (最果て?). Kitani also delivers a special ending theme for the first episode titled 'Rapport,' previously used as the theme for the Bleach EX 20th-anniversary exhibition. In the second part known as The Separation cour, the opening theme is 'STARS' by w.o.d., while the ending theme titled 'Endroll' is performed by Yoh Kamiyama.

The acclaimed manga 'Jujutsu Kaisen' (written by Gege Akutami), serialized in 'Weekly Shonen Jump' by Shueisha, has sold over 70 million copies.

The first season of the TV anime aired from October 2020 to March 2021, receiving enthusiastic acclaim not only in Japan but globally, generating massive revenue of 26.5 billion yen. It sparked a significant trend.

The long-awaited second season of the TV anime is set to premiere on 28 MBS/TBS stations nationwide from 23:56 every Thursday starting July 6. In anticipation of the second season, details about the opening and ending songs by Kaidama/Tamaori have been announced.

Aside from his role as a singer-songwriter, the opening theme has become a hot topic by providing songs for various artists such as Ado and Mafumafura. The chosen one is Tatsuya Kitani's “Ao no Sumika”!

Jujutsu Kaisen is considered MAPPA's 'darling' as the anime not only invests in visuals but also meticulously crafts the sound. While not becoming a global phenomenon like Idol, Ao no Sumika by Tatsuya Kitani has received high praise from audiences, leaving an impression even more significant than the opening of the first season.

Heaven Delusion is a Japanese manga series written and illustrated by Masakazu Ishiguro. It has been serialized in Kodansha's seinen manga magazine, Monthly Afternoon, since January 2018. An anime television series adaptation produced by Production I.G aired from April to June 2023.

Heavenly Delusion can be seen as a dark horse anime released in 2023, and the success of the work is partly related to its opening song. With an energetic yet haunting melody, even without watching the show, the audience can anticipate that Heavenly Delusion will be a story with depth and a touch of tragedy (similar to what the opening of Tokyo Ghoul achieved).

The music video, directed by Toshitaka Shinoda (known for Oishi's second single, 'Otomodachi Film,' and YOASOBI's third single, 'Harusion'), features four Oishi-produced versions, all sporting a resemblance to the artist with black-framed glasses, engaging in a whimsical dance performance creating the illusion of five Oishis.

Produced by Liden, the anime adaptation of Subaruichi's fantasy manga, The Legendary Hero Is Dead!, premiered in Japan on April 6, 2023.
