Oblivion Battery season 2 has officially been confirmed, with a 2027 premiere window revealed during Jump Festa ’26. It was announced with a dedicated video release that also included a new teaser image, providing the fans with their initial tangible information since the first season of the anime was released in 2024. The confirmation ends months of speculation surrounding the future of the baseball anime adaptation.
As a cue to long-term dedication to the manga by Eko Mikawa, season 2 of Oblivion Battery was announced as part of the anime lineup of the Jump Festa 26. Although the month of the broadcast was not stated, a 2027 release confirmation gives a definite production schedule and proves that the project is not in the initial planning stages anymore.
Oblivion Battery was first aired in April 2024, and it was a one-season show. It has been broadcast internationally by Crunchyroll, which also aired it in Japan, and through this, the series has received a wider audience than the manga readership had. The anime was also unique in that it was a mixture of exaggerated sports drama and the memory-loss comedy, a tone absent in more conservative baseball series.
The first season was produced by MAPPA and had a solid lineup in terms of creativity. The series was directed by Makoto Nakazono, and the series composition and scripts were done by Michiko Yokote. Character designs were by Hitomi Hasegawa, and match production was supervised by Eijuu Takashima to make the baseball sequences feel real in spite of the increased style of the story.
The central appeal of Oblivion Battery season 2 lies in the continuation of Haruka Kiyomine and Kei Kaname’s story. Once feared as an unbeatable “monster battery,” the duo now attends an ordinary public high school after Kei loses his memory. This unusual premise allows the series to explore both elite-level talent and the psychological reset that comes with forgetting one’s own past dominance.

Oblivion Battery season 2 will probably retain the cast. The characters of Haruka Kiyomine (Toshiki Masuda) and Kei Kaname (Mamoru Miyano) revisit their previous parts with much success in the aspects of balancing humour and emotional restraint. Other members of the ensemble include Yohei Azakami (as Aoi Todo), Nobunaga Shimazaki (as Shunpei Chihaya), and Yuki Kaji (as Taro Yamada).
The first season's music has also helped in establishing the identity of the anime. Mrs. Green Apple did the opening theme, Lilac, and Macaroni Enpitsu did the closing theme, Wasurena Uta. Although no music details were announced for Oblivion Battery season 2, the production committee is expected to maintain a similar tonal approach.
Oblivion Battery season 2 and the franchise’s growing reach
Outside the television anime, Oblivion Battery has progressively spread into more formats. The manga was published on Shonen Jump+ in April 2018, and continues to be published concurrently in English by MANGA Plus. The series has been continuing as of September 4, though there was a brief break beginning in June. Volume 23 will be published on January 5.

In October 2020, it was adapted into an event anime by MAPPA, as part of Jump Special Anime Festa 2020. In the same project, Mamoru Miyano starred in the role of Kei Kaname, and he went on to perform the same role throughout the adaptations. More recently, the manga has been adapted into a stage play that opened in Tokyo and Osaka in October, and this again shows how the manga can be adapted to other media.
Although no information on the plot of Oblivion Battery season 2 is revealed, the teaser image indicates a continuation as opposed to a tonal shift. The second season is meant to follow through with the character developments of the first season that were unresolved, such as the fact that Kei is gradually becoming reintroduced into the game of baseball and that Haruka is having trouble adjusting his extraordinary talent to a less competitive environment.
In summary, the second season of Oblivion Battery is planned to be broadcast in 2027, the announcement of which was made at Jump Festa '26. The second season is not a sequel, but a continuation that is planned and executed with the participation of MAPPA, the use of returning cast, as well as manga that still performs well even today. To the series enthusiasts, the news indicates that the monster battery tale is not yet finished.
