Recap of Oblivion Battery Season 1
The first season of Oblivion Battery, produced by MAPPA, aired from April to July 2024 and captivated audiences with its unique blend of sports drama and character development. The story, based on Eko Mikawa’s high school baseball manga serialized in Shueisha’s Shonen Jump+ since 2018, follows the “monster battery” duo, pitcher Haruka Kiyomine and catcher Kei Kaname. Their junior high school fame is turned upside down when Kei suffers from amnesia, losing all memory and knowledge of baseball.
The duo unexpectedly reunites at Tokyo Metropolitan Kotesashi High School, an unknown baseball school, alongside other talented players who had previously lost to them and subsequently distanced themselves from the sport. Crunchyroll licensed and streamed the first season, making it accessible to a global audience. The narrative explores their journey to rekindle their passion for baseball and overcome Kei’s memory loss, all while navigating humorous situations and fierce competition. The manga itself has been collected into 22 tankōbon volumes as of October 2025.
What to Expect from the Second Season
While specific plot details for Oblivion Battery Season 2 remain under wraps, the continuation promises to delve deeper into the character arcs and the challenges faced by the Kotesashi High baseball team. With the foundation laid in the first season, fans can anticipate further development of the relationships between the “monster battery” and their teammates, as they strive to achieve their baseball dreams. The returning staff and cast, coupled with MAPPA’s animation prowess, set high expectations for a compelling and visually engaging second season in 2027.
