The “Rooster Fighter” anime is confirmed for a Spring 2026 debut, and a new trailer has been revealed. This information was announced at Anime Expo 2025 during VIZ Media’s panel for the series.

The new trailer for the “Rooster Fighter” anime was unveiled alongside a new key visual. The anime is based on Shu Sakuratani’s manga of the same name. VIZ Media is handling worldwide streaming, television broadcast, electronic sell-through (EST), home video, and merchandising outside of Japan, while Hero’s Inc. will manage EST, home video, and merchandising in Japan. Adult Swim is confirmed to air the anime in the U.S., with additional streaming partners to be announced later.

The production staff includes Daisuke Suzuki as director at Studio SANZIGEN, Hiroshi Seko handling series scripts, and Joseph Chou producing. The voice cast features Kenta Miyake as the protagonist Keiji, Mariko Honda as Elizabeth, Shiori Izawa as Piyoko, Tomohiro Ono as Keisuke, and Mitsuaki Kanuka as Morio.

The manga, which debuted on Hero’s Inc.’s Comiplex manga website in December 2020, tells the story of Keiji, a rooster who serves as humanity’s greatest defender against giant opponents, battling them with his “fearsome battle cry—Kokekokko!”. VIZ Media has licensed the manga in English.
