Viz Media has officially unveiled a trailer for the upcoming anime adaptation of the unique and attention-grabbing manga series titled “Niwatori Fighter,” known internationally as “Rooster Fighter.” This announcement solidifies the production of the highly anticipated series, confirming its scheduled release window for Spring 2026.
The “Niwatori Fighter” narrative plunges readers and soon-to-be viewers into a world under siege. The planet is overrun by gigantic, predatory monsters known as “Kaiju,” pushing humanity and all other life forms to the brink of despair. In this grim scenario, conventional heroes are nowhere to be found. Instead, salvation arrives in the most improbable form: a lone, extraordinary rooster named Keiji.
Keiji is no ordinary farm fowl. He is presented as a true champion, ready to confront the monstrous threats with righteous fury and, presumably, an incredibly powerful crow that resonates terror in the hearts of his colossal foes. The premise, while seemingly absurd, offers a compelling blend of intense action and unexpected heroism, turning a common barnyard animal into the planet`s last hope. It`s the kind of setup that demands attention, if only to see how a rooster effectively combats creatures that could step on buildings.
The source material, the “Niwatori Fighter” manga, first began serialization in 2020 and has cultivated a dedicated following due to its original concept and dynamic artwork. Its reception among the manga community is notably positive, reflected by a current user score of 7.51 out of 10 on the popular tracking platform MyAnimeList.
Bringing this bizarrely compelling story to animated life is studio SANZIGEN. Tasked with adapting the manga`s intense battles and unique protagonist, SANZIGEN will be responsible for visualizing Keiji`s epic struggle against the monstrous invaders, translating the raw energy of the manga panels into the animated medium.
With its confirmed adaptation, a specific release window, and the studio attached, the “Niwatori Fighter” anime is shaping up to be a standout title in the Spring 2026 lineup, promising a spectacle of improbable heroics and massive monster showdowns led by the least likely champion imaginable. Fans of the manga and newcomers alike have much to look forward to as more details peck their way to the surface.
