Kabaneri of the Iron Fortress

In a world ravaged by the sudden emergence of zombie-like creatures known as Kabane, humanity clings to survival within fortified stations, connected only by armored trains. These steam-powered behemoths, known as Hayajiro, are humanity's last hope against the relentless horde, transporting vital supplies and the last remnants of civilization across a devastated landscape. But when the Kabane breach the defenses of one such station, the fragile peace is shattered, and a new breed of hero must rise. Amidst the chaos, a young inventor named Ikoma, who has been secretly developing a weapon to combat the Kabane, finds himself caught in the brutal struggle. When bitten, he narrowly avoids succumbing to the infection, becoming a Kabaneri—a human-Kabane hybrid with extraordinary strength but a constant battle against his own monstrous urges. Alongside a mysterious and equally powerful Kabaneri girl, Mumei, Ikoma must fight for survival aboard the Iron Fortress, confronting not only the Kabane but also the fear and prejudice of his fellow humans.
