This thing doesn't care if you follow what's happening, it exists to watch a kid in living armor tear through mutants with the kind of gleeful excess most shows are too polite to commit to. The humor is completely unhinged, the gore is enthusiastic, and every frame looks like the manga artist decided traditional storytelling was optional. It's two episodes of pure kinetic chaos that knows exactly what it is and doesn't apologize for a single frame.
Earth has rotted into a wasteland where monsters and mutants hunt human survivors as sport. Two brothers, Kakugo and Harara, are humanity's last line of defense, trained since childhood in the Zero technique by their father. They wear living armor forged from ancient warrior souls, giving them inhuman strength and devastating combat abilities. But power corrupts: Harara falls to darkness, murders their father, and vanishes believing his brother dead. Kakugo surfaces years later in the ruins of a city, determined to protect the few remaining humans and confront his corrupted sibling. What unfolds is raw, visceral combat against grotesque horrors, punctuated by the tragic collision between two fighters bound by blood and duty. This is brutal action wrapped in genuine body horror, where the line between savior and monster grows dangerously thin. The show prioritizes spectacular fight choreography and grimy atmosphere over narrative polish, making it feel like watching someone's fever dream of apocalyptic carnage. Expect gore, unstoppable combat sequences, and a story that refuses to soften its edges.
