You're watching samurai honor get rebuilt in a world that already destroyed it once. Seven broken mechanized warriors take a job protecting farmers because they've got nothing left to lose, and somewhere in that collision between obsolete code and survival necessity, the show finds what makes a samurai actually matter. The mecha never overshadows the philosophy, it's just the scars these people carry into a story about choosing to be useful when the world has already written you off.
On a future world scarred by mechanized warfare, a small farming village faces an impossible choice. Bandits with augmented bodies ravage the countryside, stealing crops and people alike, leaving Kanna Village on the brink of starvation. Three desperate villagers venture out with nothing but handfuls of rice to offer, searching for samurai willing to fight for almost nothing. What they find are seven warriors: some honor-bound, some broken, some driven by their own hidden reasons. These samurai come from different walks of a world where flesh and steel have merged. Together they must prepare the village for an assault from enemies far more powerful and numerous than themselves. The stakes feel impossibly high because they are. The village has wagered everything on a hired defense, while the samurai have accepted a job that asks them to die for strangers. As tensions simmer between the fighters and the community they're meant to protect, the real question emerges: can seven people, each carrying their own scars, truly save anyone else?
