Kain

カイン

Kain, a blue-eyed boy, wanders the countryside and arrives in a town controlled by the "kidoushi"—people from the newborn country of Ren who have a machine implanted in their bodies, granting them power equal to an entire army. The strength of a kidoushi is determined by how much of their body is replaced by the gigai, the machine.

As Kain explores this unfamiliar place, he becomes entangled in the conflicts surrounding the kidoushi and their oppressive rule. With his own mysterious nature and the secrets behind the gigai, he must navigate a world where power and technology clash, facing challenges that will test his resolve.
