The native farm is terrorized by robbers. A beast from a different dimension wanders through the forests. Neutrality with the neighboring kingdom hangs in the balance, and powerful sorcerers, instead of solving problems, are increasingly stuck in a meaningless bureaucracy. This is how Kai Nari found his house, returning from the imprisonment of the border world. The bloody rituals of iron-faced sorcerers did not pass without a trace for him. Now he is the bearer of a dangerous creature, whose mind is outside the universe, and whose flesh is steel from dark matter. Creation of the Great Blacksmith. Ancient immortal hunter. Involuntary defender of the world of people from demonic invasion. One body for two? It was not.
