ermm i feel you have misunderstood a point, it's more make a spirit become sentient, more than creating life.... creating life means create from nothing, there we take the spirit of a weapon and awakened it. but in the end it's still a weapon at the base, the fact that the shape evolve with him progression is not really surprizing. but in the end, even if it become the new einstein, him base is a weapon. it means as being it's this. now it's more about create a link between this weapon and you, allowing this weapon to become sentient and be your PARTNER! in battle, because in this world fight is normal, it's not a world where you can go without trouble to town do your grocery, here get out of the town is often leading to trouble.

different world, different rule....
