He (I'm still thinking of name) is a master builder, miner and inventor, although he was very young he has developed a very intuitive quality to build different things, being very innovative in being able to use non-magical elements to build anything, surpassing even magical weapons, eventually Amatsu-Mikaboshi propose a duel, both will show a weapon capable of killing a God.
Mikaboshi brought a sword that he himself forged in the deepest places of the Japanese hell, a weapon capable of causing the physical body to invert and the divine essence to be destroyed while the Young master brought nothing, there was no ax, not even a bow or sword
Curious, The August Star of Heaven asked him why he brought him nothing, then the master blacksmith told him that the ultimate weapon was simply planning and mind, because it is easier to make a God fight against another God of a different pateon, if you give him the right cheated.
The God who represented the void accepted his response, offered him the power to save any of his creations in nothingness itself
