God Beast Master

In a world without fighting spirit and magic, standing at the top of all living beings are various extraordinary creatures called gods. In this world, people are not the absolute protagonists. In other words, every living thing except humans possesses powerful extraordinary power. Mountains, rivers, elements, animals, and even machines and weapons may all become extraordinary creatures. After all, God loves the human species and gives humans the ability to sign contracts with all other creatures. Extraordinary creatures that sign contracts with humans can also grow faster, which allows humans to gain a foothold in this world. But not all creatures are willing to surrender to humans, temples, abyss, endless sea, eternal forest... Their king does not want to share authority with such inferior creatures. The kingdoms of humans and supernatural beings are also at constant war. And in such an era, a special beast master appeared.
