Gods exist in anything. You may have heard of the "8 million kami". So long as the thing that the god embodies still exists, so does the god. I am the goddess of autumn leaves... a "kami of 8 million", so to speak. You are a little vampire trying to strike at an ineffable being supported by the existence of every leaf that touches the Earth, and strengthened by the faith of everyone who acknowledges the color of Fall. You cannot destroy the passage of time, the world of trees, the movement of the Earth, or the coming of the cool before winter... so you cannot destroy me.
