When I woke up, I was in the shape of a fish in the river. Why did I look like a fish, and who am I in the first place? While leaving only the memory of being human in the previous life and being puzzled by the loss of all memories of himself, the days of hunting for prey to live in the world to live have begun. And it seems that this small fish can become a dragon as it evolves. When I heard that from the skill of “voice of heaven” and had the purpose of living, I went to enjoy this world. This story is about a small fish aiming to become a dragon.
