Don't Go Gentle into That Good Night

There has never been anything in this world like the human heart. Sometimes we admire it so much, and sometimes we hate it so much. In a world where magic and technology go hand in hand, monsters and humans depend on each other and kill each other. Every species is fighting hysterically for their own purposes. Under the gray and red sky, a young man who doesn't know where he comes from and where he is going is hesitantly dragged forward by this gray world. After facing death again and again, he finally finds himself and the meaning of life.
