Every story have a messenge and from this messenge the reader learn from it. I been reading Gantz for a while and I still dont understand the theme of the story. But in every Gantz's Volume I see this quote: "Before the World was created, the World already existed. The World was the source of life, and this life brought light to mandkind. The light shines in the darkness, and the darkness has never put it out".
What do you guys think this quote is trying to say??
