In a world where nanotechnology governs every aspect of life, Ryu Kazekawa is a man haunted by repeating dreams—visions of a corrupted angel, a collapsing city, and the sisters he couldn’t save.

As Ryu climbs toward a new life with the NTPD’s Nano Division, his past refuses to stay buried. When one of those sisters—Asami—reappears with a mysterious force overtaking her, Ryu is thrust into a war between reality and illusion, tech and myth. Standing in his way is Reeves, a shadowy figure manipulating more than just people—he’s rewriting the rules of the world itself.

Can Ryu break the loop and reclaim what was lost? Or will the entity known only as Seraphim consume everything he holds dear?
