But as the stakes rise and his path crosses with infamous figures like the Hero Killer and the elusive Eraserhead, Yuji Namura finds himself drawn into a conspiracy far larger than he could have ever imagined. Can he protect his city, keep his secrets safe, and find the truth behind the power that changed his life forever?
