| Summary | In the shadowy heart of Tokyo, a clandestine police operation unfolds under the cover of night. Detectives lie in wait along desolate canals, their silence betraying an unspoken dread. When a drunken laborer is violently attacked and left for dead, authorities turn a blind eye—a chilling hint of deeper conspiracies. Enter Homura Sōroku, a sharp-witted detective who infiltrates a covert construction crew under the guise of a plasterer. Dragged blindfolded to a windowless fortress, he uncovers a foreign power’s audacious plot: a hidden artillery cannon, smuggled into Japan under the guise of a goodwill monument, now poised to strike at the nation’s core. As Homura races to unravel the truth, international tensions simmer, and Tokyo’s fate hangs on his ability to outwit enemies lurking in plain sight. Amidst whispers of betrayal and layers of deception, every shadow conceals a threat—and time is running out. |
