“I like shady dealings,” purrs undercover superspy Yabuki en route to infiltrating a sadistic, trigger-happy gang of international jewel thieves. Gone renegade from the shadowy espionage bureau that honed his killer instincts to a razor’s edge, the implacable Yabuki teams up with fellow mercenary crime fighter Yamawaki. Together, they follow a trail of stolen gems leading from the final days of WWII to a contemporary conspiracy that reaches into the highest corridors of corporate power and nefarious international villainy.

A killer driven by revenge tracks down and murders the five women who sexually molested his mentally unstable best friend and drove him to suicide. All the while the police search the underworld for the killer, the press plays up the sensational sex killings, and the killer himself finds his resolve weakened by his budding romantic relationship with a pretty young shopgirl.
