Genocidal Organ (虐殺器官, Gyakusatsu Kikan) is the debut novel of Japanese science fiction writer Project Itoh.

When Sarajevo was destroyed by a homemade nuclear weapon, the leading democracies of the world transformed into surveillance states, where each individual is constantly monitored, watched, and wired.

Those developing countries went from harmony to complete destruction in about 6–8 months, with all of the events and evidence pointing to one suspect, an American named John Paul.

Clavis Shepherd, a US Special Forces Officer, along with his team of advanced super-soldiers, are tasked with finding and eliminating John Paul.

He leaks the information so that he can be called to a military hearing in Washington DC, watched from afar by the Joint Chiefs of Staff and the general public.
