A diplomat known as the Rasputin of the Ministry of Foreign Affairs, Mamoru Yuki, is arrested by the Tokyo District Public Prosecutors Office Special Investigation Department on charges of breach of trust and obstruction of business by fraudulent means. The charges are fabricated, part of a political purge dressed as a national policy investigation. Yuki, a Russian-speaking intelligence analyst who studied theology in graduate school before joining the foreign service, had spent years working on the Northern Territories dispute and building deep contacts inside the Soviet and later Russian power structure. The story unfolds along two timelines: his past work in Moscow, where he cultivated relationships with high-ranking officials including a hardline second secretary during the 1991 August Coup and later with figures close to Vladimir Putin, and his present ordeal inside the interrogation room. Yuki refuses to confess to crimes he did not commit. The prosecution responds by arresting his associates one by one, including a trading company friend and an influential opposition politician named Toshio Tsuzuki who had worked alongside Yuki on the Northern Territories issue. Each arrest is used as leverage to force a confession. The interrogation scenes juxtapose the brutal psychological pressure of the Japanese criminal justice system, where suspects can be held indefinitely until they admit to the prosecutors constructed narrative, with Yuki's detailed recollections of backroom diplomacy, intelligence work, and the inner workings of both the Japanese Foreign Ministry and the Kremlin. Notable narrative arcs include the 1991 Soviet coup attempt, Yuki's relationship with a mysterious Russian figure known as the Black Colonel, a shadow mission requested by the prime minister to identify the true power behind Putin, and a trip to Israel where Yuki seeks help from Mossad. After months of interrogation, Yuki's mention of the Mossad connection abruptly halts the questioning, as the prosecutors realize the case touches on diplomatic and political taboos. The story moves into the courtroom, where Yuki fights to prove his innocence against a system determined to secure a conviction regardless of the evidence.
