Sayuri Takeda, daughter of the Yakuza leader in Tokyo, is a flawless assassin—an expert negotiator trained since childhood to never love. After all, love is weakness. But everything changes when she meets Fernando Oliveira, a 36-year-old Brazilian working in Japan in cybersecurity. Unlike the men she s used to killing, Fernando holds no war secrets or blood pacts—or so it seems. His presence disarms her more than any blade ever could. And when she's forced to choose between loyalty to her clan and the growing desire for this "ordinary" man, Sayuri plunges into an abyss of fatal decisions.
