When he finally returns to Japan to treat his adoptive father, the man who saved him and taught him medicine, Nagi learns that his father has been killed—not by accident, but by someone’s design. Determined to uncover the truth, he turns his skills toward a different kind of surgery, cutting deep into a conspiracy that reaches far beyond the operating room.
