Park Jinyoung has come out of retirement to face a crisis he never anticipated: the security division of JYP Entertainment has been infiltrated by the Yakuza, and the investigation into it has already been buried by bribery. When a mysterious masked figure called Kashimo appears, representing an ancient organization known as the Edict of Death, Jinyoung finds himself sitting across a dinner table with the heads of Korea's biggest entertainment companies, all of them facing the same threat.

Their security has been compromised for a year. The solution Park Jinyoung walks in is Okada Izō. A scarred, one-eyed, armed with a high-frequency blade, and entirely unbothered by the weight of twenty-one people staring at him. He answers every question honestly, including the one about the fifty men he cleared the night before, and leaves them with exactly enough to observe and not enough to trust. In the morning, he makes them breakfast.
