Among Kamiura's gang is Kageyama, his most loyal underling. However, the others in the gang view Kageyama with disdain and ridicule him for his inability to get tattooed due to sensitive skin. One day, assassins aware of boss Kamiura's secret arrive from abroad and deliver him an ultimatum: Return to the international syndicate he left years ago, or die.
