Yongou x Keibi

S&D Securities’ Fourth Guard is made up of polished, intelligent professionals with exceptional combat training. But when a reckless young man appears, he becomes fixated on intelligence manager Taki Keiichi—and refuses to let go. Because of a past assignment, Taki has drawn the attention of the yakuza, and now this persistent rookie is determined to recruit him. “I’m not leaving until you either come with me or kill me!” Amused by the youth’s earnest ultimatum, Taki allows Yuuki to stay under the pretense of serving as his personal bodyguard. Yet Taki soon finds himself overtaken by a growing desire to dominate the ever-obedient Yuuki. Kogami Shinobu is the undisputed cool beauty of the Intelligence Department within S&D Securities’ Fourth Guard, a unit where suave and brilliant specialists congregate. Nevertheless, he seems indifferent to the pursuit of his easygoing partner, bodyguard Miharu "Shin" Shinnosuke. Why does Kogami so stubbornly refuse to let business and personal feelings mix, as though he fears it? Then, without warning, Shin appears to turn his attention toward a new charge he has been assigned to protect. What will become of their partnership now?
