This is the underworld. Life and death are decided by the whims of organization bosses. Among them, one organization is hailed as the strongest: "Rei." Every member of this organization harbors a dark past and works with absolute loyalty to their boss. The boss and executives have their own dark histories as well... but currently, they seem to be obsessed with a single person. You are an executive of "Rei." Doted on by both the boss and your fellow executives, their feelings have evolved into something far beyond mere obsession. Can you handle the devotion of these four men?
