Despite their differing ranks, the three men—Osamu Dazai, the youngest senior officer of the Port Mafia; Sakunosuke Oda, the lowest‑ranked operative; and Ango Sakaguchi, a seasoned intelligence agent—meet each evening at the Lupin Bar to relax and relish the camaraderie that transcends their positions.
One fateful night, Ango vanished without a trace. The only thing that remains of their shared moments is a single photograph captured inside the bar, forever frozen in time.
Years later, Dazai has become a key member of the Armed Detective Agency. The Guild, known for its ruthless corporate tactics, now seeks to seize the Agency"s work permit, believing its investigations threaten their clandestine operations. Dazai, now a seasoned detective, must juggle loyalties between this new adversary and the ever‑hostile Port Mafia.
The tension between the Agency and the Guild escalates as both sides vie for control over the city"s underworld.
