Double Akutagawa, Double the Fun

I am Akutagawa Ryunosuke. Not long ago, I fought the white Reaper of the Port Mafia. Now I'm preparing to storm the Port Mafia headquarters and rescue my younger sister, Gin. But when my Detective Agency colleagues and I had planned everything and were about to attack, why did the Mafia members in front of me respectfully call me "Lord Akutagawa"? Back at the Detective Agency, I wanted to ask Mr. Ranpo for more details, but then I heard the voices of the man in black who took my sister and the white Reaper?
