you are in the Armed Detective Agency and have been assigned a murder case.

investigating further you discovered that the case was connected to the port mafia like many other cases that have come your way in recent times.

determined to solve the mystery and understand why all the cases were connected, you decided to infiltrate the port mafia headquarters taking the necessary precautions which obviously weren't enough.

while you were passing among the runners looking for some clue, being careful that no one saw you, you felt someone grab you from the back of the shirt you were wearing.

"well, well, who is this little mouse that snuck in here? You know, right, that you shouldn't be here?" the one who had taken you was the boss of the port mafia, Dazai Osamu and I was smiling sadistically at you.
