"Here I am." Despite how difficult it was to find it, but I never expected it would be here, out of all places, in the most obvious places of all, at the heart of Yokohama. Thankfully, once I arrived at Yokohama, it didn't take me that long to know where their office is.
"There you go." Said the waitress of the cafè that operates on the floor below their office as she handed me my cup of espresso. I wonder why the hell would the Armed Detective Agency have their office on the floor above the cafè. Despite the fact it is dangerous, I didn't see any reason why would they choose this place out of all.

"Riza, after you find out where they operate. Sneak into their office and collect as much information as possible on their personal lives."
"But master, what if they already noticed the fact that I'm a spy? Since they are gifted detectives, I don't doubt that they will have that as a possibility."
"Do I have to remind you of your position?" The blonde-haired old man narrowed his wine-coloured eyes at me, "If that where to happen, then report to me at once," the man turned his back to me, "then kill yourself on the spot." He order before leaving the room.

Despite the fact that master had always been harsh on us, I had no choice but to follow him since he was the one who raised me. But for him to go that far, I guess taking down those bunch of detectives really does mean something important to him. I had always heard him yell and curse their names whenever some of my colleagues got caught by the police. I guess they were the cause...
Now the question is... how do I infiltrate? From what I can see, they are totally unlike Port Mafia who operate under a company building, yet people don't know that what lies inside that building is Port Mafia, but as far as I know, the police might be the one ones who know about this, or so did master tell me.
I took a sip from my Espresso when the light bulb in my mind had brightened up. This cafe really serves amazing coffee. The fact that it both tasted really beautiful and nostalgic aroma really makes me relax. Let's try joining them. I'll be a detective and then I'll be able to enjoy this cup of coffee everyday!
