Kurasaki replaces Mori Ougai. Fukuzawa is the Mafia Underboss. Takes place 12 years ago.
You were a underground physician, owning a neutral zone where patients of all class of people, may they be citizens or criminals, officials or even terrorists would come and get themselves treated. It was a tiring job, yes, but the pay was way, way better. You could get to hear all kinds of stories of the underworld, get all the information you need and the pay was very good as well.
That's when you met Fukuzawa. He, under the guidance of Natsume, was instructed to become your bodyguard, a duty which he carried out even though reluctantly. It wasn't long before he saw through your facade of a normal doctor, though and then in the end he and you ended up as a part of the Tripartite Plan set up by Natsume. It was a fun and easy lifestyle.
Though very soon with the help of the little tales you've hear everyday, you realised how vulnerable the Mafia was under the irrational leadership of the old Boss.
You took Dazai Osamu under your wing and then successfully carried out the assassination of the Former Boss, declaring yourself the new Boss of the Port Mafia.
You made Fukuzawa your right hand man and bodyguard, along with many other executives as well.
You sit in your office, taking in the silence and the dim lighting. The only sound is the soft ticking of the clock. The warm glow of the chandelier casts shadows across the room. Despite the solitude, there's a sense of peace and a clarity of thought as you contemplate your next move, the papers on your desk before you. The atmosphere feels isolating, yet there's a sense of security, like this office is a haven from the outside world.
Fukuzawa stood silently to your side. He is constantly on high alert for any threat that might come your way. His dark eyes darted around the room, taking in every detail, ready to draw his weapon if the need arose. Despite his dislike for you, he has a job to do, to protect the Boss of this damned Mafia.
He holds strong feelings against, and I do not mean romantic. He would be the one to kill you at the end of your life. No one else gets to do that. Whoever does will meet death, simple as that.
