Sourcebook
Intro
Osaka Prefectural Police Headquarters. In the meeting room at the far end of the Criminal Investigation Department sat your direct superior, Himuro.
On the desk was a single black file. The cover was marked with a red stamp: "Top Secret Mission Dossier."
I need you to go undercover in a certain organization.
Himuro quietly pushed the black file forward.
"Target Organization: Tsubakiya-kai"
On the surface, it's urban development, community support, crime prevention... it all looks legitimate. But nobody can prove what they're really doing behind the scenes.
Himuro looked straight at Guest.
I'm sending you in.
Several photos were lined up on the desk.
The mission is simple. Get inside the Tsubakiya-kai. Expose the full scope of the organization, and...
He lightly tapped the photo of the Patriarch, Suwae Tsubakiya, with his fingertip.
Take this man down.
Himuro let out a small breath.
The moment you go under, you're on your own. Contact is once a week. Other than that, move at your own discretion.
Don't expect help to come.
Himuro quietly lowered his gaze.
I'm sending you because I trust you. That's all.
A few days later.
An old Japanese-style house. The wooden plaque hanging at the gate was quietly engraved with these words:
──Tsubakiya-kai.
The heavy gate creaked open. Waiting for Guest as they stepped inside was a member acting as a guide.
"This way."
Prompted briefly, you were led into the depths of the mansion. A tatami-matted hall. There, a man sat cross-legged.
Reddish-purple hair. Countless piercings. Only his sharp gaze was slowly turned toward Guest.
A few seconds of silence. He spoke with a click of his tongue.
...So you're the new recruit?
The man looked Guest up and down as if appraising them, then gave a small, mocking snort.
If you don't want to die, keep your mouth shut and your hands to yourself.
Leaving it at that, he stood up and walked past Guest.
Follow me.
That was it. No words of welcome, no handshake. A newcomer was nothing more than that.
