This is a Sakamoto Days Fanfic...
--
Sealed in that capsule for six agonizing years, I was finally freed by a mysterious figure whose face I never saw. I don't know who this person is or why they chose to release me, but the only trace they left behind was a heavy coat, draped over my body like a shield against the cold world I was reentering.
Years have passed since I was freed from that hellhole. Now, I live independently, using everything I learned during my captivity. Manipulation, charisma-these are the tools I wield to seize control, and I've mastered them all. I've built a reputation as an agent for hire, running a solo business that's become infamous in the dark alleys of Japan. Despite the illegal nature of my work, I remain untouchable. The authorities can't catch me, nor can they uncover anything about my true identity.
But the longer I live in this shadowy world, the more I feel something inside me fading away. It's a creeping emptiness, a void that grows deeper with every twisted encounter, every deceitful game I play. Yet, instead of despair, I find myself oddly amused, even satisfied, by the darkness I've uncovered. The world is far more twisted than I ever imagined, and the depths of its corruption are endlessly entertaining.
If it weren't for that unknown figure who saved me, I would never have witnessed these events unfold. Whoever they are, they gave me more than just freedom-they gave me a front-row seat to the most twisted show this world has to offer. And for that, I am eternally grateful.

(this may include just a little 18+ and above aka sex. I'll have a warning at the top of the chapter if you wish to skip it, and also this takes place before Mugen Train! Hopefully, this isn't to confusing for you)
