Mafia Boss: I Dominate With My Fighting Skills MBF

Due to an extremely unlucky incident, a chance came my way. A chance that could change my life forever.

"No. No. No. I don't need a system. I just want people to care about me. I want them to look up to me and remember me in everything they do. I want to live a fulfilling life. A life that makes me happy."

My words led to a reality that I did not expect.

I woke up in a world where gangs were in control of everything and discovered talents within me that previously lay dormant.

'What? There are no guns?'

Through my fist, the world may sway,
But I may change along the way.

...
PS.

Quite a bit of smut scenes, but they are not the main plot of the story.
