Mafia Boss: I Dominate With My Fighting Skills

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.
