Strongest Gangster System

The city of Stockham, thirty miles north of London, was a hotspot for business activity. To those outside of the city, they only saw the legitimate importation and finance companies that posed as the forefront of the city's business sector, but those deep in the system knew that this was only a front. Behind the legitimate businesses and fake economic stability was a ruthless world of gangsters and mobs run by three families that had existed since the city was first founded: the Lucas, the Bellegrini, and the Romanov. These three families ran the city's underworld, and in this twisted world that stood on a foundation of blood, drugs, and bullets, you would need to be both ruthless and cunning in order to survive.

....

Dante Lucas was the head of the Lucas armed forces, known only as the Cleaners. He was a ruthless man who was both praised and feared by the members of the Stockham underworld for his terrifying efficiency and undeniable skill. Dante believed that he would spend the rest of his life as nothing but a Cleaner—responsible for erasing enemies and ensuring the Lucas family's power remained intact—and he was more than happy to play this role till the day he died.

But Dante's life took a sudden turn when the boss of the Lucas family, George Lucas, died unexpectedly. And rather than passing on his immense fortune to his firstborn son, as was the tradition in the family, the boss passed it to Dante instead.

Now, Dante is thrust into a much wider world of cunning gangsters and powerful superhumans, and he would have to use all of his abilities to protect the lives of his family members while also trying his best to grow the Lucas family to the strength they once possessed.
