I Become a Mafia in the Academy Chapter -- Discussion

I like the concept of mafia or something like gangster but mafia/gangster in the academy which is a hero school? They don't do anything mafia worthy to be honest. It's more like a second-generation villain in the hero academy. It will be okay or at least a novel you read just to get by but the line or dialogue is weak, like really really weak.

MC uses his family connection and power but does not just give his full name, which will automatically scare people but you know what, No. He uses almost everything but the name of the group itself. How come almost nobody recognizes the MC who is the heir son of the godfather of the underground world? Even the heir of the direct subordinates. But any of that is just really a minor problem. As I said the top line/dialogue needs to be improved.
