The beginning

Nastu and Lucy two best friends. But one problem, one of them is a gang leader and a mafia leader! And practically owns the black market. And the best thing. The other is also a gang member! But what happens when Natsu moves? What happens when Igneel makes Natsu take over his job? What will Lucy do?
Crappy description but I am never good at those.
