Speaking of Roman, I think we can safely say now that he's of a noble family, or at least a rich guy's son.

Towards the White Fang, he refers them as animals. Towards the lower tier (Emerald/Mercury), he calls them street rats and punks. During Volume 1 I can't be sure whether it's just racism like Cardin, but his attitude towards Emerald makes it clear that he's used to being at the top.

Why he came to be a professional criminal (and very possibly relinquished whatever status he had before, even though he's still rich), we can guess that something happened during his teenage years that changed his life. He might have always been somewhat a gangster though.
