What are the medals in blue dragon for?

It's difficult to tell what "Blue Dragon" refers to without more context. Could you please provide more information? For example:

* What is "Blue Dragon"? Is it a game, a TV show, a book, or something else?

* What is the context of the medals? Are they earned in the game, collected in the show, or something else?

With more information, I can help you figure out what the medals are for!
