To me, fanpro 0447 kind of looks like a Knight gone rouge.
He entered knighthood at the request of his parents, but after 5 years of serving the queen he realizes he actually wants to travel the world. He ditches his helmet but is too attached to the remainder of his armor. Unfortunately he had to leave his sword behind.
On his way out he receives the bandana (around his neck) from the queen herself, as a thank you for his service and reminder of his homeland.
He then sets out to see the world. As he travels, 0447 becomes a kind of protector to the people he encounters. He becomes well known with every town he passes through for his brash fighting technique of picking up whatever is nearest to him in order to fight.
A piece of wood, a chair, a bucket, you name it he can fight with it.
But yeah he helps people, and I think that after traveling for a few years he’ll go home to return to knighthood and finally return the bandana.
