Backstory: Coming from a long line of detectives, Arlen had no interest in the family business and instead wanted to become a famous musician. Things didn't work out so well though, and he found himself performing for cheap, and in less than savory places. After only a few years in Canalave with relatively little success, he was ambushed walking back from a gig in one of it worst areas, and the lute that had been in his family for generations was stolen by a gang. It was his most prized possession, and as a result, he decided to do everything in his power to get it back. This included performing in even less savory places, looking for leads as to the whereabouts of the gang. Eventually, he got it back by buying it from a pawn shop for an exorbitant amount of money, but his grudge against the gang never faded. They had tried to tarnish his work, which in his eyes was unforgivable. The money for the lute came from his father on the condition that he would enter the family business, and knowing what little success he had in music, he reluctantly agreed. He was already familiar with the vast network of criminals through his work in finding the lute, and eventually, he was picked up by an agency because of his connections and his family name.

One of his first jobs was stopping the theft of pokemon eggs and one of them hatched into a Swablu that became his partner in both music and detective work.
