Johnny Garland. Detective, photographer, decent with a knife, has an awesome servant/bodyguard.

Oh, and when he gets pissed, he turns into a fiery angry demonic man ready to unleash havoc on his opponents. Which... pretty much sums him up in a duel: transform and use Ether Purge, watch as the enemy falls over. Granted, with how powerful Ether Purge is, it's not too bad of a strategy to rely on, and its overwhelming power lets him stand amongst some of the best in the DL.
