An assassin who has worked for multiple people, Volke demands gold for whatever job he takes on, regardless of how large or small, though he refuses to tell his reasons for amassing so much gold. Willing to take any job no matter how "dirty" it is, once he takes a mission, he devotes himself to completing it, regardless of how long it would take, though he only takes one job at a time. However, he does seem to hold some morals. A secretive and somewhat amoral character.
