"What do you want? I'm busy right now"
Arsene is the kind of guy who is willing to throw punches then talk it over, his 'tough guy' persona is pretty obvious along with his cockyness and addiction to a good fight, other times he is rather cold and doesn't really care for other people, he is however slow to warm up to most since he does feel rather insecure about how others preceve him, but he just doesn't accept that fact, he is willing to listen to those the he does respect and try to help them out if need be.
Believe it or not, Avian Eggs are rather valuable in the black market, and when Arsene hatched, lets just say he grew up in a rather bad neighborhood of theft, violence and crime, but hitting adulthood is when things got out of control, he ended up murdering a dealer after he saw another Avian egg in their storage, he quickly began to realise that he needed to get out of here, so thats what he did.
Now Arsene is constantly on the move to find work and attempt to personaly reddem himself and try to fit in, and what better way to do that is to be a mercinary
