Few offspring from the latest generation of Black's demonstrate the family's core-values the way Yarda does. Although Yarda's versions of them boil down to a simple all out attack, she is one of the rare members that is still accepted as a "true" member. That being said, most also agree that Yarda is basically too agressive to be a good pirate.
Yarda started her 'career' to experiment with the possibilities of space. It wasn't long until this general curiosity changed into an obsession for guns. These days Yarda is mostly found firing at something. This annoying trait has deterred many from flying with her. Only her siblings tend to do it. She herself claims to be a loner and simply to busy to put up with anything except a 'real' pilot.
