Like most RPGs, Yakuza: Like a Dragon features a variety of classes known as Jobs. These Jobs are split between male and female characters, but any character of that gender can have any Job available to their gender. Each character starts with a Job already assigned to them, but you can change their Job and better hone their skills to your liking.
