If you want something more narrative Monsterhearts is exactly this.
Monsterhearts' focus on sexuality might come as a bit of a culture shock, though. I think Urban Shadows might be a better stepping-stone, although it does also have a baked-in focus on politics.
Unless everyone's been lying to me and the next bunch of episodes are The Great Divide II, The Great Divide III, Return to the Great Divide, and Bride of the Great Divide, in which case I hate you all and I'm never touching Avatar again.
