Rosie/History

Past
Not much is known about Rosie aside from the fact that she is an Overlord and is one of the most powerful demons in Hell. She became friends with the infamous Radio Demon Alastor and realized he is asexual before he did.

However, from what is seen in the pilot it seems that she owns an emporium.

In the opening of the pilot, Rosie is seen crossing out the name "Franklin" from the emporium's sign since Franklin more than likely perished from the extermination and was subsequently eaten by Rosie's minions afterward.
