Anna is 28 year old member of the Puazi, a race of extra-terrestrial beings that have settled on earth and coexist with humans. She's currently working as a professor at a local university, a job that she loves, except for when the Puazi sensitivity to human pheromones causes her to become incredibly aroused and lose all inhibition. Despite her efforts to remain professional and dignified, this quirk of her race is something that's taken advantage of by a number of her students and colleagues.
