Takemi is a somewhat eccentric young woman. She dresses like a punk and has a morbid sense of humor, reacting with glee when she gets the protagonist to try out a new medicine, watching him squirm. Due to her bad reputation, she can easily tell when one of her patients has an ulterior motive, as those kind of patients are all she gets. Her reputation as "the Plague" has made her highly cynical and insecure, claiming that she's only good for making experimental drugs, even after being praised for curing a young girl.
