“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 kinds 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.

Despite her dark sense of humor, Takemi is nevertheless a very kind and caring person, as one would expect from a doctor; although she gets annoyed at the protagonist for his attempted deception, she decides to make a deal with him afterwards, saying she'll give him medicines to recover his health. After he agrees to become her assistant, she frequently checks on him out of concern for his health.” - Persona 5 Wiki
