Head Nurse

The hierarchical superior of Mio and all the other nurses. Her slogan is "professionalism, efficiency and rigor" and beware of those who can't keep these goals.

Serious and strict with her younger nurse colleagues who only think about marrying young single doctors, she is more friendly during breaks.

Spoiler

She manages to judge someone right at first sight and she knows that Mio isn't the type of woman to jump on the first single doctor to come. Although she asks her to be more serious at work, she is actually very curious with her doctor colleague about the romance between Takuya and Mio.
