Sasaki Satou

Takuya's friend from university and also a friend of Taishi. She comes to do her apprenticeship at the hospital with her friends. She is a very intelligent girl who is straight and strict with herself, finishing her academic duties in advance and being exemplary at work. Since she always finishes her work in advance, she is entitled to longer breaks while the others still have not finished theirs. She loves to charier her friends, Taishi for her academic mediocrity and Takuya thanks to the crisp stories of her childhood told by Mio.
