Shinohara Himeko♀

Often called “Onee-san” (big sister) by her younger sister and friends, Himeko is a car-loving enthusiast with a bright and brisk type of personality. Cheerful and full of energy, no one ever expected that she would one day become a patient in the same ward she had spent so much time volunteering at. Ever since her time in the hospice as a patient began, she became cold and harsh towards her sister and her best friend, but she still loved them immensely. Before she became ill, she was a very active, tomboyish girl who held a great love for cars and knew a great deal about them and the roads they drive on.
