Nozomi Otonomiya (音之宮 のぞみ Otonomiya Nozomi) is the older sister of Saku Otonomiya who was previously being kept in a hospital and now lives with him back home.
Nozomi has long light brown hair that is braided over her right shoulder with bangs swept to the right side and purple eyes.
Nozomi has a very relaxed disposition who is kind to others.
It was Nozomi who first told Saku Otonomiya of the white spirits and how they can heal any injury when they were younger.
Some years later, Nozomi is being kept at the Tensho University Hospital where she is upright and talkative when Saku visits her to deliver some clothes as she has a drip in her arm.
Seeing the doctor arrive Nozomi answers him that she feels much better, her fever is down.
The side effects of receiving further medication is that she is sleeping when Saku visits.
Saku is Nozomi's younger brother who visits her at her hospital bed every day. She finds it very useful and thanks him for coming, telling him to be careful when he heads out for work.
