Chitose is Hiroshi's younger sister. She is very courageous and always puts others before herself. Since she is suffering from a serious heart defect, she can't even get out of her bed, but she is truly happy to hear that her brother returned to the village after such a long time. She can't make new friends because of her condition and so that's why she cherishes every moment that she can spend with her dearest brother and sister that are visiting her often. She will take a special liking to Oujo's stuffed cat-like doll, Archimedes.
