yuzuha is oboro's younger sister and friend to arurū and camyu. she is blind and has been very sick with an unknown illness all her life. although bedridden most of the time, her senses of smell and hearing have been whetted by her lack of sight, enabling her to recognize a person by their scent or even the sound of their footsteps. yuzuha possesses a gentle persona, which she made especially apparent when dealing with her older brother, and in the fact that she refuses to let an animal die in the hope of obtaining a cure for her. sadly, at the end of the last episode (set an unknown time after the events of the main series, but with the characters of similar age and appearance) she is presumed to have died, as oboro is seen visiting her grave and leaving behind the bell that she liked.
