Ryōko is a Kitsune who lives in an undisclosed Fox Temple somewhere in Tottori Prefecture, in Japan. Nobody knows exactly how old she is; on the outside, she appears to be in her early 30s, but she is actually hundreds of years old. She suffered weak eyesight when she was younger, which only got worse with age (and with injuries she's sustained a long time ago), up to the point where she has become completely blind. As a result of this, however, her other senses became even more powerful.
