The grandmother of Tokine. At the moment she is the most powerful Kekkashi of Karasumori at the moment.
When she was younger Tokiko also protected Karusumori along with her partner Shigemori.In those days she was much more like Tokine and was very calm. At this time they very much respected each other and cared for one another However as they grew older they became to see each other as rivals and hated each other. Long ago it is believed that Shigemori's daughter Sumiko may have contributed to the death of Tokiko's son.
Hakubi has given Tokiko the nickname "Bunny."
According to Shigemori, when Tokiko was younger, if she used too much power, she had a tendency to go on a rampage, losing control and opening up multiple space-time holes before throwing herself into one (Shigemori was the one who usually closed them back up and fixed any resulting chaos). Though she has obviously matured since then, Shigemori still seems to believe it could happen any time Tokiko attempts to go beyond her usual capabilities. Oddly enough, this implies that Tokiko was a great deal like Yoshimori in her youth, and that Shigemori was more like Tokine, at least in that Tokiko had far too much power and Shigemori watched over her in case she went too far.
