Chitose Oribe

Chitose is often depicted as an aloof elderly lady who rarely trusts anyone, even to the point that the friendly Shiori Shinomiya sometimes hesitates in meeting her directly. She also tends to treat outsiders rudely, especially if they are associated with Ushimatsu in any way. Somehow, her grudge against Ushimatsu goes to such a point where she would devise ways to humiliate him.
