『Akina Hinatsuru』

Ai's mother and Takashi's wife, and proprietor of a prestigious inn. She attempts to prevent Ai from pursuing a shogi career claiming concern over the stability of such a life. When her daughter failed to satisfy her requirements she attempted to take her back home, but relented and accepted Yaichi's personal request to take her as a disciple under the condition that, should she fail to achieve at least one title before graduating junior high, Yaichi would marry into their family and inherit the inn.
