Akane's mother

Akane's mother. She comes to her cafe to take Akane away, but she tastes the coffee Akane made and lets Akane do as she pleases. As she passed away, she said that Hayato was 'his grandson', so it appears that she had a connection with Hayato's grandmother or her grandfather. She later revealed that when she first started, she worked at the embassy as a subordinate of Shigehisa Fuwa 24 years ago, and from that time on, she was a regular at the restaurant operated by Sachiko.
