Fū's grandmother runs the family café where they live, blending home and business. She excels at confectionery and cooking, actively mentoring others like Norie Okazaki and Komachi Shinoda in baking. Her core philosophy emphasizes that cooking should bring joy to those who eat it, focusing on the emotional connection within food preparation.

Noticeably shorter than others, her stature complements her nurturing yet pragmatic nature. She fosters the café as a welcoming community hub, offering solace and food to family and friends facing emotional hardship, such as comforting Shimako Tobita after romantic rejection.

Memories of her late son, Kazuma Sawatari, are often shared within the family. She keeps his memory alive through stories and photographs, subtly supporting Fū's journey toward accepting his absence. During significant family events, like Fū's father's birthday or graduations, she provides steady emotional support, strengthening bonds during reflective times.

The café extends her role, facilitating social gatherings and community connection. Patrons come not just for refreshments but for companionship, highlighting its importance as an anchor in daily life. Her approach embodies quiet resilience, seamlessly balancing business management with attentive caregiving without overt sentimentality.
